The Founding of Israel and the 1948 Arab-Israeli War

The establishment of the State of Israel on May 14, 1948, and the war that followed immediately upon that proclamation stand among the most consequential events of the twentieth century. They gave rise to a new nation, shattered an ancient society, and set in motion a conflict whose reverberations have never fully subsided. To understand those events properly requires tracing a long chain of causes that stretches back through the European Jewish experience of the nineteenth century, through the age of competing nationalisms and colonial promises, through the catastrophe of the Holocaust, and ultimately through the blood-soaked months between November 1947 and the summer of 1949. The founding of Israel was simultaneously an act of national liberation and, for the Palestinian Arab population of the country, a catastrophe so complete it has been known ever since by a single Arabic word: Nakba. Holding both truths in mind simultaneously, without diminishing either, is the essential task of any serious account of how Israel came to exist and what the Arab-Israeli War of 1948 actually was.

Zionism's Origins and the European Jewish Question

Modern Zionism emerged from the particular agony of European Jewry in the late nineteenth century. Jews had lived in the Diaspora — scattered across Europe, North Africa, and the Middle East following the Roman destruction of the Second Temple in 70 CE and the subsequent suppressions — for nearly two thousand years. In medieval and early modern Europe, Jews occupied a precarious legal and social position: confined to ghettos, excluded from land ownership and most professions, subjected to periodic violence, and liable at any moment to expulsion. The expulsion from Spain in 1492, perhaps the most dramatic single such event, sent hundreds of thousands into exile across the Mediterranean world.

The Enlightenment and the liberal revolutions of the late eighteenth and early nineteenth centuries briefly seemed to promise emancipation. In France following the Revolution, Jews received full civic equality. Other European states followed, some grudgingly. Jews poured into the universities, the professions, commerce, and the arts with a speed that reflected generations of pent-up intellectual energy. Yet emancipation did not bring the full acceptance its promisers had implied. A new, secular form of anti-Semitism arose to replace the old religious variety, now grounding Jew-hatred not in theology but in pseudo-scientific racism, economic conspiracy theories, and social resentment of the newly visible Jewish professional class.

Nowhere was this contradiction sharper than in the Russian Empire, which contained the world's largest Jewish population, some five million souls confined to the Pale of Settlement in eastern Poland, Lithuania, Belarus, and Ukraine. The assassination of Tsar Alexander II in 1881 unleashed a wave of state-tolerated and state-organized pogroms — violent mob attacks on Jewish communities — that killed thousands, destroyed property, and made plain that Jewish life in Russia rested on a foundation of sand. The word "pogrom," meaning "devastation" in Russian, entered the global lexicon from these events. Similar, if less violent, currents ran through Romania, the Habsburg lands, and Germany.

It was out of this environment of threatened emancipation and resurging persecution that modern Zionism grew. Leon Pinsker, a Russian Jewish physician, published "Auto-Emancipation" in 1882, arguing that anti-Semitism was a pathological but ineradicable feature of non-Jewish societies and that the only cure for Jewish insecurity was Jewish self-reliance in a territory of their own. Other thinkers — Moses Hess in Germany, Eliezer Ben-Yehuda in Paris who would later settle in Palestine and devote his life to reviving Hebrew as a spoken language — reached similar conclusions. But it took one extraordinary individual to transform these scattered intellectual currents into a mass political movement: Theodor Herzl.

Theodor Herzl and the Dreyfus Affair

Theodor Herzl was born in Budapest on May 2, 1860, into a prosperous, largely assimilated, German-speaking Jewish family. He was educated in Vienna and trained as a lawyer, though he found his calling as a writer, playwright, and journalist. For most of his early career Herzl embodied the hope of Jewish emancipation: cultured, cosmopolitan, European to his core, optimistic that talent and education could dissolve the barrier of prejudice. He wrote satirical plays for the Viennese Burgtheater and became the Paris correspondent for the leading Viennese newspaper, the Neue Freie Presse.

Paris in the early 1890s confronted Herzl with a shattering education. The French Republic, birthplace of modern Jewish emancipation, was consumed by a vicious wave of anti-Semitic agitation. The popular press spewed hatred. Jewish officers in the French army faced constant hostility. And then came the Dreyfus Affair.

Alfred Dreyfus was a Jewish captain on the French general staff, a patriotic career officer of Alsatian origin. In October 1894 he was accused of passing military secrets to the German embassy. The evidence against him was fabricated; the real spy was a non-Jewish officer named Ferdinand Walsin Esterhazy. Nonetheless, in a trial conducted with barely concealed anti-Semitic fervor, Dreyfus was convicted of treason in December 1894 and sentenced to life imprisonment on the remote Atlantic penal colony of Devil's Island. His public degradation — in which his epaulettes were torn from his uniform and his sword broken before a crowd screaming "Death to the Jews" — was a spectacle of orchestrated humiliation.

Herzl was present or closely following the coverage of this ceremony. He later wrote that it crystallized everything he had been trying not to see. If France — the France of "Liberté, Egalité, Fraternité," the France that had emancipated the Jews a century before — could still erupt in this way, then emancipation was an illusion. Jewish dignity and security could not be entrusted to the tolerance of majority populations. As he walked the streets of Paris watching crowds howl for the death of a man they knew might be innocent but whose Jewishness made him useful as a scapegoat, Herzl reached the conclusion that would reshape the twentieth century: the Jewish people needed a state of their own.

He began writing furiously. In 1895 he produced a pamphlet, "Der Judenstaat" (The Jewish State), published in February 1896, which laid out with remarkable clarity and practicality the case for a Jewish state. The pamphlet argued that anti-Semitism was not an aberration but a structural feature of Diaspora life; that Jews must therefore seek their own territory; that this territory should be organized as a modern state with proper legal and economic institutions; and that the great powers of Europe could be persuaded to charter such a state as a solution to "the Jewish question" that troubled European politics. Herzl suggested either Argentina or Palestine as possible locations, though his heart inclined toward Palestine, the ancestral homeland that lived so powerfully in Jewish religious memory and cultural identity.

The pamphlet was greeted with derision by many established Jewish leaders — particularly the wealthy, influential Jews of Western Europe who feared that the establishment of a Jewish state would call into question their hard-won status as citizens of their own countries. But it electrified the Jewish masses of Eastern Europe, the very people whom pogroms and poverty had already driven to desperation. For them, Der Judenstaat was not an eccentric utopia but a survival plan.

The First Zionist Congress: Basel, Switzerland, 1897

Herzl moved with astonishing speed and organizational genius to convert his pamphlet into a movement. He reached out to Jewish communities across Europe and the Ottoman Empire, launching a newspaper (Die Welt), cultivating contacts among philanthropists and diplomats, and planning what became the founding congress of political Zionism.

The First Zionist Congress convened in Basel, Switzerland, from August 29 to August 31, 1897. Two hundred and eight delegates from seventeen countries attended, along with twenty-six press correspondents representing newspapers from across Europe and North America. The congress was a remarkable event by any measure: the first deliberative assembly of a people that had lacked political institutions for nearly two millennia. Delegates came in formal dress — Herzl insisted on this, understanding that the congress needed to project an image of seriousness and statesmanship. Rabbis in traditional garb sat alongside secular socialists. Representatives from Vienna and Warsaw, from Odessa and London, from communities across the breadth of the Jewish world, debated in German, the lingua franca of Ashkenazi educated Jews, the destiny of their people.

The congress established the World Zionist Organization (WZO), elected Herzl as its first president, and adopted the Basel Program as its founding document. The program stated in plain language: "Zionism aims to create for the Jewish people a home in Palestine secured by public law." That phrase — "secured by public law" — was Herzl's insertion; he understood that Jewish settlement alone was insufficient. What was needed was international legal recognition, a charter granted by the great powers.

In his diary that evening, Herzl wrote with characteristic grandeur: "Were I to sum up the Basel Congress in a word — which I shall guard against pronouncing publicly — it would be this: At Basel I founded the Jewish State. If I said this out loud today, I would be answered by universal laughter. Perhaps in five years, and certainly in fifty, everyone will perceive it." He was off by exactly one year: the State of Israel was proclaimed fifty years and nine months later, in 1948.

Herzl spent the remaining seven years of his life — he died of heart disease in July 1904, exhausted by relentless travel and diplomacy, at the age of forty-four — pursuing the diplomatic charter with desperate urgency. He met the German Kaiser Wilhelm II, the Ottoman Sultan Abdulhamid II, British Colonial Secretary Joseph Chamberlain, and numerous other statesmen. He was offered Uganda (then British East Africa) as an alternative homeland by the British in 1903, a proposal that split the Zionist movement but was ultimately rejected after Herzl's death. He died without achieving the charter he sought, but the movement he had founded was unstoppable.

The Early Waves of Aliyah: Jewish Immigration to Ottoman Palestine

"Aliyah" — from the Hebrew root meaning "ascent" or "going up" — is the term used for Jewish immigration to the Land of Israel (Eretz Yisrael). The Zionist historiography identifies five major waves of aliyah before Israel's independence, each with its own character and historical context.

