Civil war in South Vietnam (AQA GCSE History): Revision Notes
Civil war in South Vietnam
Background to the conflict
Following the Geneva Agreement in 1955, Ngo Dinh Diem emerged as the leader of South Vietnam, marking the beginning of a period that would eventually lead to civil war. The agreement had originally intended for nationwide elections to unify Vietnam, but Diem's refusal to participate in these elections became a crucial factor in triggering internal conflict within South Vietnam.
Diem's refusal to hold the promised nationwide elections was a pivotal moment that violated the Geneva Agreement's intentions and became a primary trigger for the civil war that followed.
Ngo Dinh Diem's rise to power
Early background and political development
Diem came from a Catholic family in a predominantly Buddhist nation, which would later create significant tensions. His family had experienced violent persecution from Buddhists, shaping his worldview and future policies. In 1945, when the Vietminh captured him, Diem demonstrated his strong anti-communist stance by refusing to join Ho Chi Minh's government, choosing self-imposed exile instead.
This early refusal to work with Ho Chi Minh would prove to be a defining characteristic of Diem's political career and would later influence American support for his leadership.
Path to leadership
Diem's journey to power involved several key stages. In 1950, he travelled to the United States, seeking American support for his vision of leading Vietnam. His strong anti-communist beliefs impressed American political leaders, who saw him as a reliable ally in the Cold War context. By 1954, Diem had successfully become the prime minister of South Vietnam, positioning himself to fight against other non-communist rivals who also sought to lead the country.
The 1955 referendum
A crucial moment came in 1955 when a referendum was held in South Vietnam to determine the country's leadership. The choice was between Diem and his rival, Bo Dai, who had been appointed as the leader of South Vietnam by the French. Diem orchestrated the election to ensure his victory, ultimately claiming an implausible 98.2% of the vote to become President of the Republic of Vietnam. This overwhelming "victory" marked the beginning of his authoritarian rule.
The suspicious nature of Diem's electoral "victory" with 98.2% of the vote clearly indicated electoral fraud and foreshadowed the authoritarian methods he would use throughout his rule.
What caused the civil war?
Diem's authoritarian actions
Diem's governance style became the primary catalyst for civil war in South Vietnam. His approach to leadership created widespread opposition through several harmful policies and actions:
He consistently refused to allow fair elections, fearing defeat by Ho Chi Minh and communist forces. This denial of democratic processes alienated many South Vietnamese who had hoped for genuine self-determination.
Diem's security forces systematically arrested individuals who campaigned against his decisions or criticised his government. They also targeted anyone suspected of being a communist sympathiser and those who complained about government corruption. These heavy-handed tactics created a climate of fear and resentment.
Diem's authoritarian tactics included mass arrests of political opponents, suspected communists, and even those who merely criticised government corruption. These actions created widespread fear and resentment among the South Vietnamese population.
Religious and social tensions
Perhaps most damaging was Diem's favouritism towards the Catholic minority in South Vietnam. Despite Catholics representing only a small portion of the population, Diem consistently promoted Catholic interests over those of the Buddhist majority. This religious discrimination created deep resentment among the predominantly Buddhist population and undermined his legitimacy as a national leader.
The religious divide became particularly significant because it wasn't just about faith - it represented a broader pattern of minority rule over the majority, which violated democratic principles and fuelled opposition to Diem's government.
Escalation of opposition
By 1957, opponents of Diem's leadership had begun organising an armed insurgency against his government and supporters. The situation deteriorated further when, in 1959, North Vietnamese leaders made the strategic decision to actively support Diem's opponents, providing them with resources and backing for their resistance efforts.
The civil war: NLF vs ARVN
The National Liberation Front (NLF)
The National Liberation Front represented the main opposition force against Diem's government. Created by North Vietnam's leaders in 1960, the NLF aimed to unite and organise resistance efforts throughout South Vietnam.
Interestingly, many NLF fighters were actually South Vietnamese who had been living in the Vietminh-controlled areas but had relocated to North Vietnam after the Geneva Agreement. When they returned to fight, they brought valuable local knowledge and connections. The NLF received crucial support from North Vietnam through the Ho Chi Minh Trail, a supply network named after the North Vietnamese leader that enabled the movement of resources and personnel.
The Ho Chi Minh Trail became a vital lifeline for the NLF, allowing North Vietnam to provide continuous support to anti-government forces in the South. This supply network would prove crucial throughout the conflict.
The Army of the Republic of Vietnam (ARVN)
On the government side, Diem established the Army of the Republic of Vietnam (ARVN) in 1955 as part of setting up the new South Vietnamese state. The ARVN functioned as a modern military force, receiving substantial support from the United States in the form of funding, equipment, and training.
Diem deployed the ARVN not only against communist NLF forces but also against various non-communist opposition groups, including Buddhist organisations that challenged his authority. This broad use of military force against diverse opposition groups further deepened the country's divisions.
Diem's use of the ARVN against both communist and non-communist opposition groups, including Buddhist organisations, demonstrated how his authoritarian approach alienated potential allies and broadened the resistance against his government.
