presidential republic with a
diverse cultural heritage.
 Turkey is bordered by eight countries:
Bulgaria to the northwest;
Georgia to the northeast;
Iran to the east;
Syria to the south. The country is encircled by seas on three sides: the
Aegean Sea is to the west, the
Black Sea to the north, and the
Mediterranean Sea to the south. The
Sea of Marmara, and the
Dardanelles, which together form the

The area of Turkey has been inhabited since the
 by various
ancient Anatolian civilisations, as well as
Alexander the Great's
conquest, the area was
Hellenised, a process which continued under the
Roman Empire and its transition into the
Seljuk Turks began migrating into the area in the 11th century, starting the process of
Turkification, which was accelerated by the Seljuk victory over the Byzantines at the
Battle of Manzikert in 1071.
Seljuk Sultanate of Rûm ruled Anatolia until the
Mongol invasion in 1243, when it disintegrated into small
In the mid-14th century the
Ottomans started uniting Anatolia and created an empire encompassing much of Southeast Europe, West Asia and
North Africa, becoming a major power in Eurasia and Africa during the
early modern period. The empire reached the peak of its power in the 16th century, especially during the reign (1520–1566) of
Suleiman the Magnificent. It remained powerful and influential for two more centuries, until important setbacks in the 17th and 18th century forced it to cede strategic territories in Europe, signalling the loss of its former military strength and wealth. After the
1913 Ottoman coup d'état which effectively put the country under the control of the
Three Pashas, the Ottoman Empire
decided to join the
Central Powers during
World War I which were ultimately defeated by the
Allied Powers. During the war, the Ottoman government committed

Pontic Greek citizens.
Following the war, the conglomeration of territories and peoples that formerly comprised the Ottoman Empire was
partitioned into several new states by the Allied Powers.
Turkish War of Independence (1919–1922), initiated by
Mustafa Kemal Atatürk and his colleagues against the occupying
Allies, resulted in the
abolition of monarchy in 1922 and the establishment of the Republic of Turkey in 1923, with Atatürk as its first president.
 Atatürk enacted
numerous reforms, many of which incorporated various aspects of
Western thought, philosophy, and customs into the new form of Turkish government. Included amongst
Atatürk's reforms were various systems of democratic government, a Latin based alphabet for official government use, and an essentially secular basis of government.
Turkey is a charter member of the
UN, an early member of
NATO, and a founding member of the
G-20. After becoming
one of the first members of the
Council of Europe in 1949, Turkey became an
associate member of the
in 1963, joined the
EU Customs Union in 1995 and started
accession negotiations with the
European Union in 2005.
 Turkey's growing economy and diplomatic initiatives have led to its recognition as a
 while its location has given it geopolitical and strategic importance throughout history.
 Turkey's current administration headed by president
Tayyip Erdoğan has reversed many of the earlier reforms, such as
Freedom of the Press, a
Legislative System of Checks and Balances, and a set of standards for secularism in government, as previously enacted by Atatürk.
 Meanwhile the Turkish economy has had several years of significant growth in GDP.
