Turkey, officially the Republic of Türkiye (Turkish: Türkiye Cumhuriyeti [ˈtyɾcije dʒumˈhuːɾijeti] ^ⓘ), is a country mainly in Anatolia in West Asia, with a smaller part called East Thrace in Southeast Europe. It borders the Black Sea to the north; Georgia, Armenia, Azerbaijan, and Iran to the east; Iraq, Syria, and the Mediterranean Sea and Cyprus to the south; and the Aegean Sea, Greece, and Bulgaria to the west. Turkey is home to over 85 million people; most are ethnic Turks, while ethnic Kurds are the largest ethnic minority. Officially a secular state, Turkey has a Muslim-majority population. Ankara is Turkey's capital and second-largest city; Istanbul is its largest city, and its economic and financial center, as well as the largest city in Europe. Other major cities include İzmir, Bursa, Antalya, Konya and Adana.

Human habitation began in Late Paleolithic. Home to important Neolithic sites like Göbekli Tepe and some of the earliest farming areas, present-day Turkey was inhabited by various ancient peoples. Hattians were assimilated by the incoming Anatolian peoples. Increasing diversity during Classical Anatolia transitioned into cultural Hellenization following the conquests of Alexander the Great; Hellenization continued during the Roman and Byzantine eras. The Seljuk Turks began migrating into Anatolia in the 11th century, starting the Turkification process. The Seljuk Sultanate of Rum ruled Anatolia until the Mongol invasion in 1243, when it disintegrated into Turkish principalities. Beginning in 1299, the Ottomans united the principalities and expanded; Mehmed II conquered Istanbul in 1453. During the reigns of Selim I and Suleiman the Magnificent, the Ottoman Empire became a global power.

From the late 18th century onwards, the empire's power and territory declined; reforms were also made. In the 19th and early 20th centuries, persecution of Muslims during the Ottoman contraction and in the Russian Empire resulted in large-scale loss of life and mass migration into modern-day Turkey from the Balkans, Caucasus, and Crimea. Second Constitutional Era ended with the 1913 coup d'état. Under the control of Three Pashas, the Ottoman Empire entered World War I in 1914. During the war, the Ottoman government committed genocides against its Armenian, Greek and Assyrian subjects. After its defeat, the Ottoman Empire was partitioned. The Turkish War of Independence resulted in the abolition of the sultanate in 1922 and the signing of the Treaty of Lausanne in 1923. The Republic was proclaimed on 29 October 1923, modelled on the reforms initiated by the country's first president, Mustafa Kemal Atatürk.
