title: Arrest and assassination of Ngo Dinh Diem
context: The arrest and assassination of Ngô Đình Diệm, the president of South Vietnam, marked the culmination of a successful CIA-backed coup d'état led by General Dương Văn Minh in November 1963. On 2 November 1963, Diệm and his adviser, his younger brother Ngô Đình Nhu, were arrested after the Army of the Republic of Vietnam (ARVN) had been successful in a bloody overnight siege on Gia Long Palace in Saigon. The coup was the culmination of nine years of autocratic and nepotistic family rule in South Vietnam. Discontent with the Diệm regime had been simmering below the surface, and exploded with mass Buddhist protests against long-standing religious discrimination after the government shooting of protesters who defied a ban on the flying of the Buddhist flag.
