Sakya School Invested by the Mongols (1240s)

Timeline

1. 1244–1245Sakya Monastery · TibetPrince Godan wrote to Sakya Pandita, inviting him to Liangzhou through a combination of Mongol military pressure and religious dialogue. The Pandita judged that the Sakya school should proactively cooperate with the Mongols to preserve Tibet, and decided to set out, bringing along his young nephew Phagpa.
2. 1246–1247Liangzhou · GansuAfter arriving in Liangzhou, Sakya Pandita met with Godan, explaining that Tibetan submission to the Mongols could spare them slaughter and preserve their religion and people's peace. The Pandita composed the Sakya Pandita's Letter to the Tibetans, requiring all Tibetan factions to pay tribute and submit to the Mongols, acknowledging the Sakya school as the Mongol-appointed agent.
3. 1247Liangzhou · GansuThe talks' outcome was implemented as a political arrangement: the Sakya school oversaw taxation, household registration, and local order in Tibet, while the Mongols retained suzerainty and military deterrence. This model laid the institutional foundation for Phagpa's later investiture by Kublai Khan and the establishment of the Ü-Tsang Nari Xuanwei Commission.
