Phagdrubpa Regime's Rule of Tibet in the 1430s

Timeline

1. 1431–1432Nechung · Ü-Tsang (Tsang)The tenth Gongma Dragön Gyaltsen still presided over Phagmodrupa affairs in the early 1430s, maintaining nominal jurisdiction over most of Ü-Tsang. In his later years his health declined and a transfer of power was imminent, while local forces seized the opportunity to expand their autonomy.
2. 1432–1437Ü-Tsang · TibetThe eleventh Gongma Dragön Drub acceded in 1432, and the Phagmodrupa regime entered a period of decline. The Gongma's actual control over Tsang and Ngari was insufficient; monastic groups and local nobles acted on their own, and the Phagmodrupa Kagyu's theocratic integration clearly weakened.
3. 1435–1440Tsang, between Tsetang and Shigatse · TsangThe Rinpungpa family steadily accumulated military and political resources in Tsang, forming an east-west standoff with Phagmodrupa in Ü-Tsang. By the late 1430s Tibetan politics showed Phagmodrupa, Rinpungpa, and various monastic schools coexisting multipolarly; Ming investiture and tributary titles continued, but real local power had shifted sharply downward.