The First Aliyah, running roughly from 1882 to 1903, was triggered primarily by the Russian pogroms of 1881 and 1882. Approximately twenty-five thousand to thirty-five thousand Jews settled in Palestine during this period, most coming from the Russian Empire, particularly from Ukraine and Romania. They founded agricultural settlements — moshavot — including Rishon LeZion, Zichron Yaakov, and Petah Tikva, often with financial support from the French Jewish philanthropist Baron Edmond de Rothschild, whose patronage was crucial to early Zionist colonization. The First Aliyah immigrants typically had limited ideological commitment to Zionism per se; many were fleeing immediate persecution rather than acting out a nationalist program.

The Second Aliyah, from roughly 1904 to 1914, was more ideologically charged. Its immigrants came predominantly from Russia, many of them young socialist Zionists who had been radicalized by the failed 1905 Russian Revolution and by renewed pogroms such as the devastating Kishinev pogrom of 1903, in which forty-nine Jews were killed and hundreds wounded in a rampage that shocked the world. The Second Aliyah brought some thirty-five thousand to forty thousand immigrants, including figures who would become the founding generation of the Israeli state: David Ben-Gurion, Yitzhak Ben-Zvi (later Israel's second president), and others. These immigrants founded the kibbutz movement, established the first Hebrew-language urban neighborhoods (Tel Aviv was founded in 1909 as a suburb of Jaffa), created the first Jewish self-defense organizations, and laid the institutional foundations of the future state.

The Third Aliyah, from 1919 to 1923, brought some thirty-five thousand to forty thousand more immigrants, many of them Eastern European survivors of World War I and the Russian Revolution. The Fourth Aliyah, from 1924 to 1929, was larger — approximately eighty-two thousand — and was driven partly by the United States Immigration Act of 1924, which sharply curtailed Jewish immigration to America and redirected emigration flows toward Palestine. The Fifth Aliyah, from 1929 to 1939, was the largest and most fateful of the pre-independence waves: approximately two hundred and fifty thousand Jews arrived, more than a quarter of a million people, primarily from Poland and from Germany after Hitler's rise to power in 1933.

By 1947, the Jewish population of Mandatory Palestine had grown to approximately six hundred and thirty thousand, up from roughly eighty thousand at the turn of the century. The Arab population had also grown substantially, from approximately five hundred thousand in 1900 to roughly one million three hundred thousand by 1947. Palestine was thus a land of two peoples, and the rapidly growing Jewish community had built impressive institutional structures — political parties, a labor federation (the Histadrut), a university (the Hebrew University of Jerusalem, founded 1925), a proto-governmental structure (the Jewish Agency), and a paramilitary defense force (the Haganah) — that made it look increasingly like a state within a state.

The Balfour Declaration of 1917

The most consequential piece of paper in the history of the Israel-Palestine conflict is a letter of 67 words, written on November 2, 1917, by British Foreign Secretary Arthur James Balfour to Walter Rothschild, the second Baron Rothschild, a leader of the British Jewish community. The letter, which became known as the Balfour Declaration, read in its entirety:

"Dear Lord Rothschild, I have much pleasure in conveying to you, on behalf of His Majesty's Government, the following declaration of sympathy with Jewish Zionist aspirations which has been submitted to, and approved by, the Cabinet: His Majesty's Government view with favour the establishment in Palestine of a national home for the Jewish people, and will use their best endeavours to facilitate the achievement of this object, it being clearly understood that nothing shall be done which may prejudice the civil and religious rights of existing non-Jewish communities in Palestine, or the rights and political status enjoyed by Jews in any other country. I should be grateful if you would bring this declaration to the knowledge of the Zionist Federation. Yours sincerely, Arthur James Balfour."

Those sixty-seven words carried enormous weight and equally enormous ambiguity. The phrase "a national home for the Jewish people" was deliberate: it was less than "a state" but more than a "homeland." The qualification that "nothing shall be done which may prejudice the civil and religious rights of existing non-Jewish communities" was the British government's acknowledgment that those communities — the Arab majority of Palestine, approximately ninety percent of the population at the time — had interests that needed protection. Yet the declaration nowhere mentioned the political rights of the Arab population, only their "civil and religious rights" — a significant omission that the Arabs noted immediately.

Why did Britain issue this declaration? The motivations were multiple and not entirely consistent. Britain was fighting a desperate war against Germany and the Ottoman Empire. The Foreign Office believed, exaggerating Jewish influence on international affairs, that a pro-Zionist declaration would help bring the United States more firmly into the war (the US had entered in April 1917 but had not yet committed significant forces) and might sway Jewish opinion in Russia (where the revolution was threatening to pull Russia out of the war). There was also straightforward imperial interest: a Jewish colony in Palestine would be beholden to Britain and help secure British control of the approaches to the Suez Canal in the post-war order. Some British officials, including Balfour himself, were motivated by a genuine, if paternalistic, sympathy for Zionism rooted in their Protestant biblical education and their sense that Jews deserved a homeland.

The Balfour Declaration was not a promise made in a vacuum. The Zionist Organization, led by the brilliant chemist and negotiator Chaim Weizmann, had been lobbying the British government for precisely such a declaration for years. Weizmann, who had contributed significantly to the British war effort through his development of a process for manufacturing acetone (essential for cordite, used in artillery shells), had direct access to the highest levels of the British government. His diplomatic skill in the months leading up to November 1917, navigating opposition within both the British Cabinet and the Jewish community itself, was decisive in securing the declaration.

The declaration was endorsed by the other Allied powers — France, Italy, the United States — and was incorporated into the League of Nations Mandate for Palestine in 1922, giving it the force of international law. For the Zionist movement, the Balfour Declaration was a transformative achievement: for the first time, a great power had recognized the legitimacy of Jewish national aspirations in Palestine. For the Palestinian Arabs, it was a catastrophic betrayal — a decision by a foreign power to reshape their homeland in response to the lobbying of a European movement without asking them.

The Hussein-Mcmahon Correspondence and Conflicting British Promises

The Balfour Declaration was not Britain's only promise regarding the Arab world during World War I, and the contradiction between these promises would haunt the region for the remainder of the century.

In 1915 and 1916, British High Commissioner in Egypt Sir Henry McMahon exchanged a series of letters with Sharif Hussein bin Ali, the hereditary guardian of the holy cities of Mecca and Medina and the ruler of the Hejaz. Hussein was considering launching an Arab revolt against Ottoman rule, which Britain desperately wanted: an Arab uprising in the Ottoman rear would tie down troops, cut communications, and help Britain's campaigns in Mesopotamia and Sinai. In exchange, Britain offered support for Arab independence.

The Hussein-McMahon Correspondence, as this exchange became known, was deliberately vague on the crucial question of boundaries — a vagueness that was almost certainly intentional, enabling Britain to make promises without being bound too tightly by specifics. Hussein understood that he had been promised an Arab kingdom encompassing most of the Arab-speaking lands of the Middle East, including greater Syria (which included what would become Palestine, Transjordan, Lebanon, and Syria). Britain's later position was that Palestine had been excluded from these promises by virtue of a phrase in McMahon's letter of October 24, 1915, referring to "portions of Syria lying to the west of the districts of Damascus, Homs, Hama and Aleppo" — a phrase whose geographic meaning was disputed immediately and has been disputed ever since.

The British also made a third set of promises regarding the Middle East through the secret Sykes-Picot Agreement of 1916, negotiated between British diplomat Mark Sykes and French diplomat François Georges-Picot, which carved the Arab Middle East into British and French spheres of influence. Under Sykes-Picot, Palestine was to be under international administration — a proposal satisfying neither Arab nor Zionist aspirations but reflecting British and French desire to share influence over strategically vital territory.

The combination of the Hussein-McMahon Correspondence, the Balfour Declaration, and the Sykes-Picot Agreement represented a tangle of incompatible obligations that Britain could never fully satisfy. When the promises were eventually read together in the harsh light of post-war reality, Arab leaders felt that they had been deceived. Hussein's son Faisal, who briefly ruled Syria before being expelled by the French in 1920, had briefly reached a tentative understanding with Chaim Weizmann (the Faisal-Weizmann Agreement of 1919) suggesting a possible Jewish-Arab accommodation — but that agreement was conditioned on Arab independence being granted, which it was not. The foundations of lasting conflict had been laid not only by the competing nationalisms of Jews and Arabs but by the duplicitous diplomacy of the British Empire.

The British Mandate for Palestine, 1920 to 1948

Following Britain's conquest of Palestine from the Ottomans in 1917 and 1918 — marked most famously by General Edmund Allenby's entry into Jerusalem on foot on December 11, 1917 — Britain administered the territory provisionally until the League of Nations formally granted it the Mandate for Palestine in 1922. The mandate came into effect in September 1923.

The Mandate was unique among the League's mandates in explicitly incorporating the Balfour Declaration into its text. Britain was instructed to facilitate Jewish immigration and the establishment of a Jewish national home, while safeguarding the rights of the existing population. These two obligations were fundamentally in tension, and the tension only increased as Jewish immigration accelerated and Arab resistance mounted.

