Süleyman Demirel, Turkish engineer and politician, 9th President of Turkey (d. 2015)
Süleyman Sami Gündoğdu Demirel (Turkish pronunciation: [sylejˈman dem'iɾæl]; 1 November 1924 – 17 June 2015) was a Turkish politician, engineer, and statesman who served as the 9th President of Turkey from 1993 to 2000. He previously served as the Prime Minister of Turkey seven times between the years 1965 and 1993. He was the leader of the Justice Party (AP) from 1964 to 1980 and the leader of the True Path Party (DYP) from 1987 to 1993.

Having been identified as a potential future Prime Minister by Adnan Menderes, Demirel was elected leader of the Justice Party in 1964 and managed to bring down the government of İsmet İnönü in 1965 despite not being a Member of Parliament. He supported the government of Suat Hayri Ürgüplü until his party won a parliamentary majority in the 1965 general election. He became the first Prime Minister born in the Republic of Turkey. Claiming that his grouping was the successor of the banned Democrat Party, he was re-elected as Prime Minister in 1969 by winning a parliamentary majority for a second time. Despite his economic reforms which stabilised inflation, he resigned as Prime Minister after his budget was blocked by parliament, but formed his third government shortly after. His premiership came to an end following the 1971 Turkish coup d'état.

Demirel was the leader of the opposition from 1971 to 1975 before forming a four-party government known as the First Nationalist Front, which collapsed in 1977. With two other parties, he formed the Second Nationalist Front cabinet in 1977, which collapsed in 1978. Demirel's minority government in 1979 was unable to elect a president in 1980, leading to the 1980 Turkish coup d'état which banned Demirel from politics. In the 1987 constitutional referendum, Demirel regained the right to actively participate in politics and assumed the leadership of the True Path Party. He won the 1991 general election and formed a coalition with the Social Democratic Populist Party (SHP), assuming his fifth and final term as Prime Minister. Following the sudden death of serving President Turgut Özal, Demirel contested the 1993 presidential election and subsequently became the ninth President of Turkey until 2000. With 10 years and 5 months, Demirel's tenure in the prime ministership is the third longest in Turkish history, after İsmet İnönü and Recep Tayyip Erdoğan.
