info on Vietnam History before French withdrawal in 1954

Vietnam's independence ended in the mid-1800s, when the country was colonized by the French. The French administration imposed significant political and cultural changes on Vietnamese society. A Western-style system of modern education was developed, and Christianity was introduced into Vietnamese society. Developing a plantation economy to promote the exports of tobacco, indigo, tea and coffee, the French largely ignored increasing calls for self-government and civil rights. A nationalist political movement soon emerged, with leaders such as Phan Boi Chau, Phan Chu Trinh, Emperor Ham Nghi and Ho Chi Minh calling for independence. However, the French maintained control of their colonies until World War II, when the Japanese war in the Pacific triggered the invasion of French Indochina in 1941. This event was preceded by the establishment of the Vichy French administration, a puppet state of Nazi Germany then ally of the Japanese Empire. The natural resources of Vietnam were exploited for the purposes of the Japanese Empire's military campaigns into the British Indochinese colonies of Burma, the Malay Peninsula and India
