In November 1963, President Ngô Đình Diệm was deposed by a group of CIA-backed Army of the Republic of Vietnam officers who disagreed with Diệm’s handling of the Buddhist crisis and the North Vietnamese and Viet Cong threat to South Vietnam.
The coup, led by General Dương Văn Minh, captured and executed Diem along with his brother and advisor Ngô Đình Nhu.
