Ngô Đình Diệm ( listen; 3 January 1901 – 2 November 1963) was the first president of South Vietnam (1955–1963). In the wake of the French withdrawal from Indochina as a result of the 1954 Geneva Accords, Diệm led the effort to create the Republic of Vietnam. Accruing considerable U.S. support due to his staunch anti-Communism, he achieved victory in a 1955 plebiscite that was widely considered fraudulent. A Roman Catholic, Diệm pursued biased and religiously oppressive policies against the Republic's Montagnard natives and its Buddhist majority, epitomized in Malcolm Browne's Pulitzer Prize winning photograph of the self-immolation of Buddhist monk Thích Quảng Đức in 1963.

Amid religious protests that garnered worldwide attention, Diệm lost the backing of his U.S. patrons and was assassinated, along with his brother, Ngô Đình Nhu by Nguyễn Văn Nhung, the aide of ARVN General Dương Văn Minh on 2 November 1963, during a coup d'état that deposed his government.

Diệm was born in Huế, the original capital of the Vietnamese Nguyễn Dynasty. His family originated in the central Vietnamese village of Phú Cẩm. Portuguese missionaries had converted his family to Roman Catholicism in the 17th century, so Diệm was given a saint's name at birth, following the custom of the Catholic Church. His full name was Jean Baptiste Ngô Đình Diệm. He would often claim that he had descended from a blue-blooded family of mandarins who were so revered that people believed that it was a great honour and good luck to be buried alongside his ancestors. Most historians dismiss this as false and believe that his family were of low rank until his father passed the imperial examinations.^{[citation needed]}

Hồ Chí Minh (Vietnamese pronunciation: [hô cǐ miɲ] (Vietnamese pronunciation: [hô̤ tɕǐmɪŋ] ( listen)); 19 May 1890 – 2 September 1969), born Nguyễn Sinh Cung and also known as Nguyễn Tất Thành and Nguyễn Ái Quốc, was a Vietnamese Stalinist revolutionary leader who was prime minister (1945–1955) and president (1945–1969) of the Democratic Republic of Vietnam (North Vietnam). He was a key figure in the foundation of the Democratic Republic of Vietnam in 1945, as well as the People's Army of Vietnam (PAVN) and the Việt Cộng (NLF or VC) during the Vietnam War.

He led the Việt Minh independence movement from 1941 onward, establishing the communist-governed Democratic Republic of Vietnam in 1945 and defeating the French Union in 1954 at Điện Biên Phủ. He officially stepped down from power in 1955 due to health problems, but remained a highly visible figurehead and inspiration for Vietnamese fighting for his cause – a united, independent Vietnam – until his death. After the war, Saigon, the capital of Republic of Vietnam, was renamed Hồ Chí Minh City in his honor.
