Ottoman Empire, also known as Turkish Empire or Ottoman Turkey, was an empire founded in the late 13th century in northwestern Anatolia in the vicinity of Bilecik and Söğüt by the Oguz tribal leader Osman I. After 1354, the Ottomans crossed into Europe, and with the conquest of the Balkans the Ottoman Beilhique was transformed into a transcontinental empire. The Ottomans ended the Byzantine Empire with the conquest of Constantinople in 1453 by Muhammad the Conqueror.
During the 16th and 17th centuries, at the height of its power under Suleiman the Magnificent, the Ottoman Empire was a multinational, multilingual empire that controlled much of Southeast Europe, Western Asia, the Caucasus, North Africa and the Horn of Africa.
