Buddhist monk Thích Quảng Đức burns himself with gasoline in a busy Saigon intersection to protest the lack of religious freedom in South Vietnam.

Thích Quảng Đức (Vietnamese: [tʰǐk̟ kʷâːŋ ɗɨ̌k] (listen); 1897 – 11 June 1963; born Lâm Văn Túc) was a Vietnamese Mahayana Buddhist monk who burned himself to death at a busy Saigon road intersection on 11 June 1963. Quảng Đức was protesting the persecution of Buddhists by the South Vietnamese government led by Ngô Đình Diệm, a staunch Roman Catholic. Photographs of his self-immolation circulated around the world, drawing attention to the policies of the Diệm government. John F. Kennedy said of one photograph, "No news picture in history has generated so much emotion around the world as that one." Malcolm Browne won a Pulitzer Prize for his photograph of the monk's death.Quảng Đức's act increased international pressure on Diệm and led him to announce reforms with the intention of mollifying the Buddhists. However, the promised reforms were not implemented, leading to a deterioration in the dispute. As protests continued, the ARVN Special Forces loyal to Diệm's brother, Ngô Đình Nhu, launched raids across South Vietnam on Buddhist pagodas, seizing Quảng Đức's heart and causing deaths and widespread damage. Several Buddhist monks followed Quảng Đức's example, also immolating themselves. Eventually, a U.S.-backed coup toppled Diệm, who was assassinated on 2 November 1963.
