On 2 November 1963, Ngô Đình Diệm, the president of South Vietnam, was arrested and assassinated in a CIA-backed coup d'état led by General Dương Văn Minh. After nine years of autocratic and nepotistic family rule in the country, discontent with the Diệm regime had been simmering below the surface and culminated with mass Buddhist protests against longstanding religious discrimination after the government shooting of protesters who defied a ban on the flying of the Buddhist flag.
