Explanation:
French Indochina was a federation of protectorates in Southeast Asia that was part of the French colonial empire. France assumed sovereignty over Annam and Tonkin after the Franco-Chinese War, which lasted from 1884 to 1885. French Indochina was formed in October 1887 by Annam, Tonkin, Cochinchina and the Kingdom of Cambodia. Laos was added in 1893. The federation lasted until 1954 and the capital was Saigon. The French left the local rulers in power, who were the emperors of Vietnam, the kings of Cambodia and the kings of Luang Prabang, but in practice they acted only as figureheads.
