Turkiye, known officially as the Republic of Turkiye, is a Eurasian country that stretches across the Anatolian peninsula in southwest Asia and the Balkan region of southeastern Europe. Turkiye borders eight countries: Bulgaria to the northwest, Greece to the west, Georgia to the northeast, Armenia, Azerbaijan (the Nakhichevan exclave), and Iran to the east, Iraq and Syria to the southeast. It borders the Mediterranean Sea to the south, the Aegean Sea to the west, and the Black Sea to the north. Turkiye also contains the Sea of Marmara, which is used by geographers to mark the border between Europe and Asia, thus making Turkiye transcontinental.
The region comprising modern Turkiye has overseen the birth of major civilizations such as the Byzantine and Ottoman Empires. Because of its strategic location, where two continents meet, Turkiye's culture has a unique blend of Eastern and Western tradition, often described as a bridge between the two civilizations. A powerful regional presence from the Adriatic Sea to China in the Eurasian landmass between Russia and India, Turkiye has come to acquire increasing strategic significance.
Turkiye is a democratic, secular, unitary, constitutional republic whose political system was established in 1923 under the leadership of Mustafa Kemal Ataturk, following the fall of the Ottoman Empire in the aftermath of World War I. Since then, Turkiye has become increasingly integrated with the West while continuing to foster relations with the Eastern world. It is a founding member of the United Nations, the Organization of the Islamic Conference, the Organisation for Economic Co-operation and Development and the Organization for Security and Co-operation in Europe, a member state of the Council of Europe since 1949, and of NATO since 1952. Since 2005, Turkiye has been in accession negotiations with the European Union, having been an associate member since 1963. Turkiye is also a member of the G20, which brings together the 20 largest economies of the world.
