During World War II in Laos, Vichy France, Thailand, Imperial Japan and Free France occupied Laos. On 9 March 1945, a nationalist group declared Laos once more independent, with Luang Prabang as its capital, but on 7 April 1945 two battalions of Japanese troops occupied the city. The Japanese attempted to force Sisavang Vong (the King of Luang Phrabang) to declare Laotian independence, but on 8 April he instead simply declared an end to Laos's status as a French protectorate. The king then secretly sent Prince Kindavong to represent Laos to the Allied forces and Prince Sisavang as representative to the Japanese. When Japan surrendered, some Lao nationalists (including Prince Phetsarath) declared Laotian independence, but by early-1946, French troops had reoccupied the country and conferred limited autonomy on Laos.
