Government Communist state. In the 14th century the first Laotian state was founded, the Lan Xang kingdom, which ruled Laos until it split into three separate kingdoms in 1713. Its territory was incorporated into the union of Indochina. A strong nationalist movement developed during World War II, but France reestablished control in 1946 and made the king of Luang Prabang constitutional monarch of all Laos. France granted semiautonomy in 1949 and then, spurred by the Viet Minh rebellion in Vietnam, full independence within the French Union in 1950.
