Hồ Chí Minh in the context of "Declaration of independence of the Democratic Republic of Vietnam"

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 five pillars (Vietnamese: bộ ngũ, pronounced [tɨ˧˦ t͡ɕu˧˨ʔ]; or ngũ trụ), previously the four pillars (tứ trụ), is an informal term for the five most important party-state leaders in the Communist Party of Vietnam and the Government of Vietnam. In modern usage, the five pillars refer to the General Secretary of the Communist Party of Vietnam, President of Vietnam, Prime Minister of Vietnam, Chairman of the National Assembly of Vietnam, and the Permanent Member of the Secretariat. Together, they are officially designated as the "Key Leaders of the Party and the State" (Vietnamese: Lãnh đạo chủ chốt của Đảng và Nhà nước) and can be considered as the de facto highest state leaders. Similar to China, there does not exist an official order of precedence for political leaders and rather they are inferred in a de facto fashion. However, since the chairmanship of the Communist Party was abolished, the General Secretary has been the highest ranking official in Vietnam. This division of power is formed to prevent dictatorial rule and preserve consensus-based leadership, which is officially called by the Vietnamese Communist Party as "democratic centralism". In 2025, the seat of Permanent Member of the Secretariat of CPV was designated as the fifth "key leader", virtually becoming the fifth pillar of the Vietnamese politics.

Unlike other communist states, the General Secretary of the party (or its predecessor) and the President of the state are largely occupied not by the same person, demonstrating the collective leadership in Vietnam. The only exceptions are: Hồ Chí Minh (1951–69), Trường Chinh (briefly in 1986), Nguyễn Phú Trọng (2018–21), and Tô Lâm (briefly in 2024), and except Hồ Chí Minh, all of those exceptions were practically elected to fulfill their successors' uncompleted terms of party general secretaryship or state presidency. Thus, the Party General Secretaries rarely hold offices that are nominally within the Vietnamese state apparatus and government except their parliament memberships, however is still managed to be the practical highest leader in the politics of Vietnam and is ideologically the highest commander of the People's Army of Vietnam, due to the ex officio occupation of the Secretaryship of the Party Central Military Commission.
