prime minister of Greece from 1990 to 1993.

Mitsotakis came from a political family; his father and grandfathers were members of parliament, and the statesman Eleuthérios Venizélos was his uncle. Mitsotakis studied law and economics in Athens. Active in the resistance during the Nazi occupation of Crete (1941–44), he was twice arrested and sentenced to death.

Mitsotakis was first elected to parliament in 1946 as a member of the Liberal Party. In the early 1960s he joined the new Centre Union, a centre-left coalition organized by Georgios Papandreou (Papandreou, Georgios), and he became minister of finance in Papandreou's government. In July 1965 Papandreou became involved in a power struggle with Greece's King Constantine II. Mitsotakis, with other Centre Union deputies, defected from the party and joined the pro-monarchist forces in a series of coalition governments. His actions incurred the lasting animosity of Papandreou's son, Andreas (later to become prime minister himself), and the government crises that followed led in April 1967 to the imposition of a military dictatorship. This government arrested Mitsotakis, who eventually fled to Paris, where he was active in the opposition to the regime.

Mitsotakis returned to Greece in 1973. In 1974, after the fall of the military government, he stood for parliament as an independent liberal but failed to be elected. He founded the centrist New Liberal Party in 1977, and in that same year he was elected to parliament. In the following year Mitsotakis accepted a cabinet post in the government of Konstantinos Karamanlis (Karamanlis, Konstantinos), and shortly afterward he joined Karamanlis' centre-right New Democracy Party. In 1984 Mitsotakis became party leader, and in 1990 he became prime minister. His government's economic-reform policies attracted opposition, however, as did its foreign policy, and in 1993 New Democracy lost its majority in parliament. Mitsotakis stepped down as prime minister and resigned as leader of the party.
