Decline of Srivijaya

Timeline

1. 1121–1125Southeastern Sumatra · SumatraSrivijaya's central royal authority could hardly effectively govern distant vassals; local chiefs and port-city powers went their own way, and the empire's nominal suzerainty was seriously divorced from its actual control.
2. 1123–1129Strait of Malacca · Strait of MalaccaSong, Champa, and Javanese merchant ships increasingly chose emerging ports for transshipment; Srivijaya's traditional toll and escort revenues plummeted, and the commercial monopoly base on which the maritime empire depended was shaken.
3. 1125–1130Eastern Java · JavaEmerging Javanese kingdoms such as Kedari rose in power, contesting Srivijaya's remnants at spice-producing areas and shipping nodes, accelerating the disintegration of the old sea power system and the redrawing of Southeast Asia's political map.
