Hồ Chí Minh (born Nguyễn Sinh Cung; 19 May 1890 – 2 September 1969), colloquially known as Uncle Ho (Bác Hồ) among other aliases and sobriquets, was a Vietnamese revolutionary and politician who served as the founder and first president of the Democratic Republic of Vietnam from 1945 until his death in 1969, and as its first prime minister from 1945 to 1955. Ideologically a Marxist–Leninist, he founded the Indochinese Communist Party in 1930 and its successor Workers' Party of Vietnam (later the Communist Party of Vietnam) in 1951, serving as the party's chairman until his death.

Hồ was born in Nghệ An province in French Indochina, and received a French education. Starting in 1911, he worked in various countries overseas, and in 1920 was a founding member of the French Communist Party in Paris. After studying in Moscow, Hồ founded the Vietnamese Revolutionary Youth League in 1925, which he transformed into the Indochinese Communist Party in 1930. On his return to Vietnam in 1941, he founded and led the Việt Minh independence movement against the Japanese, and in 1945 led the August Revolution against the monarchy and proclaimed the Democratic Republic of Vietnam. After the French returned to power, Hồ's government retreated to the countryside and initiated guerrilla warfare from 1946.

Between 1953 and 1956, Hồ's leadership saw the implementation of a land reform campaign, which included executions and political purges. The Việt Minh defeated the French in 1954 at the Battle of Điện Biên Phủ, ending the First Indochina War. At the 1954 Geneva Conference, Vietnam was divided into two de facto separate states, with the Việt Minh in control of North Vietnam, and anti-communists backed by the United States in control of South Vietnam. Hồ remained president and party leader during the Vietnam War, which began in 1955. He supported the Viet Cong insurgency in the south, overseeing the transport of troops and supplies on the Ho Chi Minh trail until his death in 1969. North Vietnam won in 1975, and the country was re-unified in 1976 as the Socialist Republic of Vietnam. Saigon – Gia Định, South Vietnam's former capital, was renamed Ho Chi Minh City in his honor.

The details of Hồ's life before he came to power in Vietnam are uncertain. He is known to have used between 50 and 200 pseudonyms. 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. Aside from being a politician, Hồ was a writer, poet, and journalist. He wrote several books, articles, and poems in Chinese, Vietnamese, and French.

Hồ Chí Minh was born as Nguyễn Sinh Cung, also known as Nguyễn Sinh Côn, and pronounced locally as Nguyễn Sinh Côông, in 1890 in the village of Hoàng Trù in Kim Liên commune, Nam Đàn district, Nghệ An province, in northern Central Vietnam which was then a French protectorate. Although 1890 is generally accepted as his birth year, at various times he used four other birth years: 1891, 1892, 1894 and 1895. He lived in his father Nguyễn Sinh Sắc's village of Làng Sen in Kim Liên until 1895 when his father sent him to Huế for study. He had three siblings: his sister Bạch Liên (Nguyễn Thị Thanh), a clerk in the French Army; his brother Nguyễn Sinh Khiêm (Nguyễn Tất Đạt), a geomancer and traditional herbalist; and another brother (Nguyễn Sinh Nhuận), who died in infancy. As a young child, Cung (Hồ) studied with his father before more formal classes with a scholar named Vương Thúc Quý. He quickly mastered chữ Hán, a prerequisite for any serious study of Confucianism while honing his colloquial Vietnamese writing. In addition to his studies, he was fond of adventure and loved to fly kites and go fishing. Following Confucian tradition, his father gave him a new name when he turned ten: Nguyễn Tất Thành.

His father, Sắc, was a Confucian scholar and teacher, and later, in 1909, an imperial magistrate in the remote district of Bình Khê in Bình Định province. He was demoted for abuse of power after an influential local figure died several days after having received 102 strokes of the cane as punishment for an infraction. Sắc was both a patriot and a collaborator with the French colonial state, supporting the claimedly 'civilizing mission' of the French. Thành received a French education, attending Collège Quốc học (lycée or secondary education) in Huế in Central Vietnam. His disciples, Phạm Văn Đồng and Võ Nguyên Giáp, also attended the school, as did Ngô Đình Diệm, the future President of South Vietnam and political rival.

His early life is uncertain but there are some documents indicating activities regarding an early revolutionary spirit during French-occupied Vietnam, but conflicting sources remain. Previously, it was believed that Thành (Hồ) was involved in an anti-slavery (anti-corvée) demonstration of poor peasants in Huế in May 1908, which endangered his student status at Collège Quốc học. However, a document from the Centre des archives d'Outre-mer in France shows that he was admitted to Collège Quốc học on 8 August 1908, which was several months after the anti-corvée demonstration (9–13 April 1908).

In Saigon, he applied to work as a kitchen helper on a French merchant steamer, the Amiral de Latouche-Tréville, using the alias Văn Ba. The ship departed on 5 June 1911 and arrived in Marseille, France on 5 July 1911. The ship then left for Le Havre and Dunkirk, returning to Marseille in mid-September. There, he applied for the French Colonial School but did not succeed. He instead decided to begin traveling the world by working on ships and visiting many countries from 1911 to 1917.
