Throughout more than 70 years of its history, the Vietnam National Assembly has passed five constitutions: the 1946 Constitution, the 1959 Constitution, the 1980 Constitution, the 1992 Constitution and the 2013 Constitution. Each Constitution has marked the road of growth of the Vietnamese revolutionary state, serving as the foundation for completing the legal system and building a law-ruled socialist state of Vietnam of the people, by the people and for the people.
