French Indochina (French: Indochine française; Vietnamese: Đông Dương thuộc Pháp, frequently abbreviated to Đông Pháp) was part of the French colonial empire in southeast Asia. A federation of the three Vietnamese regions, Tonkin (North), Annam (Central), and Cochinchina (South), as well as Cambodia, was formed in 1887. Laos was added in 1893 and Guangzhouwan (Kouang-Tchéou-Wan) in 1900. The capital was moved from Saigon (in Cochinchina) to Hanoi (Tonkin) in 1902.
