Turkey, officially the Republic of Türkiye, is a country mainly located 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 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, while Istanbul is its largest city and economic and financial center, as well as the largest city in Europe. Other major cities include İzmir, Bursa and Antalya.
Turkey was first inhabited by modern humans during the 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 Anatolian peoples. Classical Anatolia transitioned into cultural Hellenization following the conquests of Alexander the Great; Hellenization continued during the Roman and Byzantine eras.
