Dương Văn Minh, popularly known as Big Minh, was a South Vietnamese politician and a senior general in the Army of the Republic of Vietnam (ARVN) and a politician during the presidency of Ngô Đình Diệm. In 1963, he became chief of a military junta after leading a coup in which Diệm was assassinated. Minh lasted only three months before being toppled by Nguyễn Khánh, but assumed power again as the fourth and last President of South Vietnam in April 1975, two days before surrendering to North Vietnamese forces. He earned his nickname "Big Minh", because he was approximately 1.83 m (6 ft) tall and weighed 90 kg (198 lb).

South Vietnam, officially the Republic of Vietnam, was a country in Southeast Asia that existed from 1955 to 1975, the period when the southern portion of Vietnam was a member of the Western Bloc during part of the Cold War after the 1954 division of Vietnam. It first received international recognition in 1949 as the State of Vietnam within the French Union, with its capital at Saigon, before becoming a republic in 1955. South Vietnam was bordered by North Vietnam to the north, Laos to the northwest, Cambodia to the southwest, and Thailand across the Gulf of Thailand to the southwest. Its sovereignty was recognized by the United States and 87 other nations, though it failed to gain admission into the United Nations as a result of a Soviet veto in 1957. It was succeeded by the Republic of South Vietnam in 1975. In 1976, the Republic of South Vietnam and North Vietnam merged to form the Socialist Republic of Vietnam.
