Royaume du Laos
Sympathetic to the French in Laos, he commanded a force of 15,000 that fought Japanese troops and the Lao Issara in the south of Laos. Titular leader of the royalist faction (and one of the Three Princes of the Kingdom of Laos), he served as Prime Minister of the Kingdom of Laos from March 1949 to February 1950 and again from December 1960 to June 1962 when The National Assembly installed him by unanimous vote.
