Lê Duẩn
During the First Indochina War (1946-1954), Lê Duẩn was an active revolutionary leader in South Vietnam. He headed the Central Office of South Vietnam, a Party organ, from 1951 until 1954. During the 1950s Lê Duẩn became increasingly aggressive towards South Vietnam and called for reunification through war. By the mid-to-late 1950s Lê Duẩn had become the second-most powerful policy-maker within the Party, eclipsing former party First Secretary Trường Chinh. By 1960 he was officially the second-most powerful Party member, after Party chairman Hồ. Throughout the 1960s Hồ's health declined and Lê Duẩn assumed more of his responsibilities. On 2 September 1969 Hồ died and Lê Duẩn became the most powerful figure in the North.
