How did the countries of french indochina gain their independence? france granted independence to avoid supporting the colonies any longer. a military junta systematically overthrew the french regime in each country. communist forces waged a successful war for independence. the united states negotiated with france on behalf of the colonies.

The correct answer is: "Communist forces waged a successful war for independence"

French Indochina is the region which comprised several French colonies in Asia's Southeast. It was mainly constituted by the current territory of Vietnam.  

The region was under the Vichy regime during the nazi occupation of France in WWII. When the war ended, a communist organization named Viet Minh, declared the independence of Vietnam. This triggered the start of the First Indochina War in 1946, fought between the French forces and Viet Minh.

At the end of the conflict, the North of the country (above 17th parallel) was put under the control of the Viet Minh, while the South pertained to the Republic of Vietnam. In any case, the French forces were not in control anymore.
