An Overview of the Vietnam War

Click on an entry to see the details.

  1. French colonial rule and the background to the country's division

    Vietnam, under French colonial rule, declared independence after World War II but fought an eight-year war with France (the First Indochina War); when France was defeated in 1954, the Geneva Accords were signed. Under this agreement, Vietnam was provisionally divided along the 17th parallel into communist North Vietnam and pro-Western South Vietnam.

  2. The Gulf of Tonkin incident and US intervention (1964)

    As the South Vietnamese government grew unstable amid the spread of communist guerrillas (the Viet Cong), the United States increased its support by dispatching military advisors, among other measures; then, following the Gulf of Tonkin incident in 1964 β€” in which a US Navy vessel was reported to have been attacked by North Vietnam β€” the US began deploying troops in earnest, directly intervening in the war.

  3. The nature of the guerrilla warfare

    North Vietnamese forces and the Viet Cong confronted the heavily armed US military using guerrilla tactics that exploited the jungle and an underground tunnel network. This style of fighting, rather than conventional warfare, inflicted heavy losses on US forces and prolonged the war.

  4. The spread of antiwar sentiment within the United States

    As the war dragged on and casualties mounted, antiwar sentiment spread rapidly within the United States after the 1968 Tet Offensive, as the horrors of the war became known through television. Large-scale antiwar protests, centered on college campuses, deeply divided American society.

  5. The Paris Peace Accords and the withdrawal of US forces (1973)

    With the signing of the Paris Peace Accords in January 1973, US forces withdrew from Vietnam. However, this was not a complete end to the war, and fighting between North and South Vietnam continued.

  6. The fall of Saigon and reunification (1975)

    North Vietnamese forces, which continued the war even after the US withdrawal, captured Saigon, the capital of South Vietnam, on April 30, 1975. The following year, in 1976, North and South Vietnam were officially reunified as a single socialist republic.

A Cold War proxy war and its devastation

The Vietnam War was not simply a civil war β€” it was a representative Cold War-era proxy war involving the free-world camp, led by the United States, and the communist camp, including the Soviet Union and China. Ending with the fall of Saigon in 1975, this war left millions of casualties and had a profound impact on both American society and the international situation.

After the Vietnam War, decolonization trends on another continent

The process by which Vietnam broke free from French colonial rule and achieved independence and reunification connects with the decolonization trends that unfolded on other continents around the same time. Looking together at our guide to Africa's colonization and independence process, in which African nations broke free from European colonial rule in the mid-20th century, can help you understand the broader currents of world history at the time.

Frequently Asked Questions

Did the Gulf of Tonkin incident actually happen?

When it was announced in 1964, the United States stated it had been attacked by North Vietnam, but later declassified records raised controversy and allegations of exaggeration regarding some of the details of the incident. That said, it is a clear historical fact that this incident triggered the United States' full-scale military involvement in the war.

Did South Korean troops also take part in the Vietnam War?

Yes. At the request of the United States, South Korea began by dispatching medical personnel and taekwondo instructors in 1964, and from 1965 onward sent combat troops, including the Tiger and Blue Dragon divisions, in earnest. South Korea's participation in the war is regarded as a significant event in modern history that left lasting effects on both South Korea-US relations and the South Korean economy.
