Timeline

1. c. 1240–1289Sakya · Sakya CountyAfter Phags-pa established the administrative system of the thirteen myriarchies, the dpon-chen became the lay leader managing Tibet's daily government under the imperial preceptor. Aglen had previously held various Sakya administrative posts and rose gradually into the line of dpon-chens; earlier holders included Jangdo (in office in 1289).
2. 1290–1294Sakya · Sakya CountyAround 1290 he became the ninth dpon-chen, managing the affairs of the thirteen myriarchies under the Pacification Commission of Ü-Tsang, Ngari and Sughchil on behalf of the imperial preceptor. The dpon-chen was appointed and sealed by the Yuan emperor and was responsible to the imperial preceptor, holding actual secular administrative and military power in Tibet.
3. 1290Drigung Monastery · Maizhokunggar CountyIn 1285 the Drigung sect rose against Sakya rule with support from Duwa of the Chagatai Khanate. In 1290 Aglen led Sakya and Yuan forces (those of Temür Buqa) to besiege Drigung Monastery, burning the monastery and killing its people; the rebellion was completely crushed and the Yuan–Sakya system of co-rule was consolidated.
4. 1294–1298Sakya · Sakya CountyAfter Kublai Khan's death, in 1294 Aglen convened a meeting of Sakya officials and proposed recalling the Khön kinsman Dagny Chenpo Sangpo Pal (Phags-pa's nephew), then under house arrest in Jiangnan, to head Sakya. Temür, Emperor Chengzong of Yuan, approved, and Sangpo Pal returned to Tibet in 1298 to succeed as Sakya leader; Aglen's term as dpon-chen ended around that year.
