Nguyen Van Thieu

Nguyen Van Thieu was elected president of South Vietnam in a US-supervised election, with Nguyen Cao Ky as vice president. The election was marred by fraud and limited participation, but it provided a veneer of legitimacy for the military-dominated government during the Vietnam War.

North Vietnamese and Viet Cong forces launched the Tet Offensive, a massive surprise attack on cities and military bases across South Vietnam. Thieu's government survived the assault, but the offensive exposed the vulnerability of the regime and shifted US public opinion against the war.

Thieu reluctantly signed the Paris Peace Accords, which called for a ceasefire and US withdrawal from Vietnam. The agreement allowed North Vietnamese troops to remain in the South, and Thieu's government was left to fight alone, leading to its eventual collapse.

As North Vietnamese forces advanced on Saigon, Nguyen Van Thieu resigned the presidency and fled to Taiwan. His departure marked the end of South Vietnam, which surrendered unconditionally days later, leading to the reunification of Vietnam under communist rule.
