Việt Minh in the context of Mường Thanh Valley

The First Indochina War (generally known as the Indochina War in France, and as the Anti-French Resistance War in Vietnam, and alternatively internationally as the French Indochina War) was fought in Indochina between France and the Việt Minh, and their respective allies, from 19 December 1946 until 1 August 1954. The Việt Minh was led by Võ Nguyên Giáp and Hồ Chí Minh. The conflict mainly happened in Vietnam.

At the Potsdam Conference in July 1945, the Allied Combined Chiefs of Staff decided that Indochina south of latitude 16° north was to be included in the Southeast Asia Command under British Admiral Mountbatten. The French return to southern Indochina was also supported by the Allies. On V-J Day, September 2, Hồ Chí Minh proclaimed in Hanoi the establishment of the Democratic Republic of Vietnam (DRV). Also in September 1945, Chinese forces entered Hanoi, and Japanese forces to the north of that line surrendered to Generalissimo Chiang Kai-shek. At the same time, British forces landed in Saigon, and Japanese forces in the south surrendered to the British. The Chinese acknowledged the DRV and the communist-led Việt Minh, then in power in Hanoi, even though they also supported pro-Chinese nationalist factions. The British refused to do that in Saigon, and deferred to the French. The DRV ruled as the only civil government in all of Vietnam for a period of about 20 days, after the abdication of Emperor Bảo Đại, who had governed Vietnam since 1926.

The People's Army of Vietnam (PAVN), officially the Vietnam People's Army (VPA; Vietnamese: Quân đội nhân dân Việt Nam, pronounced [kwən˧˧ ʔɗoj˧˨ʔ ɲən˧˧ zən˧˧ viət̚˧˨ʔ naːm˧˧], lit. 'Military of and for the people of Vietnam'), also recognized as the Vietnamese Army (Vietnamese: Quân đội Việt Nam, lit. 'Military of Vietnam'), the People's Army (Vietnamese: Quân đội Nhân dân) or colloquially the Troops (Bộ đội [ʔɓo˧˨ʔ ʔɗoj˧˨ʔ]), is the national military force of the Socialist Republic of Vietnam and the armed wing of the ruling Communist Party of Vietnam (CPV). The PAVN is the backbone component of the Vietnam People's Armed Forces and includes: Ground Force, Navy, Air Force, Border Guard and Coast Guard. Vietnam does not have a separate and formally-structured Ground Force or Army service. Instead, all ground troops, army corps, military districts and special forces are designated under the umbrella term combined arms (Vietnamese: binh chủng hợp thành) and belong to the Ministry of National Defence, directly under the command of the CPV Central Military Commission, the Minister of National Defence, and the General Staff of the Vietnam People's Army.

During the French Indochina War (1946–1954), the PAVN was often referred to as the Việt Minh. In the context of the Vietnam War (1955–1975), the army was referred to by its opposition forces as the North Vietnamese Army (NVA; Vietnamese: Quân đội Bắc Việt), serving as the military force of the Democratic Republic of Vietnam. This allowed writers, the U.S. military, and the general public, to distinguish northern communists from the southern communists, called the Viet Cong (VC), or more formally the National Liberation Front. However, both groups ultimately worked under the same command structure. The Viet Cong had its own military forces called the Liberation Army of South Vietnam (LASV). It was practically considered a branch of the PAVN by the North Vietnamese. In 1976, following the political reunification of Vietnam, LASV was officially disbanded and merged into the so-called NVA to form the existing incarnation of PAVN, serving as the national military of the unified state of the Socialist 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.

Việt Bắc (Northern Vietnam) is a region of Vietnam north of Hanoi that served as the Việt Minh's base of support during the First Indochina War (1946–1954).

Việt Bắc is also called the capital of northernmost Vietnam because this area was the location of the headquarters of the Communist Party of Vietnam at the period before the rising against French domination in 1945, and the location of the headquarters of the Việt Minh government during the war of resistance against the French colonialists.
