Republic of Turkey

The occupation of Constantinople and Smyrna by the Allies in the aftermath of World War I prompted the establishment of the Turkish national movement.Under the leadership of Mustafa Kemal Pasha, a military commander who had distinguished himself during the Battle of Gallipoli, the Turkish War of Independence was waged with the aim of revoking the terms of the Treaty of Sèvres.
By 18 September 1922, the occupying armies were expelled, and the Ankara-based Turkish regime, which declared itself the legitimate government of the country in April 1920, started to formalise the legal transition from the old Ottoman into the new Republican political system. On 1 November, the newly founded parliament formally abolished the Sultanate, thus ending 623 years of Ottoman rule. The Treaty of Lausanne of 24 July 1923 led to the international recognition of the sovereignty of the newly formed "Republic of Turkey" as the continuing state of the Ottoman Empire, and the republic was officially proclaimed on 29 October 1923 in Ankara, the country's new capital.The Lausanne treaty stipulated a population exchange between Greece and Turkey, whereby 1.1 million Greeks left Turkey for Greece in exchange for 380,000 Muslims transferred from Greece to Turkey.

Mustafa Kemal became the republic's first President and subsequently introduced many radical reforms with the aim of transforming old Ottoman-Turkish state into a new secular republic.With the Surname Law of 1934, the Turkish Parliament bestowed upon Mustafa Kemal the honorific surname "Atatürk" (Father of the Turks.)

Turkey remained neutral during most of World War II, but entered the war on the side of the Allies on 23 February 1945, as a ceremonial gesture. On 26 June 1945, Turkey became a charter member of the United Nations.Difficulties faced by Greece after the war in quelling a communist rebellion, along with demands by the Soviet Union for military bases in the Turkish Straits, prompted the United States to declare the Truman Doctrine in 1947. The doctrine enunciated American intentions to guarantee the security of Turkey and Greece, and resulted in large-scale U.S. military and economic support.Both countries were included in the Marshall Plan and OEEC for rebuilding European economies in 1948, and subsequently became founding members of the OECD in 1961.
After participating with the United Nations forces in the Korean War, Turkey joined NATO in 1952, becoming a bulwark against Soviet expansion into the Mediterranean. Following a decade of Cypriot intercommunal violence and the coup in Cyprus on 15 July 1974 staged by the EOKA B paramilitary organization, which overthrew President Makarios and installed the pro-Enosis (union with Greece) Nikos Sampson as dictator, Turkey invaded Cyprus on 20 July 1974.Nine years later the Turkish Republic of Northern Cyprus, which is recognized only by Turkey, was established.
The single-party period ended in 1945. It was followed by a tumultuous transition to multiparty democracy over the next few decades, which was interrupted by military coups d'état in 1960, 1971, 1980 and 1997.[49][page needed] In 1984, the PKK began an insurgency against the Turkish government; the conflict, which has claimed over 40,000 lives, continues today.Since the liberalisation of the Turkish economy during the 1980s, the country has enjoyed stronger economic growth and greater political stability.
