Who Fought in the Vietnam War?

From 1954 to 1975, the Vietnam War was fought between communist North Vietnam, supported by the Soviet Union and China, and non-communist South Vietnam, who were backed by the United States and its allies.

At the 1954 Geneva Conference, North Vietnam wanted to reunify the country into a full-on communist country, but the South resisted with backing from the American military.


Yet, the Geneva Accords split Vietnam into a communist North, led by Ho Chi Minh, and an anti-communist South, originally led by Ngô Dinh Diêm.


Because of this disagreement, the United States sent 2.7 million military personnel to Vietnam during the length of the war, from November 1, 1955, to April 30, 1975, to stop the spread of communism during the Cold War and provide financial aid, weapons, and military advisers to South Vietnam.


The war was one of the costliest and deadliest in modern history.


Furthermore, the United States spent $168 billion to $178 billion in direct costs during the Vietnam War.


Over the 20 years of fighting, three million Americans served in the conflict, but 58,220 American soldiers were killed.


Two million civilians died across the North and South; 1.1 million communist fighters died, and 200,000 military personnel from South Vietnam were killed.


The United States' involvement in Vietnam sparked nationwide anti-war protests and calls for a shift in the country’s foreign policy.


In 1975, the war ended when North Vietnamese forces captured Saigon on April 30, 1975, which led to the unification of a communist nation.


The United States, North Vietnam, South Vietnam, and the Viet Cong signed the Paris Peace Accords in January 1973, leading to U.S. military withdrawal.


Overall, the significance of the war ties into the demonstrations of military power limits, the impact of public opinion on government policy, and the long-term consequences for both Vietnam and the United States.
