Turkey, officially the Republic of Turkey, is a transcontinental country located mainly on the Anatolian peninsula in Western Asia, with a smaller portion on the Balkan peninsula in Southeastern Europe. East Thrace, the part of Turkey in Europe, is separated from Anatolia by the Sea of Marmara, the Bosporus and the Dardanelles. Turkey is bordered by Greece and Bulgaria to its northwest, the Black Sea to its north, Georgia to its northeast, Armenia, the Azerbaijani exclave of Nakhchivan and Iran to its east, Iraq and Syria to its southeast, the Mediterranean Sea to its south, and the Aegean Sea to its west. Istanbul is the largest city in the country while Ankara is the capital. Approximately 70 to 80 per cent of the country's citizens identify as Turkish, while Kurds are the largest minority at anywhere from 15 to 20 percent of the population.
