Originally the capita1 of the Tubo Kingdom, Lhasa dates back at least 1300 to 1400 years. The history of human settlement in the Lhasa area, according to archeological findings so far, is as long as 3,000 or 4,000 years, with the oldest evidence of habitation being the Neolithic Chugong Ruins on the northern bank of the Lhasa River. To wards the end of the Neolithic period, metal wares began to appear. In A. D. 633, Songtsan Gampo united all the tribes on the Qinghai-Tibet Plateau, and established the Tubo Kingdom as a slave society. The chiefs of the various tribes met and chose Rasa (present-day Lhasa) to be the capital. It seems to have been a well-wooded and well-watered place at that time. The land was fertile, and there was plenty of game to be hunted. The heyday of the Tubo Kingdom was during the reign of Trisong Detsen (742--797), the fifth king.
The original name of Lhasa was Wotang. The word Rasa, which often appears in historical records, literally means "goat" and "earth." It probably refers to the legend that goats carried earth to build the Jokhang Monastery. The name Lhasa (literally "sacred land") came into being later, when Buddhism became the dominant religion in Tibet.
The establishment of Lhasa as the capital by Songtsan Gampo symbolized the end of strife between the different Tibetan tribes. People started to live a peaceful, settled life, and rules for society were drawn up. The social progress made during this period can be detected at various archeological sites: the cliff carvings at Chakpori (Medicine King) Hill, the Tralhalupuk Grottoes, the ruins of Pabongka, where the Tibetan script was created by Thonmi Sambhota, and others. Such data attest to the great material and social progress made in that period, and show that early Tibetan history paralleled what was happening in the Central Plains at roughly the same time. previous to the establishment of the Tubo Kingdom, there had been a period of strife among the Tibetans similar to that of the Central Plains before Emperor Qin Shihuang (first emperor of the Qin Dynasty) unified China and ended the Chaos of the Spring and Autumn (770-476 BC)and the Warring States (4767211 BC) periods. This was well summed up by an elderly official of the Tibet Archives whom I met during my trip there: "When the Interior Land is prosperous and powerful, Tibet is peaceful. When the Interior Land is in chaos, Tibet is in upheaval."
The Tubo Kingdom lasted for 300 to 400 years. when it collapsed, Tibet was ruled by contending chieftains from 969 to 246. During the Song Dynasty (960-1279), which was a weak power, all that remained of connections between Tibet and the Central Plains seems to have been limited to trade in tea and horses. During the Sagya Period, in 13th century, when Tibet's political center moved westward, Tibet was officially incorporated into the territory of China's Yuan Dynasty. Some 130,000 clans in Tibet were given noble titles. Lhasa became one of the manorial estates bestowed on a man named Tshe-sbang, who was head of 10,000 households. The manorial system was abolished during the Ming Dynasty (1358-1644), but an administrative office was set up in Lhasa, and a policy of "giving more honorific noble titles and pooling more efforts for building the town" was adopted. The Qing Dynasty (1644-1911) court fostered and supported the Gelug Sect of Tibetan Buddhism, which was centered and rose in Lhasa more than 600 years ago, and encouraged the formation of a theocratic socio-politicla structure. The grand monasteries of Drepung ('Bras-spungs), Gandan (Dga'-ldan) and Sera were built in Lhasa in this period. With the backing of the Qing court, Lozang Gyatso (1617-1682), the fifth Dalai Lama, was the first autocrat under this new system, which lasted up until the mid-20th Living Buddha Demo, born in 1901.
