Answer
The self-immolation of Thích Quảng Đức, a Vietnamese Mahayana Buddhist monk, on June 11, 1963, in Saigon, was a deliberate act of political protest. Đức's action aimed to raise awareness of the persecution of Buddhists by the South Vietnamese government under President Ngô Đình Diệm and to draw international attention to the cause of religious freedom in Vietnam.
