Causes of the Vietnam War

- The Vietnam War emerged from the division of Vietnam after the Geneva Accords, conflicting visions for national unification, and Cold War strategic competition.
- The Geneva Accords of 1954 divided Vietnam at the 17th Parallel, creating communist North Vietnam under Ho Chi Minh and anti-communist South Vietnam under Ngo Dinh Diem.
- Elections meant to unify Vietnam were never held when Diem refused, fearing a communist victory.
- The South Vietnamese government became increasingly authoritarian, prompting rebellion among peasants.
- North Vietnam supported the National Liberation Front (NLF) in the South, hoping to reunify the country.
- The United States viewed Vietnam through the lens of containment and the domino theory, escalating involvement.

The Formation of the National Liberation Front (NLF), 1960
Origins and Aims
- The NLF was formed to overthrow Diem and reunify Vietnam under a nationalist-communist government.
- It presented itself as a broad nationalist coalition, appealing to rural peasants suffering from Diem’s land policies.
- The NLF emphasized land reform, political autonomy and anti-imperialism.
- It operated through political cells embedded in rural communities.
- The organization became the central force challenging South Vietnamese authority.
Support from the North
- The NLF received weapons, training and guidance from Hanoi, strengthening its military capabilities.
- The Ho Chi Minh Trail provided secure supply lines through Laos and Cambodia.
- Northern support helped coordinate guerrilla and conventional operations.
- The NLF used propaganda to build legitimacy and portray itself as the voice of Vietnamese nationalism.
- The group’s strength contributed directly to American escalation after 1964.
