Turkey is a democratic, secular, unitary, constitutional republic whose political system was established in 1923 under the leadership of Mustafa Kemal Atatürk, following the fall of the Ottoman Empire in the aftermath of World War I.

Since then, Turkey has become increasingly integrated with the West through membership in organizations such as the Council of Europe, NATO, OECD, OSCE and the G-20 major economies. Turkey began full membership negotiations with the European Union in 2005, having been an associate member of the EEC since 1963, and having reached a customs union agreement in 1995.

Meanwhile, Turkey has continued to foster close cultural, political, economic and industrial relations with the Eastern world, particularly with the states of the Middle East and Central Asia, through membership in organizations such as the OIC and ECO. Turkey is classified as a developed country by the CIA and as a regional power  by political scientists and economists worldwide
