After the end of French colonial rule in 1954, two independent governments emerged in Vietnam, the Republic of Vietnam (RVN) in the South, and the Democratic Republic of Vietnam (DRV) in the North. After the North won the Vietnam War and took control of all of Vietnam, the DRV became the Socialist Republic of Vietnam (SRV). The current constitution was promulgated in 1980 and was patterned after the Soviet model, which combined nominal democratic ideas, such as the concept of elections by secret ballot, with the Leninist concept of a dominant Communist party ruling by dictatorial means in the overall interests of the people. In 1992 the constitution was amended to reflect economic reforms undertaken in 1986 as well as a decision to reduce the role of the party in the governing process.
