Kingdom of Derge
The Kingdom of Derge (Tibetan: སྡེ་དགེ་, Wylie: sde dge; Chinese: 德格王國) was a large kingdom in Kham, whose estate was founded in the 13th century by the Gar Clan of Sonam Rinchen in present-day Pelyul County. The Gar Clan traces its lineage to minister Gar Tongtsen at Songsten Gampo's 7th century court, and the kingdom lasted until the 20th century.
