Demirel, Süleyman(sülāmän` dĕmĭrĕl`), 1924–2015, Turkish political leader, prime minister and president of Turkey. A successful engineer, he became leader of the Justice party in 1964, deputy prime minister in Feb., 1965, and prime minister in Oct., 1965. His failure to halt civil anarchy in the form of student riots, leftist agitation, and political terrorism forced the resignation of his centrist government in 1971. He again served as prime minister (1975–80) of a coalition government, but in 1980 civil turmoil led to an army coup. Demirel was ousted, detained (1980, 1983), and banned from politics until 1987. From 1991 to 1993 (now as leader of the conservative True Path party) he was again prime minister, after which he became (1993–2000) president. Although the presidency was largely a ceremonial office, a series of short-lived and unstable governments enabled Demirel to acquire considerable power.
Born Nov. 1, 1924, in Isparta. Turkish statesman and political figure. Educated as a civil engineer.
Since 1964, Demirel has been the general chairman of the Justice Party. From February to October 1965 he was deputy prime minister, and from October 1965 to March 1971 he was prime minister.
