advice was eventually accepted. Tibetan sources suggest that the Guge population was maintained in their old status. The last king, Tashi Drakpa De, (Khri bKra shis Grags pa lde) and his brother and other kin, were deported to Ladakh, where they lived comfortably until their death. The prince married a wife from the Ladakhi royal family. Annexation to Central Tibet Tsaparang and the Guge kingdom were later conquered in 1679–80 by the Lhasa-based Central Tibetan government under the leadership of the 5th Dalai Lama, driving out the Ladakhis. Historiography Western archeologists heard about Guge again in the 1930s through the work of Italian Giuseppe Tucci. Tucci's work was mainly about the frescoes of Guge. Lama Anagarika Govinda and Li Gotami Govinda visited the kingdom of Guge, including Tholing and Tsaparang, in 1947–1949. Their tours of central and western Tibet are recorded in black-and-white photos.
