Why does the first Indochina war start?

The First Indochina War began in 1946 primarily due to the desire of the Viet Minh, led by Ho Chi Minh, to gain independence from French colonial rule after World War II. Following Japan's occupation of Vietnam during the war, the French attempted to reassert control over their former colony, igniting nationalist sentiments among the Vietnamese population. The conflict escalated as the Viet Minh launched a guerrilla campaign against French forces, ultimately leading to a protracted war that lasted until 1954. The war ended with the Geneva Accords, which temporarily divided Vietnam and set the stage for future conflicts.
