Hồ Chí Minh[a] (born Nguyễn Sinh Cung;[b][3][4] 19 May 1890 – 2 September 1969[c]), commonly known as Bác Hồ ('Uncle Hồ')[7] or simply known as Bác,[d] also known as Hồ Chủ tịch ('President Hồ'), Nguyễn Tất Thành, Nguyễn Ái Quốc, Người cha già của dân tộc ('Father of the people'), was a Vietnamese revolutionary and statesman. He served as Prime Minister of North Vietnam from 1945 to 1955 and he also served as President of North Vietnam from 1945 until his death in 1969. Ideologically a Marxist–Leninist, he served as Chairman and First Secretary of the Workers' Party of Vietnam. Hồ Chí Minh was born in Nghệ An province, in Central Vietnam. He led the Việt Minh independence movement from 1941 onward. Initially, it was an umbrella group for all parties fighting for Vietnam's independence, but the Communist Party gained majority support after 1945. Hồ Chí Minh led the Communist-led Democratic Republic of Vietnam in 1945, defeating the French Union in 1954 at the Battle of Điện Biên Phủ, ending the First Indochina War, and resulting in the division of Vietnam, with the Communists in control of North Vietnam. He was a key figure in the People's Army of Vietnam and the Việt Cộng during the Vietnam War, which lasted from 1955 to 1975. Ho officially stepped down from power in 1965 due to health problems and died in 1969. North Vietnam was ultimately victorious against South Vietnam and its allies, and Vietnam was officially unified in 1976. Saigon, the former capital of South Vietnam, was renamed Ho Chi Minh City in his honor. The details of Hồ Chí Minh's life before he came to power in Vietnam are uncertain. He is known to have used between 50[8]: 582 and 200 pseudonyms.[9] Information on his birth and early life is ambiguous and subject to academic debate. At least four existing official biographies vary on names, dates, places, and other hard facts while unofficial biographies vary even more widely.[10] Aside from being a politician, Ho was also a writer, a poet, and a journalist. He wrote several books, articles and poems in Chinese, Vietnamese and French.
