where was the territory that made up the ottoman empire
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.[14] 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 5]
Fall of Constantinople Ottomans used the Arabic transliteration of the city's name "Kostantiniyye," (القسطنطينية), as can be seen in numerous Ottoman documents. Islambol ( اسلامبول, Full of Islam) or Islambul (find Islam) or Islam(b)ol (old Turkic: be Islam), both in Turkish Language, were folk-etymological adaptations of Istanbul created after the Ottoman conquest of 1453 to express the city's new role as the capital of the Islamic Ottoman Empire. It is first attested shortly after the conquest, and its invention was ascribed by some contemporary writers to Sultan Mehmed II himself.[73]
