Power Transition in the Angkor Empire

Timeline

1. 1220–1221Angkor · CambodiaJayavarman VII had already reduced foreign campaigning late in his reign; his death deprived the empire of a strong personal authority center. Brief tensions arose within the royal family over succession and regency, while provincial governors and temple economic powers seized the chance to expand their autonomy.
2. 1221–1223Angkor · CambodiaIndravarman II acceded around 1220–1221, attempting to continue the previous Buddhist state system, but was unable to replicate the large-scale military mobilization and construction projects of Jayavarman VII's era. Court ritual and the tribute system still functioned, yet central authority was markedly weaker than at the empire's height.
3. 1223–1230Territory of the Angkor Empire · Eastern ThailandBy the 1220s, Angkor's control over Champa and the western frontier declined, and tax-exempt temple estates kept expanding, eroding the tax base. The empire appeared unified but was actually transitioning from rule by a strong individual monarch to oligarchic co-rule by local powers.
