Vietnam during World War II between 1939 and 1945 Vietnamese guerrillas (Viet Minh) fought against the French and Japanese. Before World War II the French ruled Vietnam, then the Japanese took over, when this happened the communist leader Ho Chi Minh, who established the Vietminh in 1945, fought the Japanese and defeated them. When the Japanese were defeated, the French attempted to rule Vietnam again, Ho Chi Minh also fought them, however the Americans supported the French because they did not want Vietnam to become communist under Ho Chi Minh. However Ho Chi Minhalso defeated the French. The VietMinh was founded in Vietnam by Ho ChiMinh in 1941. The Vietminh drew inspiration mainly from Ho ChiMinh who was known as a patriot and Marxist-Leninist and was a devout communist.
