South Vietnam (Client state during the Vietnam War)

South Vietnam was a country in Southeast Asia, established in 1955, supported by the United States and allies during the Vietnam War. It aimed to prevent the spread of communism from the neighboring North Vietnam. South Vietnam's government was democratic but faced internal corruption and political instability. The country was seen as a client or proxy state, meaning it relied heavily on U.S. military and economic aid. The conflict ultimately ended in 1975 when North Vietnam unified the country under communist control after South Vietnam fell to advancing North Vietnamese forces.