The 1920s saw periodic violence between the communities. Arab riots in Jerusalem in 1920 killed a number of Jews; the 1921 Jaffa riots left dozens dead on both sides. The Haganah — meaning "defense" in Hebrew — was established in 1920 as a clandestine Jewish self-defense organization in response to these attacks. It would grow steadily over the following decades into a formidable military force.

The fundamental political conflict was over the future of the country. The Arab leadership, organized primarily through the Supreme Muslim Council under the Grand Mufti of Jerusalem Hajj Amin al-Husseini, demanded representative government based on the existing demographic majority — which was Arab. Such a government would have been able to restrict Jewish immigration and foreclose the Jewish national home. The Zionist leadership rejected any arrangement that put Jewish immigration subject to Arab veto. Britain, trapped between these irreconcilable positions and responsible for both, satisfied neither.

In 1929 a dispute over access to the Western Wall in Jerusalem — the most sacred prayer site accessible to Jews, abutting the compound housing the Al-Aqsa Mosque and the Dome of the Rock, Islam's third holiest site — escalated into widespread violence across Palestine. The 1929 massacres killed 133 Jews (most notoriously the Jewish community of Hebron, where 67 Jews were killed by Arab mobs in what became known as the Hebron massacre) and 116 Arabs (mostly killed by British forces attempting to restore order). The violence demonstrated how explosive the political situation had become and how thoroughly the Mandate administration had failed to construct any sustainable political framework.

The Holocaust and Its Catalyzing Impact on Jewish Statehood

No event was more decisive in shaping the trajectory of the Zionist project and the eventual establishment of Israel than the Holocaust — the systematic, state-organized genocide of approximately six million Jewish men, women, and children by Nazi Germany and its collaborators between 1941 and 1945.

Adolf Hitler came to power in Germany in January 1933. The Nazi regime immediately began a systematic program of persecution against Germany's five hundred thousand Jews: stripping them of citizenship (the Nuremberg Laws of 1935), driving them from the professions, confiscating their property, and subjecting them to escalating violence (the Kristallnacht pogrom of November 9 to 10, 1938, in which nearly a hundred Jews were killed, thousands more beaten, and some seven thousand Jewish businesses destroyed). German Jews emigrated in large numbers — a quarter of a million left before the war — but the doors of most countries, including the United States and Britain, were largely closed against Jewish refugees.

For Palestine, Hitler's rise to power triggered the Fifth Aliyah, the wave that transformed the Jewish community's size, sophistication, and economic dynamism. German Jewish immigrants — many of them middle-class professionals, academics, doctors, and engineers — brought European technical knowledge, capital, and culture. Tel Aviv grew rapidly into a modern Mediterranean city.

With the outbreak of World War II in September 1939 and particularly after Germany's invasion of the Soviet Union in June 1941, Nazi policy shifted from forced emigration to systematic annihilation. The mobile killing units (Einsatzgruppen) shot roughly one million Jews in mass shootings in occupied Soviet territory in 1941 and 1942. The Wannsee Conference of January 1942 coordinated the "Final Solution to the Jewish Question" — the industrialized murder of all Jews under German control. Six death camps — Auschwitz-Birkenau, Treblinka, Sobibor, Belzec, Chelmno, and Majdanek — operated primarily on Polish soil. By the war's end, two-thirds of European Jewry, and roughly one-third of the world's Jewish population, had been murdered.

The Holocaust transformed the politics of Jewish statehood in several ways. It destroyed precisely the communities that had been the heartland of the Zionist movement — the Jews of Poland, Ukraine, and the Baltic states. It created approximately two hundred and fifty thousand Jewish Displaced Persons (DPs) in Europe who, having survived the camps, could not or would not return to their former homes and desperately needed somewhere to go. It shifted international opinion: the evidence of the death camps, which emerged fully only as Allied armies liberated them in 1945, created enormous sympathy for Jewish suffering and made it morally very difficult to oppose Jewish national aspirations. And it gave the Zionist argument about the impossibility of Jewish security in the Diaspora a terrible, irrefutable vindication.

President Franklin D. Roosevelt had been evasive on the question of a Jewish state, trying to balance Zionist pressures with his concern for Arab oil supplies and British imperial preferences. His successor Harry S. Truman, a man of genuine moral convictions and significant political debt to the American Jewish community, was more forthcoming. Truman was particularly moved by the plight of the Jewish DPs in Europe — reports by his emissary Earl Harrison describing their horrific conditions in DP camps (some actually located in former concentration camps) provoked Truman to pressure Britain to allow one hundred thousand Jewish DPs into Palestine immediately, a request Britain refused.

The Arab Revolt of 1936 to 1939

Well before the Holocaust's full impact was felt, the consequences of unchecked Jewish immigration had already produced a full-scale Palestinian Arab uprising. The Arab Revolt of 1936 to 1939 was the most sustained and serious challenge to British rule in Mandatory Palestine until independence.

The revolt began with a general strike in April 1936, called by the Arab Higher Committee under Hajj Amin al-Husseini, demanding a halt to Jewish immigration, a ban on land sales to Jews, and the establishment of representative government. The strike lasted six months and paralyzed the Palestinian Arab economy. When the strike ended without achieving its demands, the revolt entered a second, more violent phase beginning in 1937: guerrilla warfare against both British forces and Jewish settlements. Palestinian Arab fighters, often operating from rural bases in the hills of Galilee and Samaria, attacked British military convoys and installations, blew up oil pipelines, and targeted Jewish civilians. British reprisals were severe: collective punishments, house demolitions, mass detentions, and the large-scale use of Arab informers and collaborators. The British also armed and incorporated Jewish forces — including the Haganah — into the counter-insurgency effort, a decision that greatly accelerated Jewish military capability and experience.

The Arab Revolt was ultimately crushed by 1939 at great cost to the Palestinian Arab community. Thousands of Palestinians were killed (estimates range from three thousand to six thousand), hundreds executed, and approximately ten percent of the adult male population was imprisoned, killed, or exiled at some point during the revolt. The Palestinian Arab leadership was decimated: Hajj Amin fled to Iraq and ultimately to Nazi Germany, where he spent the war years in an infamous collaboration with Hitler that would permanently damage his standing in post-war politics. The Palestinian Arab community entered the critical years of 1947 to 1948 without an effective military organization, without competent leadership, and with a population exhausted by years of revolt.

For the Zionist movement, by contrast, the years of the Arab Revolt were years of capacity-building. The Haganah grew substantially in size and sophistication. The British-authorized Special Night Squads, commanded by the eccentric and brilliant British officer Orde Wingate, trained Jewish fighters in aggressive nighttime raiding tactics that would later be central to Haganah doctrine. Jewish institutions in Palestine — the Jewish Agency, the Histadrut labor federation, the kibbutzim — gained experience in coordinating under pressure and in filling the gaps left by a British administration stretched thin by the revolt.

The 1939 White Paper and the Betrayal of Jewish Immigration

In May 1939, with war in Europe clearly imminent and desperate to keep the Arab world from aligning with Germany, the British government issued a White Paper on Palestine that represented a dramatic reversal of its previous policy. Written by Colonial Secretary Malcolm MacDonald, the 1939 White Paper announced that Britain would permit only seventy-five thousand additional Jewish immigrants over the next five years (meaning that Jewish immigration would effectively end in 1944), after which any further Jewish immigration would require Arab consent. It further limited Jewish land purchases in most of Palestine and declared that it was British policy that an independent Palestinian state — with an Arab majority and an Arab-controlled government — would be established within ten years.

The timing was catastrophic. In 1939, with Hitler's Europe closing in on Jewish communities from the Atlantic to the Russian border, with the Final Solution not yet announced but already implicit in Nazi ideology and actions, Britain chose precisely that moment to shut the gates of the one territory in the world that Jews had a recognized right to enter. Jews could not enter the United States, which retained its racially restrictive immigration quotas. They could not easily enter Latin American countries, which were under pressure from their own nativist movements. And now they could not enter Palestine.

The White Paper was condemned by the Permanent Mandates Commission of the League of Nations as inconsistent with Britain's mandate obligations. It was condemned by Winston Churchill, then still a backbencher, as "a base betrayal." It was condemned with volcanic fury by the entire Zionist movement, which now understood that British and Zionist interests had decisively parted ways.

The immediate practical effect was that desperate Jewish refugees from Hitler's Europe, trying to reach Palestine illegally by sea aboard barely seaworthy vessels — a practice known as Aliyah Bet, or "illegal immigration" — were intercepted by the Royal Navy and interned in detention camps in Mauritius or turned back altogether. The most notorious such incident was that of the SS Struma in February 1942: a Romanian vessel carrying 769 Jewish refugees from Romania, the ship was refused permission to dock in Haifa, held in Istanbul harbor for weeks while its refugees pleaded for entry permits, and then towed into the Black Sea, where it sank (possibly struck by a Soviet torpedo that was either a mistake or targeted at what its crew assumed was a German vessel). Seven hundred and sixty-eight people drowned. Similar tragedies involving the Patria (in which two hundred and fifty-two lives were lost when the Haganah attempted to sabotage the ship to prevent its deportation and misjudged the charge) and other vessels added to a toll of preventable deaths that the Zionist movement's propaganda machinery used to devastating effect.

