Park Chung Hee, (born Sept. 30 or Nov. 14, 1917, Kumi, North Kyŏngsang province, Korea [now in South Korea]—died Oct. 26, 1979, Seoul, S.Kor.), South Korean general and politician, president of the Republic of Korea (South Korea) from 1963 to his death. His 18-year rule brought about enormous economic expansion, though at the cost of civil liberties and political freedom.
Born into an impoverished rural family, Park graduated (1937) with top honours from Taegu (Daegu) Normal School, after which he taught primary school. After attending a Japanese military academy, Park served as a second lieutenant in the Japanese army during World War II and became an officer in the Korean army when Korea was freed from Japanese rule after the war. He was made a brigadier general (1953) during the Korean War (1950–53) and was promoted to general in 1958. On May 16, 1961, he led a military coup that overthrew the Second Republic. He remained the leader of the junta until two years later, when he won the first of his three terms as president of the Third Republic.
At home Park maintained a policy of guided democracy, with restrictions on personal freedoms, suppression of the press and of opposition parties, and control over the judicial system and the universities. He organized and expanded the Korean Central Intelligence Agency (KCIA; now the National Intelligence Service), which became a much-feared agent of political repression. Park claimed that all his measures were necessary to fight communism. In foreign affairs, he continued the close relations his predecessors Syngman Rhee and Yun Po Sŏn had maintained with the United States. Park was responsible in large part for South Korea’s “economic miracle”; the programs he initiated gave his country one of the fastest-growing economies in the world.
On Oct. 17, 1972, Park declared martial law, and one month later he installed a repressive authoritarian regime, the Yushin (“Revitalization Reform”) order, with a new constitution that gave him sweeping powers. He grew increasingly harsh toward political dissidents. After Park’s dismissal (1979) of popular opposition leader Kim Young Sam from the National Assembly, Korea erupted with severe riots and demonstrations. Park was assassinated by his lifelong friend Kim Jae Kyu, the head of the KCIA.
