The Vietnam War was a conflict in Vietnam, Laos, and Cambodia from 1 November 1955 to the fall of Saigon on 30 April 1975. It was the second of the Indochina Wars and was a major conflict of the Cold War. While the war was officially fought between North Vietnam and South Vietnam, the north was supported by the Soviet Union, China, and other communist states, while the south was supported by the United States and other anti-communist allies, making the war a proxy war between the United States and the Soviet Union. It lasted almost 20 years, with direct U.S. military involvement ending in 1973. The conflict also spilled over into neighboring states, exacerbating the Laotian Civil War and the Cambodian Civil War, which ended with all three countries officially becoming communist states by 1976.
Ngô Đình Diệm was a South Vietnamese politician who was the final prime minister of the State of Vietnam (1954–1955) and later the first president of South Vietnam from 1955 until his capture and assassination during the CIA-backed 1963 South Vietnamese coup.
South Vietnam, officially the Republic of Vietnam, was a country in Southeast Asia that existed from 1955 to 1975, the period when the southern portion of Vietnam was a member of the Western Bloc during part of the Cold War after the 1954 division of Vietnam. It first received international recognition in 1949 as the State of Vietnam within the French Union, with its capital at Saigon, before becoming a republic in 1955. South Vietnam was bordered by North Vietnam to the north, Laos to the northwest, Cambodia to the southwest, and Thailand across the Gulf of Thailand to the southwest. Its sovereignty was recognized by the United States and 87 other nations, though it failed to gain admission into the United Nations as a result of a Soviet veto in 1957. It was succeeded by the Republic of South Vietnam in 1975. In 1976, the Republic of South Vietnam and North Vietnam merged to form the Socialist Republic of Vietnam.
Hồ Chí Minh, colloquially known as Uncle Ho or just Uncle (Bác), and by other aliases and sobriquets, was a Vietnamese communist revolutionary, nationalist, and politician. He served as prime minister of the Democratic Republic of Vietnam from 1945 to 1955 and as president from 1945 until his death in 1969. Ideologically a Marxist–Leninist, he was the Chairman and First Secretary of the Workers' Party of Vietnam, the predecessor of the current Communist Party of Vietnam.
The Việt Minh (Vietnamese:[vîətmīŋ̟] ; abbreviated from Việt Nam Độc lập Đồng minh, chữ Hán: 越南獨立同盟; French: Ligue pour l'indépendance du Viêt Nam, lit. 'League for the Independence of Vietnam'
The Viet Cong was an epithet and umbrella term to call the communist-driven armed movement and united front organization in South Vietnam, Laos and Cambodia. Formally organized as and led by the National Liberation Front of South Vietnam, it fought under the direction of North Vietnam against the South Vietnamese and United States governments during the Vietnam War. The organization had both guerrilla and regular army units, as well as a network of cadres who organized and mobilized peasants in the territory the Viet Cong controlled. During the war, communist fighters and some anti-war activists claimed that the Viet Cong was an insurgency indigenous to the South that represented the legitimate rights of people in South Vietnam, while the U.S. and South Vietnamese governments portrayed the group as a tool of North Vietnam. It was later conceded by the modern Vietnamese communist leadership that the movement was actually under the North Vietnamese political and military leadership, aiming to unify Vietnam under a single banner.
The Geneva Conference was a conference that was intended to settle outstanding issues resulting from the Korean War and the First Indochina War and involved several nations. It took place in Geneva, Switzerland, from 26 April to 20 July 1954. The part of the conference on the Korean question ended without adopting any declarations or proposals and so is generally considered less relevant. On the other hand, the Geneva Accords that dealt with the dismantling of French Indochina proved to have long-lasting repercussions. The crumbling of the French colonial empire in Southeast Asia led to the formation of the states of the Democratic Republic of Vietnam, the State of Vietnam, the Kingdom of Cambodia, and the Kingdom of Laos. Three agreements about French Indochina, covering Cambodia, Laos, and Vietnam, were signed on 21 July 1954 and took effect two days later.
The State of Vietnam was a governmental entity in Southeast Asia that existed from 1949 until 1955, first as a member of the French Union and later as a country. The state claimed authority over all of Vietnam during the First Indochina War, although large parts of its territory were controlled by the Democratic Republic of Vietnam.
The Personalist Labor Revolutionary Party, often simply called the Cần Lao Party, was a Vietnamese political party, formed in the early 1950s by the President of South Vietnam Ngô Đình Diệm and his brother and adviser Ngô Đình Nhu. Based on mass-organizations and secret networks as effective instruments, the party played a considerable role in creating a political groundwork for Diệm's power and helped him to control all political activities in South Vietnam. The doctrine of the party was ostensibly based on Ngô Đình Nhu's Person Dignity Theory and Emmanuel Mounier's Personalism.
