The Tibetan Kings were a series of rulers who governed Tibet from the 7th to the 9th centuries. The most notable among them was Songtsen Gampo, who is credited with unifying Tibet and introducing Buddhism to the region. His reign marked the beginning of a significant cultural and religious transformation in Tibetan society. These kings established a centralized government and promoted trade and diplomacy with neighboring regions, including China and India. The period of the Tibetan Kings is often seen as a golden age for Tibetan culture, as it laid the foundation for the development of Tibetan identity and the spread of Buddhism throughout the Himalayas.
