Turkey is a Eurasian country located in Western Asia (mostly in the Anatolian peninsula) and in East Thrace in Southeastern Europe. Turkey is bordered by eight countries: Bulgaria to the northwest; Greece to the west; Georgia to the northeast; Armenia, Azerbaijan (the exclave of Nakhchivan) and Iran to the east; and Iraq and Syria to the southeast. The Mediterranean Sea and Cyprus are to the south; the Aegean Sea is to the west; and the Black Sea is to the north. The Sea of Marmara, the Bosphorus and the Dardanelles (which together form the Turkish Straits) demarcate the boundary between East Thrace and Anatolia; they also separate Europe and Asia.
Turkey is one of the six independent Turkic states. Approximately 70–80% of the population are ethnic Turks. The country's official language is Turkish, which is spoken by approximately 85% of the population as mother tongue. Kurdish and Zazaki languages are spoken by Kurds and Zazas, who together constitute 18–25% of the population. The vast majority of the population is Muslim. Other minorities are thought to make up between 7 and 12% of the population.
Oghuz Turks began migrating into the area now called Turkey (derived from the Medieval Latin Turchia, i.e. "Land of the Turks") in the 11th century. The process was greatly accelerated by the Seljuk victory over the Byzantines at the Battle of Manzikert. Several small beyliks and the Seljuk Sultanate of Rûm ruled Anatolia until the Mongol invasion. Starting from the 13th century, the Ottoman beylik united Anatolia and created an empire encompassing much of Southeastern Europe, Western Asia and North
