Kenan Evren was born in Alaşehir, Manisa Province. Evren was of Albanian descent on his father’s side that originated from Preševo, while his mother was from a Bulgarian Turkish background. After going to elementary school and middle school in Manisa, Balıkesir and Istanbul, he attended military high school in Maltepe, Ankara. In 1938, he graduated from army school and in 1949 from military academy as a staff officer.

Evren married Sekine Evren in 1944 and they had three daughters, Şenay, Gülay and Miray. Sekine died in 1982. In 1990, he was awarded the Atatürk International Peace Prize.

From 1958 to 1959, he served in the Turkish Brigade in Korea. In 1964, he was promoted to general. Evren served at various posts as Army Chief. He was the commander of Operation Gladio’s Turkish branch; the Counter-Guerrilla. The Counter-Guerrilla was an anti-communist “stay-behind” guerrilla force set up with the support of NATO. He became Chief of General Staff in March 1978.

After the coup, Kenan Evren was elected as President of Turkey on 7 November 1982 with the 90% approval of the new constitution that was submitted to a controversial referendum, replacing the older constitution which, according to him, had liberties too “luxurious” for Turkey.

A previous attempt in 1996 had already been tracked down when two members of the assassination team spoke on a cellphone eavesdropped by the police, and the Islamic call to prayer (adhan) could be heard during their conversation. Since the timing of the adhan was 4–5 minutes after Istanbul, a point slightly more to the west by that time margin was sought and the team members were caught in Marmaris itself.

In 2004, he revealed that his daughter, Şenay Gürvit, and son-in-law, Erkan Gürvit, are members of the National Intelligence Organization. His daughter presided over the reprisal operations against the militant Armenian organization ASALA.

On 2 August 2006, a reported plan for assassinating Evren was thwarted when two men were apprehended and arrested in Muğla.

Evren was hospitalized for massive gastrointestinal bleeding on 3 August 2009, in Yalıkavak, Bodrum, where his summer house is located. A temporary artificial pacemaker was applied to Evren while in intensive care due to bradycardia. His large intestine was removed a week later at GATA in Istanbul (Gülhane Military Medicine Academy) where he was transferred. He was discharged on 24 September 2009.

On 10 January 2012, Turkish courts decided to press charges against General Kenan Evren and General Tahsin Şahinkaya, former Commander of the Turkish Air Force, for their role in the 1980 coup. Prosecutors sought life sentences against them. The first court hearing of the case was scheduled for 4 April 2012. Both were sentenced to life imprisonment on 18 June 2014 by a court in Ankara. In accordance with Article 30 of the Military Penal Code, Evren and Şahinkaya were demoted to the lowest rank of private.

Evren died at a military hospital in Ankara on 9 May 2015, aged 97. On 12 May, he was buried in the Turkish State Cemetery in Ankara following the funeral service held at Ahmet Hamdi Akseki Mosque. The funeral was attended by his close relatives and military personnel. In protest, political parties sent no representatives to the former president’s funeral. A number of people protested during the religious service in the mosque’s courtyard.
