Montagnard country of South Indochina

The Montagnard country of South Indochina (French: Pays Montagnard du Sud Indochinois; Vietnamese: Xứ Thượng Nam Đông Dương), sometimes abbreviated as PMSI, was an autonomous territory of French Indochina, and an autonomous federation within the French Union, created in 1946 following the French reconquest of the Central Highlands from the Democratic Republic of Vietnam during the First Indochina War. The territory was supposed to be an autonomous homeland of the Montagnard people within French Indochina, but existed mainly to serve French colonial interests in the region.
