France began its conquest of Indochina in the late 1850s, and completed pacification by 1893. The 1884 Treaty of Huế formed the basis for French colonial rule in Vietnam for the next seven decades. In spite of military resistance, most notably by the Cần Vương of Phan Đình Phùng, by 1888 the area of the current-day nations of Cambodia and Vietnam was made into the colony of French Indochina (Laos was later added to the colony).[64] Various Vietnamese opposition movements to French rule existed during this period, such as the Việt Nam Dân Đảng who staged the failed Yên Bái mutiny in 1930, but none were ultimately as successful as the Viet Minh common front, which was founded in 1941, controlled by the Indochinese Communist Party, and funded by the U.S. and the Chinese Nationalist Party in its fight against Japanese occupation.
