Overview

Tsarevets Hill in Veliko Turnovo, capital of the Second Bulgarian Empire THE HISTORY OF THE LAND now known as Bulgaria has been determined by its location between Asia and Europe, by its proximity to powerful states competing for land and influence at the junction of trade routes and strategic military positions, and by the strong national territorial drive of various Bulgarian states. Before the Christian era, Greece and Rome conquered the region and left substantial imprints on the culture of the people they found there. The Bulgar tribes, who arrived in the seventh century from west of the Urals, have occupied the region continuously for thirteen centuries. Over time Bulgarian culture merged with that of the more numerous Slavs, who had preceded the Bulgars by one century. After converting to Christianity and adopting a Slavic language in the ninth century, the Bulgarians consolidated a distinct Slavic culture that subsequently passed through periods of both expansionist independence and subordination to outside political systems. From the ninth until the fourteenth century, Bulgaria was a dominant force in the Balkans because of its aggressive military tradition and strong sense of national identity. The chief rival and neighbor, the Byzantine Empire, left a lasting political imprint on two Bulgarian empires as it competed with them for regional domination. Marking the deterioration of both the Byzantine and the Bulgarian political structures, the fall of Constantinople to the Ottoman Turks in 1453 began four centuries of Turkish suppression of Bulgarian cultural and political institutions. By the eighteenth century, however, weakening Ottoman control allowed a Bulgarian cultural revival. In the next century, Western political ideas gradually combined with the reborn Bulgarian national consciousness to form an independence movement. The movement was complicated by internal disagreement on aims and methods, the increasing weakness of the Ottoman foothold in Europe, and the conflicting attitudes of the major European powers toward Bulgaria. Russia gained distinction as Bulgaria’s protector by driving out the Turks in 1877, but France and Britain curbed Russian power in the Balkans by forcing establishment of a limited autonomous Bulgarian state under Turkish rule. The instrument of that limitation, the Treaty of Berlin, revived longstanding Bulgarian territorial frustrations by placing the critical regions of Macedonia and Thrace beyond Bulgarian control. Both of those disputed regions had substantial Bulgarian populations. During the next sixty years, Bulgaria would fight unsuccessfully in four wars, in a variety of alliances, to redress the grievance. None of the four wars brought substantial new territory to Bulgaria. Beginning in 1878, Bulgaria was nominally ruled by members of West European royal houses under a parliamentary form of government. Prime Minister Stefan Stambolov unified the country during its first decade, but extremist political parties exerted substantial influence from the beginning. Between 1878 and the declaration of full independence in 1908, Bulgaria passed through a period of peaceful modernization with expansion in industry, science, education, and the arts. Modernization and industrialization sowed the seeds of class conflict, however, nurturing strong socialist and agrarian opposition parties in the decades that followed independence. The period between 1912 and 1944 was full of irredentist wars and internal political turmoil. By 1900 Serbia and Greece were the major territorial rivals, but a World War I alliance with Germany gained Bulgaria little advantage over them. After the war, the agrarian reform government of Aleksandur Stamboliiski had failed to unite the country by 1923. The series of unstable factions and forms of government that followed Stamboliiski was broken only by Bulgaria’s participation as an Axis ally in World War II. Again no territory was gained, but World War II brought Soviet occupation, the end of the monarchy, and forty-one years of unbroken communist rule beginning in 1948. During that entire period, Bulgaria was the closest East European imitator of Soviet internal and foreign policy. The years 1948 through 1989 were a time of collectivization, heavy industrialization, drastic restriction of human rights, and close adherence to Soviet Cold-War policy.

Historical Eras

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

  1. Antiquity & Early Peoples

    1000 BCE – 681

    Thracian tribes inhabited the region for millennia before Greek colonization and later Roman conquest integrated the area into classical Mediterranean civilization. The Romans organized the territory into the provinces of Moesia and Thrace, leaving enduring urban and infrastructural legacies. In the 6th and 7th centuries, Slavic peoples migrated into the Balkans, laying the demographic foundation upon which the Bulgarian state would be built.

  2. First Bulgarian Empire

    681 – 1018

    Khan Asparuh led the Bulgar tribes across the Danube and compelled the Byzantine Empire to recognize the First Bulgarian Empire in 681. Tsar Boris I's adoption of Eastern Orthodox Christianity in 870 and the creation of the Cyrillic alphabet under Saints Cyril and Methodius defined Bulgarian cultural identity. Tsar Simeon I expanded the empire to its greatest extent in the early 10th century, but Byzantine pressure ultimately led to full conquest by Emperor Basil II in 1018.

  3. Second Bulgarian Empire

    1185 – 1396

    The brothers Asen and Peter led a successful uprising against Byzantine rule in 1185, establishing the Second Bulgarian Empire with Veliko Tarnovo as its capital. Under Ivan Asen II (1218–1241) the empire reached its territorial zenith, controlling much of the Balkan Peninsula and becoming a major regional power. Internal fragmentation and mounting pressure from the Mongols and Ottomans eroded Bulgarian strength, and Sofia fell to the Ottoman Turks in 1385, with the empire extinguished by 1396.

  4. Ottoman Rule

    1396 – 1878

    For nearly five centuries, Bulgaria existed under Ottoman administration, with Bulgarian political institutions suppressed and the Orthodox Church subjected to the Greek Patriarchate. By the 18th century a Bulgarian National Revival (Vuzrazhdane) took root, driven by figures such as Paisii Hilendarski, whose 1762 Slavo-Bulgarian History rekindled national consciousness. The April Uprising of 1876 was brutally crushed, provoking international outrage and ultimately Russia's intervention in the Russo-Turkish War of 1877–78, which ended Ottoman rule.

  5. Third Bulgarian State

    1878 – 1946

    The Treaty of Berlin (1878) established an autonomous Bulgarian principality, and full independence was declared under Tsar Ferdinand in 1908. Bulgaria fought in the Balkan Wars (1912–13) and both World Wars in pursuit of territorial ambitions rooted in the unresolved grievances of the Berlin settlement, each time ending on the losing side. Political instability, agrarian unrest, authoritarian rule under Tsar Boris III, and wartime alliance with Nazi Germany set the stage for the communist takeover of 1944–46.

  6. Communist & Modern Era

    1946 – present

    The People's Republic of Bulgaria, dominated by Todor Zhivkov from 1954 to 1989, aligned closely with the Soviet Union and undertook forced collectivization, industrialization, and the suppression of political dissent. The fall of communism in November 1989 opened a turbulent transition to multiparty democracy and a market economy, complicated by inflation, corruption, and organized crime. Bulgaria joined NATO in 2004 and the European Union in 2007, anchoring its post-communist orientation firmly within Western institutions.
