Democratic Republic of Vietnam in the context of "First Indochina War"

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 Marxist-Leninist 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.

Central Vietnam (Vietnamese: Trung Bộ or miền Trung), also known as Middle Vietnam or The Middle, formerly known as Trung Việt by the State of Vietnam, Trung Phần by the Republic of Vietnam, Trung Kỳ or Annam under French colonial rule, is one of the three geographical regions within Vietnam.

The name Trung Bộ was used by the emperor Bảo Đại when he established administrative level higher than Province in 1945, instead of the Trung Kỳ which recalled the French occupation. This name was officially used by government of the Democratic Republic of Vietnam and is popularly used today.

Southern Vietnam (Vietnamese: Nam Bộ) is one of the three geographical regions of Vietnam, the other two being Northern and Central Vietnam. It includes 2 administrative subregions, which in turn are divided into 19 First Tier units, of which 17 are provinces and 2 are municipalities.

Known as Nam Bộ today in Vietnamese, it was historically called Gia Định (1779–1832), Nam Kỳ (1832–1945, during Nguyễn's Lục tỉnh and French Cochinchina), Nam Bộ (1945 to the present, encompassing the Empire of Vietnam and the Democratic Republic of Vietnam), and Nam Phần, sometimes Nam Việt (1948–1975, during the State of Vietnam and the Republic of Vietnam). Cochinchina is a historical exonym for this region during the colonial period, which referred to the entire domain of Đàng Trong in the feudal period. A more accurate term for the southern region is Lower Cochinchina, or Basse-Cochinchine in French.

The Military of the Nguyễn dynasty (Vietnamese: Quân thứ; chữ Hán: 軍次) were the main military forces of the Nguyễn dynasty from 1802 to August 1945 when it was dismantled by the August Revolution. The Nguyễn military force was initially formed by Nguyễn Hoàng as a division of the military of the Revival Lê dynasty in 1558 starting out with 3000 soldiers. During this period it was the military forces of the domain of the Nguyễn lords and commonly fought the Trịnh lords who controlled northern Vietnam. During the Tây Sơn Rebellion it was expelled out most of the county by the Tây Sơn dynasty. After the exiled Nguyễn Phúc Ánh returned and defeated the Tây Sơn rebels he crowned himself as the Gia Long Emperor and the Nguyễn military became the national military of Vietnam.

During the French domination period it became two of the five indigenous guards of French Indochina and was turned into a collection police and ceremonial forces. While the Emperor was still nominally the supreme commander actual power fell in the hands of the French administration relegating the Emperor to a rubber stamp office. Following the abolition of the Nguyễn dynasty its military was also disbanded making the Vietnamese People's Army the new national military of Vietnam, which would be administered by the newly established Democratic Republic of Vietnam.

Võ Nguyên Giáp (chữ Hán: 武元甲, Vietnamese pronunciation: [vɔ̌ˀ ŋʷīən jǎːp]; 25 August 1911 – 4 October 2013) was a Vietnamese general, communist revolutionary and politician. Highly regarded as a military strategist, Giáp led Vietnamese communist military forces to victory in the decades long Indochina wars. Giáp was the military commander of the Việt Minh and the People's Army from 1941 to 1972, minister of defense of the Democratic Republic of Vietnam (North Vietnam) and the Socialist Republic of Vietnam in 1946–1947 and from 1948 to 1980, and deputy prime minister from 1955 to 1991. He was a member of the Politburo of the Communist Party of Vietnam.

Born in Quảng Bình province to an affluent peasant family, Giáp began participating in anti-colonial political activity in 1925. Sources conflict as to whether he joined the Indochinese Communist Party in 1930, or not until 1940. Giáp rose to prominence during World War II as the military leader of the Việt Minh resistance against the Japanese occupation, and after the war led anti-colonial forces in the First Indochina War against the French. He won a decisive victory at the 1954 Battle of Dien Bien Phu, which ended the war. In the Vietnam War, Giáp led the PAVN against South Vietnam and the United States. Giáp was commander of the army during the 1968 Tet Offensive and 1972 Easter Offensive, after which he was succeeded by Văn Tiến Dũng, but remained defense minister through the U.S. withdrawal and final victory against South Vietnam in 1975. Giáp oversaw his final campaigns in the successful Vietnamese invasion of Cambodia in 1978 and the 1979 Sino-Vietnamese War. He resigned as defense minister in 1980 and left the Politburo in 1982. Giáp remained on the Central Committee and as deputy prime minister until 1991, and died in 2013 at age 102.

Lai Châu is a mountainous province in the Northwest region of Vietnam. Lai Châu province is one of the most sparsely populated regions in Vietnam, and it shares a border with China. It was once a semi-independent White Tai confederation known as Sip Song Chau Tai, but was absorbed by France into French Indochina in the 1880s and subsequently became part of Vietnam following Vietnamese independence in 1954. It became part of the Northwest Autonomous Area of the Democratic Republic of Vietnam from 1955 to 1975, when Lai Châu province was formed. Điện Biên province was carved out of Lai Châu in 2004. The province covers an area of about 9,069 km (3,501 sq mi) and as of 2022 it had a population of 482,100 people.

Trường Chinh (Vietnamese: [ʈ͡ʂɯɤ̀ŋ ciŋ̟], meaning "Long March"), born Đặng Xuân Khu (9 February 1907 – 30 September 1988) was a Vietnamese communist political leader, revolutionary and theoretician. He was one of the key figures of Vietnamese politics for over 40 years, and played a major role in the 1946-54 war against the French. Trường also played an important role in shaping the politics of the Democratic Republic of Vietnam (DRV) and creating the socialist structure of the new Vietnam.

Between November 9, 1940 and November 11, 1945, when the party dissolved, Trường was General Secretary of the Indochinese Communist Party Central Committee. Between 1946 and 1954, the First Indochina War led to the fall of French Indochina and the partitioning of Vietnam between north and south. On February 19, 1951, Trường became First Secretary of the Workers' Party of Vietnam Central Committee (although Hồ Chí Minh, in his capacity as founder and chairman of the party, was Trường's superior). In 1956, after the failure of the Land Reform program, he was dismissed from his post of General Secretary and had less power. Hồ Chí Minh selected Lê Duẩn to succeed him as the General Secretary and Lê became the most powerful person in the party after Hồ Chí Minh's death in 1969. However, Trường Chinh remained an influential force in the party during the Second Indochina War and after the reunification of Vietnam; he was Chairman of the National Assembly of Vietnam from 1960 to 1981 and head of state of Vietnam from 1981 to 1987 as 3rd President of Vietnam. Following the death of Lê Duẩn in July 1986, Trường again became General Secretary, and held the post until December 18, 1986. His last vital role was to carry forward the Đổi Mới renovation that still affects Vietnam to this day.
