Vietnam del Norte, or North Vietnam, was a region in Southeast Asia that existed from 1954 to 1976. It was officially known as the Democratic Republic of Vietnam and was governed by a communist regime. The capital city was Hanoi, and the government aimed to unify the country under its communist ideology. North Vietnam played a significant role in the Vietnam War, fighting against South Vietnam and its allies, including the United States. The conflict ended in 1975 with the fall of Saigon, leading to the reunification of Vietnam in 1976, officially known as the Socialist Republic of Vietnam.
