The Vietnamese
Indochina
When the French arrived, they helped build the Vietnamese empire which was headed by a prince. The empire successfully built, To return the favour, the French missionaries were allowed to spread Christianity in Indochina. They were also regarded as the advisers of the local dynasty.
He did not want the Vietnamese to take over the french colony of Indochina
After the BATTLE OF DIEN BIEN PHU, the French considered the First Indochina War to have been a defeat and withdrew from all Indochina (including Vietnam).
France ruled it, and this is why it was called "French" Indochina.
There was no such person. Vietnam was then French Indochina, a colony of France, and after the summer of 1941 it was occupied by the Japanese.
European Imperialism qualifies as such.
France was the only country after WW2 that refused to grant independence to its Asian colonies. Ho Chi Minh had tried to ask the U.S. to help negotiate with the French, but the U.S. refused because he had had communist contacts during WW2. That left no option but a war of independence against France, which as the only military support he could get was from his previous communist contacts Vietnam eventually became a communist nation.
The First Indochina War (also known as the French Indochina War, Anti-French War, Franco-Vietnamese War, Franco-Vietminh War, Indochina War, Dirty War in France, and Anti-French Resistance War in contemporary Vietnam) was fought in French Indochina from December 19, 1946, until August 1, 1954, between the French Union's French Far East Expeditionary Corps, led by France and supported by Emperor Bảo Đại's Vietnamese National Army against the Việt Minh, led by Hồ Chí Minh and Võ Nguyên Giáp. Most of the fighting took place in Tonkin in Northern Vietnam, although the conflict engulfed the entire country and also extended into the neighboring French Indochina protectorates of Laos and Cambodia.
If someone were to class "communism" as a form of "imperialism" then yes that was one of the causes of the Vietnam War. The French Indochina War (1st Indochina War) was "basically" a war of imperialism; and had NOT the Viet Minh been backed by the communists, the US would have probably stayed clear of that conflict. But since the now (then) North Vietnamese were COMMUNISTS, and clearly supported by the Communist Superpowers, and we, the US, were a "pledged enemy" of communism; WE had to stop the attempted conquest of SOUTH Vietnam. It was only the geography of the land, and the fear of starting World War III (the involvement of the Communist Superpowers-as had happened in the Korean War when Red China entered into it) that prevented us from saving the South.
The French had fought there from 1946 to 1954; 1st Indochina War or French Indochina War.