The White Paper also had a decisive effect on the political alignment of the major Jewish underground organizations. The mainstream Haganah, under the authority of the Jewish Agency and David Ben-Gurion, adopted a policy of restrained resistance to the White Paper while cooperating with Britain against Nazi Germany during the war. Ben-Gurion memorably summarized this policy in 1939: "We shall fight the White Paper as if there were no war, and fight the war as if there were no White Paper." Two smaller, more radical organizations — the Irgun Zvai Leumi (National Military Organization, known as the Irgun) and the even more extreme Lehi (an acronym for "Fighters for the Freedom of Israel," also known as the Stern Gang after its founder Avraham Stern) — rejected this accommodation entirely and conducted an armed campaign against British rule during the war years themselves.

The Jewish Underground Organizations: Haganah, Irgun, and Lehi

The three main Jewish paramilitary organizations that operated in Mandatory Palestine in the years leading up to 1948 differed substantially in size, ideology, tactics, and political alignment, but together they constituted the military infrastructure out of which the Israel Defense Forces would eventually be formed.

The Haganah — "defense" in Hebrew — was the largest and most important of the three. Founded in 1920 under the authority of the Histadrut labor federation and later the Jewish Agency, it had by 1947 a membership of some fifty thousand, with a mobilizable reserve of perhaps twenty-five thousand and a trained full-time strike force called the Palmach of some three thousand elite fighters. The Haganah was the military arm of the mainstream Zionist labor movement, and its political orientation was broadly social-democratic. Its command structure was professional, disciplined, and increasingly sophisticated. During World War II, approximately thirty thousand Palestinian Jews served in the British Army, many in specifically Jewish units such as the Jewish Brigade, and returned with valuable military experience.

The Irgun — full name Irgun Zvai Leumi — was founded in 1931 by dissident Haganah members with a more aggressive nationalist ideology aligned with Revisionist Zionism, the movement founded by Ze'ev Jabotinsky that rejected the gradualist, accommodationist approach of the mainstream Zionist leadership and insisted on Jewish sovereignty over all of historic Palestine (including Transjordan). By the mid-1940s the Irgun had several thousand members and was commanded by Menachem Begin, a Polish-born Zionist whose entire family had been killed in the Holocaust. Begin broke with the British in early 1944, issuing a declaration of revolt and initiating a sustained campaign of bombings, assassinations, and raids against British military and administrative targets.

The Irgun's most spectacular and controversial action was the bombing of the King David Hotel in Jerusalem on July 22, 1946. The south wing of the hotel housed the British military headquarters and administrative offices for Mandatory Palestine. The Irgun planted a bomb in the hotel's basement kitchen; despite warnings, British officials did not evacuate in time (whether they took the warnings seriously is disputed). The explosion killed 91 people — 41 Arabs, 28 British, 17 Jews, and 5 others. The bombing horrified much of the Jewish community in Palestine and abroad, was condemned by Weizmann and Ben-Gurion, but also demonstrated the Irgun's ability to strike at the heart of British administration.

Lehi, the smallest and most radical of the three organizations, never had more than a few hundred active members but punched far above its weight in terms of political impact. Founded by Avraham Stern in 1940 after he broke from the Irgun, Lehi believed in uncompromising violent resistance to British rule even during the war against Hitler — a position that led Stern to approach the Germans and the Italians about cooperation (overtures that were rejected). Stern was killed by British police in February 1942 in circumstances that amounted to a summary execution. Lehi continued under a collective leadership that included Yitzhak Shamir, later Israel's prime minister. Lehi specialized in assassinations: it killed British officials, Arab leaders, and ultimately one of the most important international figures to visit the region, Count Folke Bernadotte.

In the summer of 1945, the three organizations formed a short-lived alliance — the Jewish Resistance Movement — for coordinated actions against British rule. This alliance broke down following the King David Hotel bombing. But in the crucial period of 1947 to 1948, as the British prepared to leave and the war between the Jewish and Arab communities began, the three organizations cooperated while maintaining separate command structures, a situation that caused serious tensions.

The United Nations Partition Plan for Palestine, 1947

By 1946 and 1947 Britain was exhausted by the war, financially ruined, facing nationalist uprisings in India, Malaya, and Egypt, and deeply frustrated by its impossible position in Palestine — simultaneously fighting the Jewish underground, facing international condemnation for blocking Jewish DPs from entering Palestine, and unable to produce any political solution acceptable to both Arabs and Jews. In February 1947 the British government announced that it was referring the Palestine problem to the newly formed United Nations and withdrawing British forces by May 14, 1948.

The UN established a Special Committee on Palestine (UNSCOP), composed of representatives from eleven neutral nations, to investigate and recommend a solution. UNSCOP members witnessed at first hand the desperate situation of Jewish DPs in Europe — including the particularly dramatic case of the ship Exodus 1947, which attempted to bring forty-five hundred Jewish DPs from France to Palestine, was intercepted by the Royal Navy, and whose passengers were forcibly transferred back to Germany in scenes broadcast worldwide, generating enormous sympathy for the Zionist cause. UNSCOP produced a majority report recommending partition of Palestine into a Jewish state and an Arab state, with Jerusalem under international trusteeship.

The UN General Assembly voted on November 29, 1947. Resolution 181, the Partition Plan, passed by 33 votes to 13, with 10 abstentions. Under the plan, the Jewish state would receive approximately 56 percent of Mandatory Palestine — including the coastal plain from Tel Aviv to Haifa, the Jezreel Valley, the eastern Galilee, and the Negev desert — though this territory included many Arab inhabitants. The Arab state would receive approximately 43 percent — western Galilee, the central highlands (the West Bank), and the southern coast (the Gaza region). Jerusalem and Bethlehem would be placed under UN trusteeship.

The Jewish Agency accepted the partition plan with mixed feelings — it gave them less than the whole of historic Palestine, including the biblical heartland of Judea and Samaria, and required accepting the partition of their claimed homeland — but accepted it as the foundation for statehood. The Arab states and the Palestinian Arab leadership rejected it outright. Arab League Secretary-General Azzam Pasha reportedly described the Arab response in stark terms: "This will be a war of extermination and momentous massacres, spoken of like the Mongolian massacres and the Crusades." The Arab Higher Committee announced the Arab states would prevent partition by force.

The vote set in motion the cascade of events leading to Israel's declaration and the 1948 war. But the war effectively began the morning after the UN vote.

The Civil War Phase: November 1947 to May 1948

The period between the UN vote on November 29, 1947, and Israel's declaration of independence on May 14, 1948, is often described as the civil war phase of the 1948 conflict — a period in which the Jewish community of Palestine fought the Palestinian Arab community (and irregular Arab volunteers from surrounding countries) before the regular armies of the Arab states entered the war. It was during this phase that the Palestinian Nakba began: roughly three hundred thousand Palestinians were displaced or fled before Israel even declared independence.

The violence began almost immediately after the UN vote. On November 30, 1947, Arab gunmen attacked a Jewish bus near Lydda, killing five. Over the following weeks and months, Jewish and Arab forces attacked each other's communities, towns, and transport routes across the country. Jerusalem, divided between a Jewish population in the western neighborhoods and an Arab population in the east and Old City, was the scene of particularly intense fighting. Arab forces blockaded the Jewish supply road from Tel Aviv to Jerusalem, threatening to strangle the city's Jewish population of one hundred thousand.

The Palestinian Arab community entered this phase at a significant disadvantage. Its leadership had been decimated by the Arab Revolt of 1936 to 1939: key figures were in exile, dead, or imprisoned. Its military forces — the Arab Liberation Army under Fawzi al-Qawuqji, an Iraqi-born guerrilla commander, and local Palestinian irregular units — were poorly organized, outgunned, and lacking the institutional backing that the Haganah enjoyed. The Haganah, by contrast, had the Jewish Agency as its political backbone, the resources of Jewish communities worldwide, and the military experience of tens of thousands of veterans of the British Army.

At the start of the civil war phase, the Haganah was essentially on the defensive, afraid to antagonize the British who still controlled the country, conserving resources, and trying to hold Jewish areas intact while the Arab forces probed for weaknesses. But in April 1948, as British withdrawal accelerated and the military balance became clearer, the Haganah went decisively on the offensive with Plan Dalet.

Operation Nachshon and the Battle for the Jerusalem Road

The Haganah's first major offensive operation of the 1948 war was Operation Nachshon, launched in early April 1948. Its objective was to break the Arab blockade of the Jerusalem road and relieve the besieged Jewish population of the city by capturing the Arab villages that commanded the road. The operation was named for the biblical figure Nachshon ben Aminadav, who according to tradition was the first Israelite to enter the Red Sea when Moses parted it.

Operation Nachshon was the largest Haganah operation to date, involving approximately fifteen hundred fighters — the full strength of the Palmach elite force and additional Haganah units. It succeeded in temporarily opening the Jerusalem road, enabling a convoy of supplies to reach Jerusalem. But it came at a heavy cost and was accompanied by the episode that would become the most controversial single event of the 1948 war: the attack on Deir Yassin.