Operation Passage to Freedom was a term used by the United States Navy to describe the propaganda effort and the assistance in transporting in 310,000 Vietnamese civilians, soldiers and non-Vietnamese members of the French Army from communist North Vietnam to non-communist South Vietnam between the years 1954 and 1955. The French and other countries may have transported a further 500,000. In the wake of the French defeat at the Battle of Dien Bien Phu, the Geneva Accords of 1954 decided the fate of French Indochina after eight years of war between the French Union forces and the Viet Minh, which fought for Vietnamese independence under communist rule. The accords resulted in the partition of Vietnam at the 17th parallel north, with Ho Chi Minh's communist Viet Minh in control of the north and the French-backed State of Vietnam in the south. The agreements allowed a 300-day period of grace, ending on May 18, 1955, in which people could move freely between the two Vietnams before the border was sealed. The partition was intended to be temporary, pending elections in 1956 to reunify the country under a national government. Between 600,000 and one million people moved south, including more than 200,000 French citizens and soldiers in the French army while between 14,000 and 45,000 civilians and approximately 100,000 Viet Minh fighters moved in the opposite direction.
CIA activities in Vietnam were operations conducted by the Central Intelligence Agency in Vietnam from the 1950s to the late 1960s, before and during the Vietnam War. After the 1954 Geneva Conference, North Vietnam was controlled by communist forces under Ho Chi Minh's leadership. South Vietnam, with the assistance of the U.S., was anti-communist under Ngo Dinh Diem's leadership. The economic and military aid supplied by the U.S. to South Vietnam continued until the 1974. The CIA participated in both the political and military aspect of the wars in Indochina. The CIA provided suggestions for political platforms, supported candidates, used agency resources to refute electoral fraud charges, manipulated the certification of election results by the South Vietnamese National Assembly, and instituted the Phoenix Program. It worked particularly closely with the ethnic minority Montagnards, Hmong, and Khmer. There are 174 National Intelligence Estimates dealing with Vietnam, issued by the CIA after coordination with the U.S. intelligence community.
North Vietnam, officially the Democratic Republic of Vietnam, was a socialist state in Southeast Asia that existed from 1945 to 1976, with formal sovereignty being fully recognized in 1954. A member of the Eastern Bloc, it opposed the French-supported State of Vietnam and later the Western-allied Republic of Vietnam. North Vietnam emerged victorious over South Vietnam in 1975 and ceased to exist the following year when it unified with the south to become the current Socialist Republic of Vietnam.
The 1954 to 1959 phase of the Vietnam War was the era of the two nations. Coming after the First Indochina War, this period resulted in the military defeat of the French, a 1954 Geneva meeting that partitioned Vietnam into North and South, and the French withdrawal from Vietnam, leaving the Republic of Vietnam regime fighting a communist insurgency with USA aid. During this period, North Vietnam recovered from the wounds of war, rebuilt nationally, and accrued to prepare for the anticipated war. In South Vietnam, Ngô Đình Diệm consolidated power and encouraged anti-communism. This period was marked by U.S. support to South Vietnam before Gulf of Tonkin, as well as communist infrastructure-building.
The 1959 to 1963 phase of the Vietnam War started after the North Vietnamese had made a firm decision to commit to a military intervention in the guerrilla war in the South Vietnam, a buildup phase began, between the 1959 North Vietnamese decision and the Gulf of Tonkin Incident, which led to a major US escalation of its involvement. Vietnamese communists saw this as a second phase of their revolution, the US now substituting for the French.
1959 saw Vietnam still divided into South and North. North Vietnam authorized the Viet Cong (VC) to undertake limited military action as well as political action to subvert the Diệm government. North Vietnam also authorized the construction of what would become known as the Ho Chi Minh Trail to supply the VC in South Vietnam. Armed encounters between the VC and the government of South Vietnam became more frequent and with larger numbers involved. In September, 360 soldiers of the Army of the Republic of Vietnam (ARVN) were ambushed by a force of about 100 VC guerrillas.
In 1955, the Prime Minister of South Vietnam Ngô Đình Diệm faced a severe challenge to his rule over South Vietnam from the Bình Xuyên criminal gang and the Cao Đài and Hòa Hảo religious sects. In the Battle of Saigon in April, Diệm's army eliminated the Bình Xuyên as a rival and soon also reduced the power of the sects. The United States, which had been wavering in its support of Diệm before the battle, strongly supported him afterwards. Diệm declined to enter into talks with North Vietnam concerning an election in 1956 to unify the country. Diệm called a national election in October and easily defeated Head of State Bảo Đại, thus becoming President of South Vietnam.
In 1957 South Vietnam's President Ngô Đình Diệm visited the United States and was acclaimed a "miracle man' who had saved one-half of Vietnam from communism. However, in the latter part of the year, violent incidents committed by anti-Diệm insurgents increased and doubts about the viability of Diệm's government were expressed in the media and by U.S. government officials.
After World War II and the collapse of Vietnam's monarchy, France attempted to re-establish its colonial rule but was ultimately defeated in the First Indo-China War. The Geneva Accords in 1954 partitioned the country temporarily in two with a promise of democratic elections in 1956 to reunite the country. The United States and South Vietnam insisted on United Nations supervision of any election to prevent fraud, which the Soviet Union and North Vietnam refused. North and South Vietnam therefore remained divided until the Vietnam War ended with the Fall of Saigon in 1975.
The following is a list of political organizations and armed forces in Vietnam, since 1912:
When 1954 began, the French had been fighting the insurgent communist-dominated Viet Minh for more than seven years attempting to retain control of their colony Vietnam. Domestic support for the war by the population of France had declined. The United States was concerned and worried that a French military defeat in Vietnam would result in the spread of communism to all the countries of Southeast Asia—the domino theory—and was looking for means of aiding the French without committing American troops to the war.
