Overview

Alexandru Ioan Cuza, prince of the United Principalities of Moldavia and Walachia (1859-66) THE ROMANIAN PEOPLE’S REPUBLIC, later renamed the Socialist Republic of Romania, came into being in 1948 when the country’s communist party, under Gheorghe Gheorghiu-Dej, consolidated its power and promulgated a Soviet-style constitution. Romania, in spite of its fierce prewar anticommunism and long antipathy toward tsarist Russia and the Soviet Union, became one of the first East European states to suffer a Soviet-sponsored communist takeover after World War II. For nearly a decade after the war, Romania obediently followed Moscow’s lead, but in the late 1950s Gheorghiu-Dej defied a Soviet attempt to make his country a "breadbasket" for the East bloc and insisted on continuing his country’s rapid industrial expansion. The Romanian leader also developed an independent foreign policy and launched a campaign promoting Romanian nationalism. Nicolae Ceausescu succeeded Gheorghiu-Dej in 1965 and continued his mentor’s policies. Ceausescu, however, appended to them an extravagant cult of personality that once promoted him as Romania’s "secular god" and heir to the wisdom of Romanian rulers from ages past. Romanians descend from the Dacians, an ancient people who fell under Rome’s dominance in the first century A.D., intermarried with Roman colonists, and adopted elements of Roman culture, including a Vulgar Latin that evolved into today’s Romanian. Barbarian tribes forced the Romans out of Dacia in 271. In the eleventh century the Magyars, the ancestors of today’s Hungarians, settled the mountainous heart of ancient Dacia, Transylvania. Hungarian historians claim that Transylvania was almost uninhabited when the Magyars arrived; Romanians, however, assert that their ancestors remained in Transylvania after Rome’s exodus and that Romanians constitute the region’s aboriginal inhabitants. This disagreement was the germ of a conflict that poisoned relations between Romanians and Hungarians throughout the twentieth century. For thousands of years, Romania suffered from an unfortunate location astride the invasion routes of migrating hordes and the frontiers of ambitious empires that plundered its wealth and enslaved its people. For centuries Transylvania, with its repressed Romanian majority, was a semi-autonomous part of Hungary. Romanians fleeing Transylvania founded the independent principalities of Walachia and Moldavia in the thirteenth and fourteenth centuries. The Ottoman Empire dominated all three regions from the sixteenth to the late seventeenth century, when Austria’s Habsburgs gained full control of Transylvania. Walachia and Moldavia came under Russian protection soon afterward and remained under Russian influence until the Crimean War (1853-56) ended the protectorate. In 1859 Walachia and Moldavia merged to form Romania, and in 1881 its prince renounced Turkish suzerainty and Romania became a kingdom. Austria reunited Transylvania and Hungary in 1867, but the union lasted only until the end of World War I, when Romania acquired Transylvania. World War II brought dismemberment of Greater Romania, and the country sided with Germany hoping to regain its lost territories. In 1943 the Red Army crushed Romanian forces before Stalingrad, and in 1944 Romania’s King Michael overthrew the country’s radical right-wing premier and signed an armistice with the Soviet Union. Moscow forced Michael to appoint a communist sympathizer to lead the government in 1945, and three years later Romania found itself under strict communist control.

Historical Eras

The major periods of {country}’s history at a glance.

  1. Dacian & Roman Era

    700 BCE – 271

    The Dacians, a Thracian people, established a powerful kingdom in the Carpathian-Danubian region before Roman Emperor Trajan conquered Dacia in 106 AD, transforming it into a Roman province. Over roughly 165 years of Roman rule, the indigenous population intermarried with colonists and adopted Latin language and culture, forming the ethnolinguistic foundation of the Romanian people. Roman legions withdrew under Emperor Aurelian in 271, leaving behind a Romanized population amid encroaching barbarian migrations.

  2. Medieval Principalities

    271 – 1859

    Following Rome's withdrawal, successive waves of Goths, Huns, Avars, and Mongols swept through the territory before Romanians established the principalities of Wallachia (c. 1310) and Moldavia (c. 1352). Leaders such as Mircea the Elder, Stephen the Great, and Vlad III ("the Impaler") defended these principalities against Ottoman expansion, though by the sixteenth century both had fallen under Ottoman suzerainty. Transylvania, meanwhile, remained a semi-autonomous principality under Hungarian and later Habsburg dominion, home to a repressed Romanian majority.

  3. United Principalities

    1859 – 1881

    Following the Crimean War, the Congress of Paris (1856) ended direct Russian protection over Wallachia and Moldavia, creating conditions for national unification. In 1859, both principalities elected Alexandru Ioan Cuza as their common prince, effectively merging into a single state under the name Romania. Cuza enacted sweeping reforms including land redistribution and secularization of monastic estates before being forced to abdicate in 1866; his successor, Prince Carol I of the Hohenzollern-Sigmaringen dynasty, steered Romania to full independence, recognized internationally in 1878, and proclaimed a kingdom in 1881.

  4. Kingdom of Romania

    1881 – 1947

    The Romanian Kingdom expanded dramatically after World War I, in which Romania joined the Allies in 1916 and gained Transylvania, Bessarabia, and Bukovina through the 1918 treaties, creating "Greater Romania." The interwar period brought parliamentary instability, rising fascist movements, and King Carol II's royal dictatorship of 1938. Romania entered World War II aligned with the Axis in 1941, suffered catastrophic losses at Stalingrad, and in August 1944 King Michael led a coup that switched the country to the Allied side, only for Soviet occupation to rapidly extinguish the monarchy by 1947.

  5. Communist Romania

    1947 – 1989

    The Romanian People's Republic, proclaimed in 1948 under Gheorghe Gheorghiu-Dej, imposed a Soviet-style constitution and collectivized agriculture while ruthlessly suppressing political opposition. Nicolae Ceaușescu succeeded in 1965 and, while cultivating an independent foreign policy that earned brief Western favour, built a suffocating cult of personality and deployed the Securitate secret police to enforce ideological conformity. Economic austerity programs in the 1980s, driven by Ceaușescu's obsession with repaying foreign debt, produced severe food and energy shortages that fueled mounting popular resentment.

  6. Post-Communist Romania

    1989 – present

    The December 1989 revolution overthrew and executed Ceaușescu, though former communists under Ion Iliescu dominated politics through the early 1990s amid violent suppression of protesters. A centrist coalition swept to power in 1996, accelerating democratic consolidation and market reforms. Romania joined NATO in 2004 and acceded to the European Union in 2007, cementing its integration into Western institutions while continuing to address challenges of corruption, judicial independence, and economic modernization.
