The Vietnam War
Nguyen Van Thieu (1923 - 2001) was a military general who served in the French-controlled Vietnamese army during French colonial rule in Indochina, and later served as president of South Vietnam during the war against the North.
During the Vietnam War, Thieu maintained a powerful role in the South Vietnamese government under President Nguyen Cao Ky. In 1967, he replaced Ky and remained president of South Vietnam until the final days of the war against the North. Just before the fall of Saigon, Thieu fled to Taiwan.
