Ottoman Empire During the 16th and 17th centuries, at the height of its power under the reign of Suleiman the Magnificent, the Ottoman Empire was a multinational, multilingual empire controlling most of Southeast Europe, parts of Central Europe, Western Asia, parts of Eastern Europe and the Caucasus, North Africa, and the Horn of Africa.[12] At the beginning of the 17th century, the empire contained 32 provinces and numerous vassal states. Some of these were later absorbed into the Ottoman Empire, while others were granted various types of autonomy during the course of centuries.[dn 6]
Fall of Constantinople The Fall of Constantinople (Greek: Ἅλωσις τῆς Κωνσταντινουπόλεως, Halōsis tēs Kōnstantinoupoleōs; Turkish: İstanbul'un Fethi Conquest of Istanbul) was the capture of the capital of the Byzantine Empire by an invading army of the Ottoman Empire on 29 May 1453. The Ottomans were commanded by the then 21-year-old Ottoman Sultan Mehmed the Conqueror, who defeated an army commanded by Byzantine Emperor Constantine XI Palaiologos. The conquest of Constantinople followed a 53-day siege that had begun on 6 April 1453.
