noun

1. Official name: Socialist Republic of Vietnam.  a republic in SE Asia: an ancient empire, conquered by France in the 19th century; occupied by Japan (1940–45) when the Communist-led Vietminh began resistance operations that were continued against restored French rule after 1945. In 1954 the country was divided along the 17th parallel, establishing North Vietnam (under the Vietminh) and South Vietnam (under French control), the latter becoming the independent Republic of Vietnam in 1955. From 1959 the country was dominated by war between the Communist Vietcong, supported by North Vietnam, and the South Vietnamese government; increasing numbers of US forces were brought to the aid of the South Vietnamese army until a peace agreement (1973) led to the withdrawal of US troops; further fighting led to the eventual defeat of the South Vietnamese government in March 1975 and in 1976 an elected National Assembly proclaimed the reunification of the country. Official language: Vietnamese. Religion: Buddhist majority. Currency: dong. Capital: Hanoi. Pop: 92 477 857 (2013 est). Area: 331 041 sq km (127 816 sq miles)

Vietnam was under the control of France from the second half of the nineteenth century until World War II, when it was occupied by the Japanese. The country became an autonomous state in 1946. France's attempts to reassert control resulted in the French Indochina War (1946–1954), in which the French were defeated.

Great numbers of Vietnamese refugees, known as boat people, fled the country in the aftermath of the war.
