Timeline

1. 1221–1225Sakya · SakyaUnder the direction of Gö Sangtsa, the Sakya school expanded Sakya Monastery, managing its estates through a model combining hereditary family rule with monastic office. The monastery collected tenant rents, hosted religious assemblies, and trained scholar-monks versed in Sanskrit and Tibetan texts, extending its influence from Tsang into Ü-Tsang.
2. 1222–1228Lhasa · LhasaKagyu branch monasteries such as Drigung and Phagmodru maintained meditation lineages and local arbitration authority around Lhasa. The monastery system centered on master-disciple transmission, treasure texts, and tantric empowerments, forming a joint rule of religion and state with secular lords.
3. 1229–1230Ü-Tsang region · Ü-TsangMonasteries of various sects held estates and followers across Ü-Tsang, with the Sakya school gaining an edge through its knowledge of Mongol language and diplomatic experience. The economic base of the monastery system and the monastic organization provided the institutional conditions for the Mongol Empire to later choose Sakya as its agent for all of Tibet.