The Deir Yassin Massacre of April 9, 1948

Deir Yassin was a village of approximately six hundred inhabitants on the western outskirts of Jerusalem, overlooking the main road from Tel Aviv. The village had a reputation as peaceable and had reportedly reached a non-aggression agreement with the Haganah in the Givat Shaul neighborhood nearby. On April 9, 1948, forces of the Irgun and Lehi — operating in coordination with (though apparently without full Haganah approval of their methods) Operation Nachshon — attacked the village.

What happened in Deir Yassin on April 9 remains the subject of historical dispute in its details, but the broad outlines are established beyond reasonable doubt. Irgun and Lehi fighters, perhaps 120 to 130 in number, entered the village in the early morning hours. Fighting was more intense than anticipated — the village had armed defenders — and the attackers suffered casualties. By the end of the day, somewhere between 107 and 120 Palestinian Arab villagers were killed, including an uncertain number of women and children. Some were killed in combat; others were killed in circumstances that witnesses described as executions, including a number killed after they had been taken prisoner. Bodies were thrown down a well. Some survivors were paraded through the streets of Jewish Jerusalem in a display that was intended as a demonstration of military prowess but was widely perceived as a victory march.

The precise death toll — estimates range from 107 to 254 depending on the source — and the precise circumstances of the killings have been contested by historians ever since. But the political and psychological impact of Deir Yassin was not primarily a function of the exact number killed. It was a function of how the news spread.

The massacre was publicized by multiple parties for different reasons. The Irgun and Lehi publicized it as a military achievement. Arab leaders publicized it — and in some cases embellished accounts of atrocities — in an effort to mobilize Arab public opinion and secure intervention by the Arab states. The Haganah and the Jewish Agency publicly condemned the attack while privately recognizing its military benefits. The combined effect was to create a wave of terror throughout the Palestinian Arab population. The story of Deir Yassin spread across Palestine within days, carried by refugees from the village and amplified by radio broadcasts from Arab stations. Palestinian Arabs who had been hesitating about whether to flee began to leave. Towns and villages that received large numbers of refugees spreading stories of massacre accelerated the departure of their own populations.

The historian Benny Morris, in his study of the Palestinian refugee problem, concluded that Deir Yassin was "the most significant" single event in the creation of the Palestinian refugee flood. It was not the only atrocity committed by Jewish forces during the war — Morris and others documented dozens of villages where Palestinian civilians were killed, expelled, or both — but it was the most consequential in its psychological impact.

It should be noted that Arab forces also committed atrocities during this period, including the ambush and killing of 78 Jewish doctors, nurses, and Hebrew University employees in a convoy to Hadassah Hospital on Mount Scopus in Jerusalem on April 13, 1948, four days after Deir Yassin.

Plan Dalet and the Question of Expulsion

The strategic context of the Deir Yassin attack was Plan Dalet (Plan D), the Haganah's operational master plan for the 1948 war, finalized on March 10, 1948. Plan Dalet was the first comprehensive military plan in the history of the conflict that went beyond defense to address the question of territory: specifically, how to establish control over the territory allocated to the Jewish state under the UN Partition Plan, and how to secure lines of communication between Jewish population centers.

The plan instructed Haganah commanders to take control of specific areas and to "cleanse" (in the original Hebrew, lehitkayem) villages that could serve as enemy bases, either by taking them into custody or, if they resisted, by destroying them and expelling their inhabitants. The key operational instruction stated: "Destruction of villages (setting fire to, blowing up, and planting mines in the debris), especially those population centers which are difficult to control continuously... Mounting search and control operations according to the following guidelines: encirclement of the village and conducting a search inside it. In the event of resistance, the armed force must be wiped out and the population must be expelled outside the borders of the state."

The question of whether Plan Dalet constituted a blueprint for ethnic cleansing, or merely a military security plan whose civilian displacement was an unintended side effect, became one of the central controversies in the historiography of 1948. The Israeli "New Historians" who examined the declassified archives beginning in the mid-1980s reached different conclusions on this point. Benny Morris argued that while Plan Dalet did lead to the expulsion of Arab civilians, this was largely a byproduct of military necessity in wartime rather than a deliberate policy of ethnic cleansing formulated in advance. Ilan Pappé, by contrast, argued that Plan Dalet was precisely what it appeared to be: a plan for the ethnic cleansing of Palestine that had been developed by the Haganah leadership, including Ben-Gurion, well in advance of the Arab states' invasion.

What is beyond dispute is the operational result. Between April and the end of the war in 1949, approximately seven hundred thousand to seven hundred and fifty thousand Palestinian Arabs fled or were expelled from their homes, roughly half of the entire Palestinian Arab population of Mandatory Palestine.

The Fall of Haifa and Jaffa

April 1948 saw the fall of the two largest Arab-majority urban centers in the territory of the proposed Jewish state: Haifa and Jaffa.

Haifa, the major port city of northern Palestine, had a mixed Jewish and Arab population of roughly one hundred and seventy thousand. The Arab community was clustered primarily in the lower town near the port; the Jewish community occupied the slopes of Mount Carmel above. On April 21 and 22, 1948, with British forces withdrawn to a small perimeter around the port, the Haganah launched Operation Bi'ur Hametz (literally, "The Elimination of Leaven," referring to the Jewish Passover custom of clearing all leavened bread from the house — an ominous metaphor). Haganah forces descended from the Carmel heights and swept through the Arab lower town with overwhelming force, using artillery and mortars against densely populated urban streets.

The Arab community of Haifa disintegrated with remarkable speed. Arab Higher Committee representatives from outside the city arrived and, over the strong opposition of some local Arab leaders who wished to stay and reach an accommodation with the Jews, ordered the Arab population to evacuate. The reasons for this decision are still disputed: Zionist accounts emphasized the Arab leadership's directive to leave; Arab and Palestinian accounts emphasized the terror created by Jewish military force and the attacks on civilian areas. In practice, both factors operated simultaneously. Within days, roughly seventy-five thousand of Haifa's eighty-five thousand Arab residents had left by sea for Acre and Lebanon, in a chaotic, terrifying exodus that eyewitnesses described as people abandoning everything — property, possessions, livelihoods, lives built over generations — in the desperate rush to escape.

Jaffa, the ancient Arab port city adjacent to the Jewish city of Tel Aviv (they are now a single municipality), fell slightly later, at the end of April and early May. Jaffa was outside the territory allocated to the Jewish state under the UN Partition Plan — it had been assigned to the Arab state as an enclave — but the Irgun began attacking it from early April with mortar fire that caused civilian casualties and panic in the crowded Arab neighborhoods. After a brief British counteraction, the Irgun attacks resumed; the Haganah then joined the assault. By early May, Jaffa's Arab population of seventy-five thousand had dwindled to a few thousand as the rest fled north, south, and east.

David Ben-Gurion and the Declaration of Independence

As the British prepared to lower their flag and leave Palestine on May 14, 1948, the Jewish leadership debated what to do. The State Department in Washington, reversing earlier US support for partition, proposed a UN trusteeship as a way of preventing the war that everyone could see coming. Truman was ambivalent. Ben-Gurion was not.

David Ben-Gurion, born David Grün in Plonsk, Russian Poland, in 1886, had been a committed Zionist since his youth and had arrived in Palestine in 1906 as a Second Aliyah immigrant. He had spent four decades building the institutions of the Yishuv (the Jewish community in pre-state Palestine), navigating the complex politics of the Zionist movement, fighting the British, and preparing for the moment that was now at hand. He was sixty-one years old, stocky and balding, with tufts of white hair on the sides of his head. He was arguably the most consequential political figure in the history of Zionism, a man of iron will, enormous intelligence, and the ruthlessness that the moment required.

Ben-Gurion convened the People's Administration, the Yishuv's provisional government, to vote on whether to declare independence. The debate was intense: some members argued that the military situation was too precarious — with the Arab states' armies preparing to invade — and that it would be better to wait for a ceasefire. Ben-Gurion insisted that the moment was now or never. He won the vote eleven to two.

At four o'clock in the afternoon of Friday, May 14, 1948, in the Tel Aviv Museum of Art (now Independence Hall) on Rothschild Boulevard, David Ben-Gurion rose at a lectern beneath a large portrait of Theodor Herzl and declared the establishment of the State of Israel. He read the Declaration of Independence, which stated in part: "By virtue of the natural and historic right of the Jewish people and of the Resolution of the United Nations General Assembly, we hereby proclaim the establishment of the Jewish State in Palestine, to be called Israel." The declaration promised full social and political equality for all inhabitants of the state, "irrespective of religion, race or sex," guaranteed freedom of religion and conscience, and "extend[ed] the hand of peace and good-neighborliness to all the states around us and to their peoples, and invite[d] them to cooperate with the independent Jewish nation for the common good of all."

Two hundred and fifty people attended the ceremony. The speech lasted seventeen minutes. When it was finished, the orchestra played "Hatikvah," and the crowd wept.

Eleven minutes after Ben-Gurion finished speaking, the White House switchboard put through recognition of the new state. Harry Truman, over the strong objections of Secretary of State George Marshall and much of the foreign policy establishment, had decided to extend de facto recognition to Israel immediately. He wrote in his diary that night: "I had faith in Israel before it was established." The Soviet Union extended recognition two days later. De jure recognition from the United States came later in January 1949. Israel had been born.

