* The French colonial period: Vietnam was a French colony from the late 19th century until the mid-20th century. During this time, there was growing discontent among Vietnamese people who wanted independence from French rule.
* The rise of communism in Vietnam: In the early 20th century, communism began to spread in Vietnam. The Communist Party of Vietnam (CPV) was founded in 1930, and it quickly became a major force in the Vietnamese independence movement.
* The Geneva Accords: In 1954, the Geneva Accords were signed, which divided Vietnam into two countries: North Vietnam and South Vietnam. The CPV controlled North Vietnam, while the South was controlled by a US-backed government.
* The Gulf of Tonkin incident: In 1964, the United States Navy claimed that North Vietnamese torpedo boats had attacked two US destroyers in the Gulf of Tonkin. This incident led to the US Congress passing the Gulf of Tonkin Resolution, which authorized the US president to use military force in Vietnam.
* The US escalation of the war: In the years following the Gulf of Tonkin incident, the US military presence in Vietnam increased dramatically. The US launched a bombing campaign against North Vietnam, and it also sent ground troops into the country.
The Vietnam War lasted for over 20 years and resulted in the deaths of millions of people. It was a tragic conflict that had a profound impact on both Vietnam and the United States.
