Vietnam

A distinct Vietnamese group began to emerge c. 200 BCE in the independent kingdom of Nam Viet, which was later annexed to China in the 1st century BCE. The Vietnamese were under continuous Chinese control until the 10th century. The southern region was gradually overrun by Vietnamese from the north in the late 15th century. The area was divided into northern and southern dynasties in the early 17th century, and in 1802 these two parts were unified under a single dynasty. Following several years of attempted French colonial expansion in the region, the French captured Saigon (now Ho Chi Minh City) in 1859 and later the rest of the area, controlling it until World War II (see French Indochina). The Japanese occupied Vietnam in 1940–45 and allowed the Vietnamese to declare independence at the end of the war, a move the French opposed. The First Indochina War ensued and lasted until French forces with U.S. financial backing were defeated by the Vietnamese at Dien Bien Phu in 1954; evacuation of French troops followed. After an international conference at Geneva (April–July 1954), Vietnam was partitioned along latitude 17° N, with the northern part under the communist leadership of Ho Chi Minh and the southern part under the U.S.-supported former emperor Bao Dai; the partition was to be temporary, but the reunification elections scheduled for 1956 were never held. An independent South Vietnam (Republic of Vietnam) was declared, while the communists established North Vietnam (Democratic Republic of Vietnam). The activities of North Vietnamese guerrillas and procommunist rebels in South Vietnam led to U.S. intervention and the Vietnam War. A cease-fire agreement was signed in 1973 and U.S. troops withdrawn, but the civil war soon resumed; in 1975 North Vietnam invaded South Vietnam, and the South Vietnamese government collapsed. In 1976 the two Vietnams were united as the Socialist Republic of Vietnam. From the mid-1980s the government enacted a series of economic reforms and began to open up to Asian and Western nations. In 1995 the U.S. officially normalized relations with Vietnam.