The First Arab-Israeli War: May 1948 to July 1949

At midnight on May 14 to 15, 1948 — the moment the British Mandate officially expired — armies from Egypt, Transjordan, Syria, Iraq, and Lebanon crossed into the territory of former Mandatory Palestine. Saudi Arabia also sent a small contingent, and Yemen declared its support. The Arab states justified their intervention as a defense of the Palestinian Arab population and a resistance to what they characterized as the illegal Zionist seizure of Arab land.

The forces that crossed the borders were not the overwhelming juggernaut of Arab League propaganda. Egypt sent approximately ten thousand troops, organized into three brigades, with armor and artillery. The Arab Legion of Transjordan — the best-trained and most effective Arab force, trained and officered partly by British officers including its commander, John Bagot Glubb — numbered about four thousand five hundred. Syria, Iraq, and Lebanon added smaller contingents. The total Arab force at the outset was perhaps twenty-four thousand to twenty-eight thousand soldiers in regular units, supplemented by Palestinian irregulars and the Arab Liberation Army.

Against this, Israel had the Haganah — some thirty-five thousand fighters — supplemented by the Irgun and Lehi, with a total mobilizable force of perhaps sixty thousand. Israel was significantly outgunned at the start: the Arab armies had tanks, heavy artillery, and air forces; Israel had none. But this disparity narrowed rapidly as Israel's procurement efforts, particularly the Czech arms deal, began to bear fruit.

The first weeks of the war were desperate for Israel. Egyptian forces advanced rapidly from the south, reaching within twenty miles of Tel Aviv before being halted. The Arab Legion captured the Jewish Quarter of Jerusalem's Old City. Syrian forces attacked in the north. Israeli defenders at the Degania kibbutzim in the Jordan Valley repulsed a Syrian tank assault with Molotov cocktails and a single cannon improvised from a drainage pipe, in a defensive success that became legendary in Israeli military history.

On June 11, a UN-mediated ceasefire took effect. This first truce lasted four weeks, and both sides used it to regroup, re-arm, and reinforce. Israel used the ceasefire to absorb massive arms shipments from Czechoslovakia — which, alone among the world's nations, was willing to sell arms to the new state. The Czech deal, negotiated by Israeli agents in Prague with the knowledge of the Soviet Union (which saw an opportunity to embarrass the British), brought a crucial shipment of rifles, machine guns, artillery pieces, and most importantly, ten Avia S-199 fighter aircraft — Czechoslovakian-built aircraft using the airframe of the German Messerschmitt Bf 109 with a different, unsuitable engine that made them viciously difficult to fly, but which nonetheless gave Israel its first air force. On the first day of Israeli air operations, four S-199s attacked an Egyptian column advancing on Tel Aviv, breaking up the advance and demonstrating for the first time that Israel could contest the skies.

When fighting resumed in July, Israel went on the offensive on all fronts with new confidence and new weapons. The IDF — formally created on May 26, 1948, unifying the Haganah, Irgun, and Palmach under a single command structure — conducted a series of major operations that dramatically expanded Israeli-controlled territory.

The Battle for Jerusalem

No city in Palestine was more fiercely contested than Jerusalem, holy to three world religions and the emotional and symbolic heart of both Zionist and Palestinian aspirations. The battle for Jerusalem in 1948 was not a single engagement but a months-long siege punctuated by desperate set-piece battles.

The Arab Legion of Transjordan, commanded by Glubb Pasha and his British-trained officers, was tasked with capturing the Jewish-held areas of Jerusalem and securing the entire West Bank for Transjordan. The Legion's central role in Jerusalem gave the battle for the city an international dimension: British officers of a Commonwealth army were, in effect, fighting a war against a state that the United States and Soviet Union had recognized.

The fall of the Jewish Quarter of Jerusalem's Old City on May 28, 1948, was one of the most dramatic moments of the war. Approximately two thousand Jews lived in the Jewish Quarter, a warren of narrow streets surrounding the sites of the ancient Temple Mount neighborhood. Defending it were approximately three hundred Haganah fighters and local residents. After days of intense fighting against the Arab Legion's superior firepower, the defenders — out of ammunition, with dozens dead and hundreds wounded — surrendered. The aged rabbis who led the community walked out under a white flag. Jewish residents were evacuated; the Jewish Quarter's buildings were systematically destroyed by the Arab Legion, including the magnificent Hurva Synagogue, the spiritual center of Jerusalem's Jewish community, which was blown up on May 28, 1948. The ruins of the Hurva (rebuilt and rededicated in 2010) became a symbol of what Jews had lost and what they vowed to recover.

On the road to Jerusalem, the battle for the hilltop positions guarding the approaches to the city was savage. The Kastel, a ruined Crusader fortress controlling the Jerusalem road, changed hands multiple times in fierce fighting; its Arab commander Abd al-Qadir al-Husseini was killed there on April 8, depriving the Palestinian Arab forces of their most effective and charismatic military leader. Israeli forces eventually secured the heights overlooking the road.

With the fall of the Jewish Quarter and the continuation of the Arab Legion's siege of Jewish Jerusalem, the city's Jewish population faced potential starvation and military collapse. The Haganah's solution was audacious: the construction of an entirely new road — the "Burma Road" — through the rocky hillsides south of the main highway, bypassing Arab Legion positions. Built at night under fire in a matter of weeks using bulldozers and manual labor, the Burma Road enabled the first convoys of supplies to reach Jerusalem in late June, saving the city.

Operation Dani and the Lydda Death March

Operation Dani, launched on July 9, 1948, during the brief interval between the first truce and the second, was Israel's largest single military operation and resulted in one of the 1948 war's most controversial episodes: the expulsion of the populations of Lydda (Lod) and Ramle, two major Arab cities near Tel Aviv's eastern approaches.

Lydda and Ramle together had Arab populations of approximately fifty thousand to seventy thousand people. They sat astride the central road and railway line, and their continued Arab control threatened Israeli communications between Tel Aviv and Jerusalem. Israeli forces, commanded by a young Palmach officer named Yigal Allon (with his subordinate commander Yitzhak Rabin, the future prime minister), captured both cities rapidly. The question of what to do with the civilian populations was referred to Ben-Gurion. According to Rabin's own account — excised from his memoirs by Israeli military censors in 1979 but eventually published in 1987 — Ben-Gurion, when asked what to do with the inhabitants of Lydda, made a dismissive, go-ahead gesture with his hands and said "drive them out" (or words to that effect; the precise phrase was disputed).

Approximately fifty thousand to seventy thousand people were expelled from Lydda and Ramle on foot in July 1948, in temperatures exceeding forty degrees Celsius. They walked eastward through the hills toward Jordanian lines, a distance of between fifteen and thirty kilometers. The path became known as the "Lydda Death March." People collapsed from heat, exhaustion, and dehydration. Pregnant women went into labor by the roadside. How many died is disputed: estimates range from dozens to several hundred. The refugees left behind everything they owned. The towns were then repopulated with Jewish immigrants.

The expulsion from Lydda and Ramle was one of the clearest cases in the 1948 war of an explicit Israeli military order to expel a civilian population, and it was carried out by officers who would go on to be among the most celebrated figures in Israeli history — Allon became a major politician and Rabin was twice prime minister and a Nobel Peace Prize laureate. The episode remained largely unknown to the Israeli public until Benny Morris published his research in the late 1980s.

The Arms Embargo and the Czechoslovak Weapons Deal

From the moment the first Arab-Israeli violence broke out, the United States and Britain imposed an arms embargo on both sides. The embargo fell with vastly different weight on the opposing parties. The Arab states were able to draw on their existing arsenals of British weapons and, in Egypt's and Transjordan's cases, on the continued presence of British officers and training. Israel had no existing arsenal at all.

Israel's desperate search for weapons in the first months of 1948 constituted one of the most remarkable procurement operations in military history. Israeli agents fanned out across Europe and North America, buying surplus World War II equipment wherever it could be found — rifles in Belgium, machine guns in Czechoslovakia, artillery pieces in France, landing craft in Italy — and shipping it under fraudulent documentation to destinations in Europe before transshipment to Palestine. The heart of the procurement network was the Czech deal.

Czechoslovakia in 1948 was governed by a communist government installed following a Soviet-backed coup in February 1948. The Soviet Union's strategic calculus at the time favored Israeli success: a new state that drove the British out of Palestine would weaken British influence in the Middle East, a Soviet foreign policy objective. The Czechs accordingly agreed to sell Israel substantial quantities of weapons, including twenty-five thousand rifles, five thousand light machine guns, fifty million rounds of ammunition, and eventually the S-199 aircraft. The weapons were flown and shipped to Israel by an improvised Israeli airlift operation using a mixture of Israeli and non-Israeli pilots, many of them volunteers from the United States and other countries.

The Czech weapons were decisive in the early weeks of the war, transforming Israel from a force that was running out of ammunition to one that could sustain extended offensive operations. Without them, it is very possible that the first Arab-Israeli war would have ended very differently.

The Assassination of Count Folke Bernadotte

On September 17, 1948, in a convoy moving through the Katamon neighborhood of Jewish Jerusalem, UN Mediator Count Folke Bernadotte of Sweden was shot dead by Lehi gunmen at a Jewish Army checkpoint. A French officer in his party, Colonel André Serot, was also killed.

