Decline of the Angkor Dynasty in the 1320s

Timeline

1. 1321–1325Angkor Thom · Siem ReapIn the early 1320s, the Angkor court's ability to levy taxes and mobilize troops in the provinces declined markedly, and large-scale temple and hydraulic works nearly ceased, reflecting that state finances and labor systems could no longer sustain the empire's scale.
2. 1324–1328Western and northern Khmer frontiers · CambodiaIn the mid-to-late 1320s, border conflicts were frequent with Siamese forces in the west and Champa in the east; Khmer armies could hardly strike back effectively, and frontier provinces gradually slipped from direct central control.
3. 1327–1330Angkor and the lower Mekong · CambodiaBy the late 1320s, court infighting and the separatism of local strongmen further shook Angkor's status as a unified political center, while the lower Mekong region rose in importance, foreshadowing a later eastward shift of political gravity.
