From dynasty to republic
Tibet is located in Southwest China. The people who lived there struck up links with the Han in the Central Plains long before the Christian era. Throughout centuries, the numerous tribes scattered across the Qinghai-Tibet Plateau gradually developed into the Tibetan ethnic group.
By the Tang Dynasty (AD 618-907), the Tibetans and Hans had, through marriages between royal families and other alliances, cemented unity and political friendship and formed close economic and cultural relations. This created a solid foundation for the ultimate founding of a unified nation.
A statue of the Tang Princess Wencheng, who married the Songtsan Gambo, the Tubo king, in 641, is still enshrined and worshiped at the Potala Palace in Lhasa, capital of the Tibet autonomous region.
