Desi Sangye Gyatso
Tibetan regent

Kalon Sangye Gyatso (1653–1705) was the sixth regent of the 5th Dalai Lama (1617–1682), in the Ganden Phodrang government. He founded the Chagpori College of Medicine in 1694, a Traditional Tibetan medicine school for monks which grew in 1916 under the 13th Dalai Lama to include Astrology and Astronomy departments collectively called the Men-Tsee-Khang. He wrote the Blue Beryl (Blue Sapphire) medical treatise, and illustrated medical thankas. His name is sometimes written as Sangye Gyamtso and Sans-rGyas rGya-mTsho
In some accounts, Sangye Gyatso is believed to be the son of the "Great Fifth", but he was born near Lhasa in September 1653, when the Dalai Lama had been absent on his trip to China for the preceding sixteen months. He ruled as the Kalon (regent) of the Dalai Lama and under his instructions hid the death of the Dalai Lama for 15 to 16 years while the infant 6th Dalai Lama was growing up. During this period, he oversaw the completion of the Potala Palace, and warded off Chinese politicking.
He is also known for harboring disdain for Tulku Dragpa Gyaltsen, although this monk died in 1656 when Sangye Gyatso was only three years old. According to Lindsay G. McCune in her 2007 thesis, Sangye Gyatso refers in his Vaidurya Serpo to the monk as the "pot-bellied official" (nang so grod lhug) and states that following his death, he had an inauspicious rebirth.
Chagpori College of Medicine
Sangye Gyatso founded the Chagpori College of Medicine in 1694, under the commission of the 5th Dalai Lama. The college was designed for monastic scholars who would, after learning esoteric arts of medicine and tantrism serve the public as would other monk scholars and lamas.

Why this record matters
The phrase “tibetan regent” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Apr 18, 2026. The linked authority identifier is Q1387854. VIAF identifies the subject as 5104415. The Library of Congress control number is n80017688. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1653, 1705, 1617 and 1682.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
