Acuerdo de Ginebra
Also in 1954, Viet Minh forces took over North Vietnam according to the Geneva Accord. One million North Vietnamese civilians emigrated to South Vietnam to avoid persecution from the imminent Communist regime. At the same time, Viet Minh armed forces from South Vietnam were also moving to North Vietnam, as dictated by the Geneva Accord. However, some high-ranking Viet Minh cadres secretly remained in the South to follow the local situation closely, and created a communist insurgency against the Southern government if necessary. The most important figure among those was Lê Duẩn.
