Buddhist crisis
The crisis was started when the President Ngô Đình Diệm banned the flying of the Buddhist flag. That led to the shooting of nine unarmed civilians who were protesting a ban of the Buddhist flag on May 8 and suicide by burning of Thích Quảng Đức on June 11. The crisis ended when Ngô Đình Diệm was assassinated on November 2, 1963.