Bernadotte was one of the most distinguished humanitarian figures of the wartime generation. As head of the Swedish Red Cross, he had negotiated the rescue of fifteen thousand concentration camp survivors from the Nazis in the final weeks of World War II (the "White Buses" operation). Appointed as UN Mediator for Palestine in May 1948, he had successfully negotiated both of the war's truces and had proposed a revised partition plan that would have given the Negev to Transjordan and the Galilee to Israel — a plan that both sides rejected for opposite reasons.

Bernadotte was killed by a four-man Lehi squad acting on orders from the Lehi leadership, which included Yitzhak Shamir. The motivation was Bernadotte's revised partition plan, which Lehi believed threatened Israeli control of the Negev and — critically — did not include the return of Jerusalem's Jewish Quarter, which had fallen to the Arab Legion. The assassination shocked the world and shocked much of the Israeli public.

Ben-Gurion used the assassination as an opportunity to move decisively against Lehi. The organization was declared illegal; its members were arrested en masse; its weapons were confiscated. The Irgun had already been forcibly merged into the IDF following the "Altalena Affair" of June 1948, in which an Irgun weapons ship was shelled and sunk by the IDF on Ben-Gurion's orders after the Irgun refused to hand its weapons over to the state — a dramatic and bloody demonstration of Ben-Gurion's determination that the state would have a monopoly on military force. By autumn 1948, the Israeli government had effectively ended the era of competing Jewish underground organizations.

Count Bernadotte's assassination remains a stain on Israel's founding, acknowledged uncomfortably in Israeli historical discourse. Yitzhak Shamir, who rose to be prime minister of Israel in 1983 and 1986, was the Lehi operations chief responsible for the assassination. He never expressed remorse.

The Armistice Agreements of 1949

The 1948 Arab-Israeli War did not end with a peace treaty but with a series of armistice agreements negotiated under UN auspices. The armistices were arranged sequentially:

Egypt signed an armistice with Israel on February 24, 1949, the first and in many ways most important of the agreements. Under it, Egypt retained control of the Gaza Strip — a narrow coastal enclave along the southern Mediterranean coast — which it administered but did not annex, and withdrew from the rest of the Negev desert, which passed under Israeli control. Egypt did not recognize Israel.

Lebanon signed on March 23, 1949. The armistice line between Israel and Lebanon followed the old international boundary almost exactly. Lebanon had played the smallest role of the Arab states in the actual fighting and was quick to reach terms.

Transjordan signed on April 3, 1949. The armistice gave Transjordan control of the West Bank (the highlands of Judea and Samaria) and the eastern part of Jerusalem, including the Old City and its Jewish Quarter. The Old City's Jewish population had been expelled; King Abdullah of Transjordan formally annexed the West Bank and East Jerusalem in April 1950, renaming his kingdom Jordan (the annexation was recognized only by Britain and Pakistan). Abdullah was assassinated on July 20, 1951, at the Al-Aqsa Mosque by a Palestinian Arab nationalist who feared he was about to make peace with Israel.

Syria signed on July 20, 1949, the last of the armistice agreements. Syria retained a series of demilitarized zones in the Jordan Valley, which became a source of continued friction in the 1950s. A Syrian military coup two months before the armistice, on March 30, 1949 — the first of many such coups in Syria — illustrated how the war had destabilized Syrian politics.

No peace treaty followed any of these armistice agreements. The armistices were expressly stated to be military arrangements, not political settlements. The Arab states refused to negotiate any recognition of Israel. The "no peace, no recognition" posture of the Arab states would persist until Egypt's Anwar Sadat became the first Arab leader to visit Israel in November 1977 and the two countries signed a peace treaty in March 1979.

Israel's territory at the end of the armistice agreements was approximately 78 percent of Mandatory Palestine — about 20 percent more than the UN Partition Plan had allocated to the Jewish state. This additional territory, conquered in the course of the war, included the western Galilee, the coastal plain south of Tel Aviv, and parts of the Negev. The West Bank and Gaza remained under Jordanian and Egyptian control respectively, not incorporated into Israel.

The Palestinian Nakba: the Catastrophe

For the Palestinian Arab population, the 1948 war was a catastrophe of civilizational scale, and they named it accordingly. Al-Nakba — "the catastrophe" in Arabic — refers to the displacement of approximately seven hundred thousand to seven hundred and fifty thousand Palestinian Arabs, the destruction of over four hundred Palestinian villages, and the permanent transformation of the Palestinian presence in their homeland.

Before the war, Palestinian Arabs constituted approximately two-thirds of the population of Mandatory Palestine, roughly 1.3 million people. By the end of 1948, some seven hundred thousand to seven hundred and fifty thousand of them were refugees — no longer present in what was now Israel. They had become displaced persons in the surrounding countries (Jordan, Lebanon, Syria, Egypt), in the West Bank and Gaza, or in the parts of Palestine still under Arab control.

How did this happen? The historical debate about the causes of the Palestinian refugee exodus is complex and has been the subject of exhaustive research. Several factors clearly operated:

Palestinian flight driven by fear, beginning with early fighting and accelerating dramatically after Deir Yassin: the news of massacres, real and rumored, spread through Palestinian communities and produced panic flight. Many Palestinians expected to return after the Arab armies had won the war — a return that never came.

Explicit expulsions by Israeli forces: the cases of Lydda and Ramle are documented. Numerous other villages were explicitly ordered evacuated by Israeli military commanders under Plan Dalet's provisions. The newly declassified Israeli military archives documented by Benny Morris in "The Birth of the Palestinian Refugee Problem, 1947-1949" (1988, substantially revised in 2004) show that in many, though not all, cases of Palestinian depopulation, Israeli military forces played an active role in expelling or terrorizing the population.

Encouragement to leave from Arab leaders: the Israeli narrative traditionally emphasized this factor — that Arab governments told Palestinians to leave to clear the way for the invading armies. The historical evidence for widespread, systematic directives from Arab governments is thin. There were certainly individual instances of this, but it was not the primary or predominant cause of the refugee exodus.

The abandonment of villages after their male inhabitants fled or were killed: in many cases, once the men were captured or fled, the women, children, and elderly remaining in villages left because they had no means of defense or livelihood.

The total number of Palestinian villages depopulated during the 1948 war is estimated at approximately four hundred and eighteen to four hundred and thirty, depending on what is counted as a "village" and how the boundaries of the conflict are drawn. Some were destroyed; others were repopulated with Jewish immigrants; others fell into ruin. The village names were in many cases replaced with new Hebrew names, and Israeli roads and national parks were built over many former village sites in subsequent decades.

The refugees became one of the most politicized and contested refugee populations in history. In 1949 the United Nations Relief and Works Agency for Palestine Refugees (UNRWA) was established specifically to provide services to Palestinian refugees and their descendants — a mandate unlike that of any other UN refugee agency, reflecting the expectation that the refugee problem would be resolved politically and quickly. It was not. By 2026, the Palestinian refugee population and their descendants number approximately six million people registered with UNRWA, the largest long-running refugee population in the world.

The right of Palestinian refugees to return to their original homes — UN General Assembly Resolution 194, passed in December 1948, stated that "refugees wishing to return to their homes and live at peace with their neighbours should be permitted to do so at the earliest practicable date" — has been a core Palestinian demand in every peace negotiation since 1948 and has been consistently rejected by Israel, which argues that implementing a full right of return would end Israel's existence as a Jewish-majority state.

The 1949 Armistice Lines and the Green Line

The borders of Israel at the end of the 1948 war were defined not by the UN Partition Plan but by where the fighting had stopped and the armistice agreements had drawn the lines. These borders — called the "Green Line" (a term derived from the green ink used to mark them on maps during the armistice negotiations) or the 1949 Armistice Lines — became the internationally recognized boundaries of Israel until 1967.

The Green Line did not correspond to the biblical Land of Israel, nor to the UN Partition Plan's allocation. It incorporated more territory than the Partition Plan had allocated to the Jewish state, including the western Galilee (which had been allocated to the Arab state) and a larger share of the Negev. But it left outside Israeli control the West Bank, East Jerusalem, and the Gaza Strip.

The legal status of the Green Line became one of the central issues of international diplomacy after 1967, when Israel conquered the West Bank and Gaza in the Six-Day War. Since 1967, the international community has generally regarded the Green Line as the boundary between Israel and the occupied Palestinian territories, though Israel has never accepted this characterization for East Jerusalem and has disputed it for the West Bank.

Israel's Admission to the United Nations

Israel applied for UN membership on November 29, 1948 — precisely one year after the UN vote on the Partition Plan. The first application failed: a US veto in the Security Council, reflecting State Department reluctance rather than Truman's personal view. Israel reapplied in March 1949. This time the application succeeded: the Security Council recommended admission on March 4, 1949, and the General Assembly admitted Israel to the United Nations as its fifty-ninth member state on May 11, 1949.

The admission came one year and three days after independence. It represented the formal recognition by the international community of Israel's legitimacy as a sovereign state. For the Zionist movement, it was the culmination of the political program laid out by Theodor Herzl at Basel fifty-two years before: a Jewish state "secured by public law."

