The Ottoman Empire (Ottoman Turkish: دَوْلَتِ عَلِيّهٔ عُثمَانِیّه Devlet-i Aliyye-i Osmâniyye, Modern Turkish: Osmanlı İmparatorluğu), also historically referred to as the Turkish Empire or Turkey, was an Islamic sultanate and later a caliphate founded by Oghuz Turks under Osman Bey in northwestern Anatolia in 1299. With conquests in the Balkans by Murad I between 1365 and 1389, and the conquest of Constantinople by Mehmed II in 1453, the Ottoman sultanate was transformed into an empire.
During the 16th and 17th centuries, in particular at the height of its power under the reign of Suleiman the Magnificent, the Ottoman Empire was a powerful multinational, multilingual empire controlling much of Southeast Europe, Western Asia, the Caucasus, North Africa, and the Horn of Africa. At the beginning of the 17th century the empire contained 32 provinces and numerous vassal states. Some of these were later absorbed into the empire, while others were granted various types of autonomy during the course of centuries.
With Constantinople as its capital and control of lands around the Mediterranean basin, the Ottoman Empire was at the centre of interactions between the Eastern and Western worlds for six centuries. Following a long period of military setbacks against European powers and gradual decline, the empire collapsed and was dissolved in the aftermath of World War I, leading to the emergence of the new state of Turkey in the Ottoman Anatolian heartland, as well as the creation of modern Balkan and Middle Eastern states
