Royal centres and their hinterlands
From the ninth century, Khmer rulers built capitals and temples north of the Tonle Sap lake. Angkor developed a dense network of settlements and fields. Appointments, tribute and donations connected the court with local communities. Temple inscriptions record land, supplies, workers and patrons. Royal projects brought together stoneworkers, transport labourers and other artisans, while farming sustained the population living among temples, ponds and cultivated land across the wider urban landscape.
Managing water and building temples
Reservoirs, channels and embankments managed seasonal water and supplied settlements and fields. Successive rulers altered the network and placed temples within planned landscapes. Twelfth-century Angkor Wat and the later Angkor Thom and Bayon preserve distinct phases of royal and religious patronage. Their reliefs show warfare, ceremonies and daily activities. Channels required clearing and buildings required repair, tying monumental construction to continuing decisions about labour, agricultural resources and regional organization.
Environmental pressures and relocation
Droughts and intense rainfall placed pressure on the water network during the fourteenth and fifteenth centuries. Warfare and changing commercial opportunities also affected royal choices. Political activity moved toward areas connected with the Mekong and maritime exchange, while parts of Angkor’s settlement landscape contracted. Temples remained in use. Archaeological survey, remote sensing and inscriptions now trace old roads, channels and residences, revealing successive adjustments in settlement, labour and environmental management.
