The first Vietnamese appeared in history as one of many scattered peoples living in what is now South China and Northern Vietnam just before the commencement of the Christian era. According to local tradition, the small Vietnamese kingdom of Au Lac, located in the heart of the Red River valley, was founded by a line of legendary kings who had ruled over the ancient kingdom of Van Lang for thousands of years. Historical evidence to substantiate this tradition is scanty, but archaeological findings indicate that the early peoples of the Red River Delta area may have been among the first East Asians to practice rice cultivation, and by the 1st century BC they had achieved a relatively advanced level of Bronze Age civilization.

During the centuries of Chinese domination over the Red River Delta, two independent states rose to power in what is now central and southern Vietnam . From the first to the sixth centuries, the kingdom of Funan held sway over the Mekong Delta and the region that is now Cambodia ; the kingdom was over thrown by the Mon-Khmer, who founded the Cambodian empire.

Along the coast of central Vietnam , the kingdom of Champa ruled from the late second century until the 15th, when it was conquered by the Vietnamese, who expanded steadily southward after expelling the Chinese. In the 17th and early 18th centuries, the Vietnamese would wrest the Mekong Delta from Cambodia , essentially completing the formation of their country.

Of the more than a dozen dynasties that have ruled independent Vietnam , three are considered "great." The first was the Ly (1009-1225), whose rulers established Hanoi as their capital in the year 1010, naming it Thang Long, the City of the Soaring Dragon. Under this dynasty, new roads, dikes, and canals were built and agriculture was vigorously promoted.

The Ly dynasty ended in overthrow by the Tran, who established the second great dynasty (1225-1400). In 1407, the Chinese re-conquered Vietnam , but this time their rule lasted only two decades. In 1428, they were driven out by the Vietnamese hero who established the third great dynasty, Le Loi. The Le dynasty, which was in power until 1524, introduced a series of remarkable reforms. Arts, literature, and education were promoted. Large landowners were forced to distribute their holdings to the poor. And particularly legal reforms gave women nearly equal rights to men.

In the 17th and 18th centuries, Vietnam was split by warring factions. Northern Vietnam was ruled by the powerful Trinh Lords while the south was under the control of lords of the Nguyen line. In 1786, the three Tay Son brothers, briefly reunited the country, but even as they fought to depose the Trinh and Nguyen lords, their empire began fragmenting.

In 1802, one of the Nguyen lords defeated the Tay Son and proclaimed himself King Gia Long, establishing the last of Vietnam 's dynasties. The Nguyen made Hue their imperial capital, and they ruled from there until the last Vietnamese King, Bao Dai, abdicated to a delegation representing Ho Chi Minh in 1945.

Vietnam 's contacts with the West began as early as A.D. 166, when Roman travelers passed through the Red River Delta. It wasn't until much later, however, that there was any sustained Western contact. By 1516, a number of Portuguese adventurers had arrived, followed by missionaries and soldiers. Over the next century a trading center and mission were established in the port of Phai Pho, just south of present day Da Nang . The Portuguese were followed by missionaries from Spain , Italy , and France . Everyone seemed intent on converting the Vietnamese, and in the process, cultivating stronger trading ties, but no one had much luck in making a profit from trade with the Vietnamese. The Dutch tried and failed, and the English was no exception.

The early French trading efforts were in vain as well, but the French never gave up. Off and on for nearly two centuries, the French kept lurking around Indochina . From about 1850s on, French abandoned diplomatic negotiations and settled on a policy of conquest. It would take them several decades, but by 1893 they had carved out an Indochinese empire that included Vietnam , Laos , and Cambodia .

The exploitation visited on the Vietnamese by their French masters created fertile conditions for the resistance movements that sprang up over the years. Most of the resistance efforts were successfully put down, but in 1925 a new movement was established by a man calling himself Nguyen Ai Quoc, who in later years would take the name Ho Chi Minh. Ho's Vietnam Revolutionary Youth League became the nucleus of the Vietnamese Communist Party. In World War II, Ho formed the League for the Independence of Vietnam, or Viet Minh.

The American support of the Viet Minh led Ho to believe that the United States would back his bid for an independent Vietnam . But after the war, the Allies allowed France to reoccupy Indochina, setting the stage for the protracted guerrilla campaign that resulted in France 's ouster in 1954 and the subsequent partitioning of Vietnam into North and South. The recognition and support of South Vietnam by the United States would lead to the bloody conflict that ended in 1975 when the Communists overran Saigon , proclaiming an independent Socialist Republic of Vietnam.
