Kingdom of Dêgê

The Kingdom of Derge was an important kingdom in Kham from the 15th to the 19th century. It was a center of industry, religion and politics, with the seat of its kingdom in the town of Degé. The kings of Derge followed a 1300-year lineage.

At its height, the population of the kingdom consisted of 12-15,000 families. The northern border of the kingdom was defined by Qinghai Lake; on the east, the boundary terminated at those states that utilized the Horpa variation of the Rgyalrongic languages, Chantui and Litang; the southern and western boundaries were defined by Batang, Sanai, Gonjo and Draya; and Lhato and Chamdo, respectively.

The kingdom was known for its metal working and was an important center in the establishment of the Rimé movement in Tibetan Buddhism. The royal family of Derge were known as supporters of art, producing such artists as Situ Panchen, the kingdom's senior court chaplain, who is also known for his contributions to medicine and religion. Regent Queen Tsewang Lhamo (d. 1812) was known for her support of printing and publishing.

Degé became the capital of the kingdom in the 15th century under the reign of Lodro Tobden, the 31st in the line of the Derge kings. It was he who invited Thang Tong Gyalpo to establish the renowned Gongchen Monastery in the region. The kingdom expanded during the 18th century under the reign of Tenpa Tsering, who conquered territories to the north.

In 1727, the Kingdom of Derge and other regions in Eastern Tibet fell under the governance of China. It is linked with others of the "more important districts", as Spencer Chapman termed them, such as Nyarong, Batang, Litang, and the five Hor[pa] States under the name "Kham", which Chapman describes as "an indefinite term suitable to the Tibetan Government, who are disconcertingly vague over such details as treaties and boundaries." In 1733. The Yongzheng Emperor granted the king of Derge status of Hsuan Wei Ssu, a high position for native chieftains which effectively permitted him independence, though he was responsible for paying tribute. In spite of the change of provenance, the kings of the region continued their internal struggles, and in 1863, rule of the kingdom was disrupted for two years by the successful invasion of Nyarong. Intervention by the army of Tibet restored the kingdom, following a brief intermediate governance.
