Ottoman Empire
Former Turkish empire centered in Asia Minor. It was named for Osman I (1259-1326), a Muslim prince in Bithynia who conquered neighboring regions once held by the Seljuq dynasty and founded his own dynasty c. 1300. Ottoman troops first invaded Europe in 1345, sweeping through the Balkans. Though defeated by Timur in 1402, by 1453 the Ottomans, under Muhammad II the Conquerer (1429-1481), had destroyed the Byzantine empire and captured its capital, Constantinople (Istanbul), which henceforth served as the Ottoman capital. Under Selim I (1467-1520) and his son Süleyman I the Magnificent, the Ottoman empire became the largest in the world, Süleyman taking control of Persia, Arabia, Hungary, and the Balkans. By the early 16th century the Ottomans had also defeated the Mamluks in Syria and Egypt; and their navy under Barbarossa soon seized control of much of the Barbary Coast. Beginning with Selim, the Ottoman sultans also held the title of caliph, the spiritual head of Islam. Ottoman power began to decline in the late 16th century with the destruction of the imperial fleet in 1571 at the Battle of Lepanto. Ottoman forces besieged Vienna in 1683; their defeat and subsequent losses led to their relinquishing Hungary in 1699. Continuing corruption and decadence gradually undermined the government. In the 18th century the Russo-Turkish Wars and wars with Austria and Poland further weakened the empire, which in the 19th century came to be called the “sick man of Europe.” Most of its remaining European territory was lost in the Balkan Wars (1912-13). It sided with Germany in World War I; postwar treaties dissolved the empire, and in 1922 the sultanate was abolished by Mustafa Kemal Ataturk, who proclaimed the Republic of Turkey.