The Early Years of the State of Israel

The newborn state faced challenges that would have overwhelmed a less determined society. Its army was exhausted and only partially demobilized. Its economy was shattered by the cost of the war. Its population was a fraction of what it needed to be to defend and populate a country of its size. And it was surrounded by Arab states that formally refused to recognize it and had announced their intention to reverse the results of the war at the first opportunity.

The most urgent challenge was immigration — the Jewish people's ancient yearning to return to their homeland now manifested as a practical state imperative. Within weeks of independence, the Knesset (Israel's parliament) passed the Law of Return (July 1950), which established the right of every Jew in the world to immigrate to Israel and receive citizenship — the founding principle of the Jewish state, the direct legislative answer to the 1939 White Paper and the closed doors of 1938 to 1945.

The immigration that followed was massive and transformative. In the first three years of independence, the Jewish population of Israel roughly doubled. The new immigrants came in two main waves with very different characters.

The first wave was the European survivors — Holocaust survivors from the displaced persons camps of Europe, and refugees from Eastern Europe where Soviet-dominated governments had crushed Jewish communal life. These were people who had endured unimaginable suffering and arrived in their new homeland with little more than the clothing on their backs and a desperate need for security. Many were physically ill; many were psychologically traumatized; almost all had lost family members to the camps.

The second wave, and in some ways the more numerically significant, came from the Jewish communities of the Arab world — the Mizrahi Jews (from the Hebrew word for "eastern"). Before 1948, approximately 850,000 Jews lived in Arab countries: Iraq, Egypt, Syria, Yemen, Libya, Morocco, Tunisia, Algeria. The establishment of Israel and the 1948 war transformed their position catastrophically. The Arab defeat in 1948 unleashed a wave of anti-Jewish violence, legal discrimination, property confiscation, and persecution across the Arab world. In Iraq, the legal status of Jews was revoked; in Libya, Jews were attacked in pogroms; in Egypt, Jewish businesses were sequestered and Jews expelled. The ancient Jewish communities of the Arab world, some of which had existed for more than two thousand years predating the Arab conquest of their countries, were effectively destroyed in a generation. Between 1948 and the early 1970s, approximately 850,000 Mizrahi Jews fled or were expelled from Arab countries. Most came to Israel.

The new immigrants — European and Middle Eastern, Ashkenazi and Mizrahi, secular and religious, socialist and conservative — were housed initially in ma'abarot, a word usually translated as "transit camps" but which were in practice vast tent cities and corrugated-iron shanty towns strung along roadsides and in the open desert, where families lived in cramped conditions for months or years while permanent housing was built. The ma'abarot were a notorious aspect of early Israeli life: they combined genuine if rudimentary material provision with a social and cultural violence done to the Mizrahi immigrants in particular, who were subjected to medical treatments (including mandatory fumigation with DDT) and cultural erasure that reflected the Ashkenazi-dominated establishment's condescension toward Middle Eastern Jewish culture.

The economic situation was dire. Israel's first decade was characterized by severe austerity: food, fuel, clothing, and most consumer goods were rationed. The government financed itself partly through West German reparations (the Luxembourg Agreement of 1952, deeply controversial within Israel, in which West Germany paid Israel DM 3 billion as restitution for the Holocaust — money that proved crucial to Israeli economic development), partly through American Jewish philanthropy, and partly through US government loans. The standard of living was austere but improving steadily.

The Historical Debate: New Historians and Revisionism

For the first four decades of Israel's existence, the official narrative of the 1948 war was largely the one propagated by Israeli government sources and popular Zionist historians: Israel had fought a defensive war against Arab aggression; Palestinian Arabs had fled voluntarily, urged by their leaders; the Deir Yassin massacre was an aberration committed by extremists; and Israel had accepted partition while the Arabs had rejected it and chosen war.

This official narrative began to crack in the mid-1980s, when Israel's state archives and military archives began releasing documents from the 1948 period under the country's thirty-year declassification rule. A generation of Israeli historians who approached these documents with scholarly detachment and without the ideological investments of the founding generation began to produce a very different account of events.

Benny Morris, a journalist-turned-historian, published "The Birth of the Palestinian Refugee Problem, 1947-1949" in 1988, a painstaking examination of the documentary record of Palestinian displacement. Morris found extensive evidence of Israeli military expulsion of Arab civilians, of atrocities beyond Deir Yassin, and of deliberate policy decisions to prevent Palestinian refugees from returning. His work was a devastating challenge to the voluntary-flight narrative. He followed it with "1948: A History of the First Arab-Israeli War" (2008), a comprehensive military history that sought to give a balanced account of both sides' conduct.

Avi Shlaim, an Iraqi-born Israeli historian working at Oxford, examined the secret diplomacy of the 1948 war in "Collusion Across the Jordan" (1988, later republished as "The Politics of Partition"), arguing that King Abdullah of Transjordan and the Zionist leadership had reached a secret understanding before the war that effectively divided Palestine between them, with Abdullah receiving the West Bank in exchange for keeping the Arab Legion out of the territory allocated to Israel by the Partition Plan. This "collusion" narrative implied that the "Arab invasion" of 1948 was not as unitary or as purely hostile as the official Israeli narrative suggested.

Ilan Pappé, the most politically radical of the New Historians, went further than Morris. In "The Ethnic Cleansing of Palestine" (2006), Pappé argued that the Palestinian refugee exodus was not primarily a byproduct of wartime chaos or military necessity but the result of a deliberate plan — which he called Plan Dalet — conceived and executed by the Zionist leadership to ensure an Arab-free Jewish state. Pappé's use of the term "ethnic cleansing" (a term with specific legal and political connotations derived from the Balkan wars of the 1990s) generated enormous controversy; his departure from Israel and his position at the University of Exeter in the UK reflected the hostility that his work generated in the Israeli academic and political establishment.

Importantly, even Benny Morris — the New Historian whose empirical work provided much of the documentary foundation for the revisionist narrative — drew very different political conclusions from his research than Pappé did. In a notorious 2004 interview, Morris stated that Ben-Gurion had been right to "cleanse" the country of Arabs for the sake of Israeli security, and suggested that the "ethnic cleansing" of 1948 had been incomplete — a remark that appalled the Israeli left and the international human rights community. Morris's trajectory from revisionism to hawkishness illustrated how the same historical facts could support very different political conclusions.

The New Historians' work did not go unchallenged. A group of "post-Zionist" and "anti-post-Zionist" historians argued back and forth about methods, sources, and interpretations throughout the 1990s and 2000s. Efraim Karsh, a scholar at King's College London, produced a sustained critique of the New Historians in "Fabricating Israeli History" (1997), arguing that Morris and others had misread or selectively used the documentary evidence. The debate has not been resolved to everyone's satisfaction; it has, however, permanently changed the terrain of historical discussion about 1948, making it impossible for serious historians to simply repeat the official Israeli narrative without engaging with the evidence the New Historians assembled.

Conclusion

The founding of Israel in 1948 was simultaneously one of history's most extraordinary acts of national will and one of its most devastating humanitarian disasters. It was the culmination of fifty years of Zionist political work, the fulfillment of a promise — the Balfour Declaration — that a colonial power had made for its own strategic reasons, and the desperate response of a people who had just lost a third of their number in the most systematic genocide the modern world had ever produced. It was also, for the Palestinian Arab population of Mandatory Palestine, the destruction of a society and the beginning of a displacement whose end is not yet in sight.

The 1948 Arab-Israeli War established the military and political facts on the ground that have defined the conflict ever since. Israel's borders — the Green Line of 1949 — became the internationally recognized framework for negotiation. The Palestinian refugee problem — created when between seven hundred thousand and seven hundred and fifty thousand people fled or were expelled — became the central human tragedy of Middle Eastern politics, unresolved despite decades of diplomacy. The Arab states' refusal to recognize Israel, maintained formally until Egypt broke ranks in 1979, locked the entire region into a state of permanent hostility that consumed enormous resources and human lives in wars in 1956, 1967, 1973, and beyond.

Understanding the founding of Israel and the 1948 war is inseparable from understanding the world we live in today. The question of Palestinian self-determination, the status of Jerusalem, the fate of Palestinian refugees, the borders of any future peace settlement — all have their roots in the decisions made and the violence done in that extraordinary, terrible year of 1948.

The long-tail search terms for this topic — "who founded Israel and when," "what caused the 1948 Arab-Israeli War," "what is the Nakba in Palestinian history," "what did the Balfour Declaration promise," "what happened at Deir Yassin," "who were the New Historians of Israel," "what is Plan Dalet," "how did Israel win the 1948 war," "what were the 1949 armistice lines," "why did Palestinian Arabs flee in 1948," "what is the Law of Return Israel," "who was Theodor Herzl Zionism founder," "what was the UN Partition Plan 1947" — all lead ultimately to the same story: a story that has no clean beginning and no clean ending, only a long middle in which human beings on both sides have paid and continue to pay an enormous price for the ambitions, the fears, and the failures of the generation that made the catastrophic and irreversible choices of 1947 and 1948.
