The longest-serving General Secretary who reunified Vietnam and invaded Cambodia in his 26-year rule
“Our party is the unique and single leader that organised… the entire struggle of the Vietnamese people from the first day of the revolution.” — reunification victory speech, 1976
A Vietnamese communist politician and theorist. A founding member of the Indochina Communist Party in 1930, he endured two French prison terms before earning Ho Chi Minh's trust and taking charge of the southern revolutionary apparatus. In 1956 he authored The Road to the South, providing the theoretical basis for the armed liberation struggle against the Saigon regime, and at the 3rd National Congress in 1960 he was elected First Secretary, becoming the party's supreme leader after Ho's death in 1969. He completed Vietnam's reunification in 1975, ordered the invasion of Cambodia to overthrow the Khmer Rouge in 1978, and held power through the Sino-Vietnamese War (1979) until his death in 1986.

Rebuilding the Southern Apparatus and the Turn to Armed Struggle, 1954-1959
After the 1954 Geneva Accords temporarily divided Vietnam, Lê Duẩn was sent back south to publicize the agreement's terms and to prepare the regroupment and the nationwide elections scheduled for 1956. Ordered to regroup to the North, he cabled three times asking to stay; only the third request was approved.
He rebuilt the southern apparatus. When the Central Office of South Vietnam was dissolved in late 1954 and the Nam Bộ regional committee restored, he became its secretary, dividing the region into three inter-provincial zones (eastern, central and western Nam Bộ) plus a special Saigon-Cholon zone. In 1955 he established a secret base in Saigon and in August 1957 drafted the Southern Revolutionary Theses, which proposed combining political and armed struggle should the Geneva Accords not be fully implemented. Outwardly loyal to the Central Committee's peaceful political line, the text emphasized building forces to overthrow the U.S.-backed Diệm government, drawing a distinction between reformist legal work and revolutionary mass-based political struggle.
Recalled to Hanoi in April 1957, he outmaneuvered Trường Chinh, still the country's second-ranking figure, and expanded his network; in November 1957 he visited Moscow and received approval for his war plans. In December Hồ Chí Minh explained a "dual revolution" to the 13th Plenum, assigning Trường Chinh the socialist transformation of the North and Lê Duẩn the planning of the offensive in the South.
At the enlarged 15th Central Committee Plenum in January 1959, Lê Duẩn presented the final draft resolution combining political and armed struggle against Ngô Đình Diệm's government, arguing that Diệm had violated the Geneva Accords by refusing unification elections. To accommodate more cautious opinion within the party, the document retained a defensive posture, holding that armed struggle would be undertaken for self-defence and counterattack only when met with violent repression. Immediately after the plenum he made a secret inspection trip to the South and recorded mounting repression under Diệm, including Law 10/59, which permitted capital punishment for suspected opponents. In May 1959 the Central Committee approved implementation of Resolution 15 and established Group 559, the unit that organized the strategic military transport route along the Trường Sơn range, later known as the Ho Chi Minh Trail.
Two source-critical points stand out. First, the 1957 theses show him operating simultaneously on the plane of treaty implementation and the plane of preparing armed capacity; his formal adherence to the Central Committee's line coexisted with advocacy of insurgent organization. Second, the adoption of Resolution 15 is described as the product of several converging factors, Diệm's repression, pressure from southern cadres facing that repression, and the initiative of Lê Duẩn together with southern-oriented leaders such as Lê Đức Thọ and Phạm Hùng, rather than any single cause.
