Multi-party period of the Republic of Turkey

The army balked at the government's instrumentalization of it, and on May 27, 1960, General Cemal Gürsel led a military coup d'état removing President Celal Bayar and Prime Minister Menderes. Menderes was executed with 2 ministers. In October 1961, the military junta returned the power to civilians. The political system that emerged in the wake of the 1960 coup was a fractured one, producing a series of unstable government coalitions in parliament. In 1965, however, the Justice Party of Süleyman Demirel won an absolute majority, which it increased in 1969. But there was increasing polarization between the Justice Party on the right and the Republican People's Party of İsmet İnönü and Bülent Ecevit on the left. In 1969, the right-wing Nationalist Movement Party (MHP) was founded by Alparslan Türkeş, a member of the Counter-Guerrilla, the Turkish branch of NATO's stay-behind army. MHP's youth organizations became known as the Grey Wolves.

A memorandum from the military on March 12, 1971 threatened intervention, forcing the Demirel government to resign. After a period of interim government, Bülent Ecevit became Prime Minister and governed in a coalition with the religious National Salvation Party.

The fractured political scene and poor economy led to mounting violence between ultranationalists and communists in the streets of Turkey's cities. The NATO stay-behind army Counter-Guerrilla, related to the National Intelligence Organization (Turkish: Millî İstihbarat Teşkilâtı, MIT) engaged itself in domestic terror and killed hundreds. As in Italy, it engaged itself in a strategy of tension[1] The overall death-toll of the terror of the 1970s in estimated at 5,000, with right-wing and terrorism responsible for the most part. According to statistics published by the British Searchlight magazine, in 1978 there were 3,319 fascist attacks, in which 831 were killed and 3,121 wounded.[2]

In 1974, the Greek military junta supported a coup in Cyprus led by extremist Greek Cypriots who were hostile to President of Cyprus, Archbishop Makarios, for his communist leanings. Prime Minister Bülent Ecevit invaded Cyprus on July 20, 1974 to counter the potential Greek coup.

Out of the rubble of the previous political system came a single-party governance under Turgut Özal's Motherland Party (ANAP), which combined a globally oriented economic program with conservative social values. Under Özal, the economy boomed, converting towns like Gaziantep from small provincial capitals into mid-sized economic boomtowns.

Upon the retirement of President Kenan Evren, the leader of the 1980 coup, Özal was elected President, leaving parliament in the hands of Yıldırım Akbulut, and, in 1991, Mesut Yılmaz. Yılmaz redoubled Turkey's economic profile and renewed its orientation toward Europe. However, political instability followed, as the host of politicians banned from politics during the 1980 coup reentered politics, fracturing the vote, and the Motherland Party became increasingly corrupt. Özal died of a heart attack in 1993, and Süleyman Demirel was elected president.

The 1995 elections brought a short-lived coalition between Yılmaz's Motherland Party and the True Path Party, now with Tansu Çiller at the helm. Çiller then turned to the Welfare Party (RP), headed by Necmettin Erbakan, the former leader of the National Salvation Party, allowing Erbakan to enter the Prime Ministry. In 1997, the military, citing his government's support for religious policies deemed dangerous to Turkey's secular nature, sent a memorandum to Erbakan requesting that he resign, which he did. Shortly thereafter, the RP was banned and reborn as the Virtue Party (FP). A new government was formed by ANAP and Ecevit's Democratic Left Party (DSP) supported from the outside by the center-left Republican People's Party (CHP), led by Deniz Baykal. Under this government, Abdullah Öcalan, the leader of the Kurdish separatist organisation Kurdistan Workers Party (PKK), was captured in 1999 in Kenya. Imprisoned in the prison-island of İmralı in the Marmara Sea, Öcalan was tried for treason and sentenced to death, later commuted to life imprisonment.

The DSP won big in the 1999 elections on the strength of the Öcalan abduction. Second place went, surprisingly, to the Nationalist Movement Party (MHP). These two parties, alongside Yılmaz's ANAP formed a government. The popular perception was that it would fail; these were, after all, the inheritors of the two groups that were fighting so violently in the streets during the 1970s. However, the government was somewhat effective, if not harmonious, bringing about much-needed economic reform, instituting human rights legislation, and bringing Turkey ever closer to the European Union (EU).
