The Democratic Republic of Vietnam (DRVN) (Vietnamese: Việt Nam Dân Chủ Cộng Hòa), also known as North Vietnam, was a country that existed from 1945 until 1976. It took control in northern Vietnam and eventually took over its southern opponent. It lay north of the local Demilitarized Zone, and South Vietnam lay to the south of it.
It was proclaimed by President Hồ Chí Minh in Hà Nội on September 2, 1945. The country was supported by China and the Soviet Union during the Vietnam War, eventually defeating South Vietnam 20 years later.
