Late-period Angkor capital

Timeline

1. 1431Angkor · CambodiaSiamese armies captured Angkor; the Khmer royal court and administrative center moved south to Phnom Penh, Lovek, and elsewhere, and Angkor shifted from imperial capital to a post-decline religious and local stronghold, marking the end of the classical Angkor capital system.
2. 1461–1470Angkor monuments · CambodiaBy the 1460s Angkor was no longer the empire's political center, but temple maintenance, resident monks, and local fiefs continued; the Khmer kingdom rebuilt its authority at Phnom Penh, while Angkor became a symbolic sacred city and a late-capital remnant in archaeological terms.
3. c. 1600Angkor · CambodiaBy around the 16th century, Angkor's urban population had sharply declined, hydraulic systems fell into disrepair, and large temple areas were covered by jungle; the capital essentially ceased to exist as a functioning urban entity, awaiting later rediscovery and study.
