The Angkorian Khmer Economy

Angkor, near modern Siem Reap in northwestern Cambodia and north of Tonle Sap Lake, supported a large inhabited landscape from the ninth to fifteenth centuries CE. Rice fields, waterworks, households, temple foundations, workshops and markets met different needs across the capital region and its hinterland. Their connections appear in field layouts, endowed land and labor, workshop remains, inscriptions and a visitor’s account of Angkor in 1296–1297.

Fields, harvests and temple foundations

Farmers grew rice in varied settings around Angkor. At Pre Rup, a tenth-century temple near the Angkor core, a grid of square plots was laid out; in the northwest hinterland, fields followed streams and older channels. Small raised banks, or bunds, helped hold water around paddies. These settings show cultivation adapted to planned layouts as well as local terrain. Rice had to be harvested and processed before it could be eaten or stored. Excavated rice husks and spikelet bases, the parts that attach individual grains to the rice head, at Angkor Wat and Ta Prohm indicate that people dehusked grain in lived-in temple enclosures.

Land also supported religious institutions. A twelfth-century inscription from Daun Onn describes a temple estate with a common field whose harvest went to the foundation, land for servants, a field for the chief priest and plots to feed dependent workers. Two work teams alternated between the common field and their own food plots during a lunar month. The record shows how endowed land joined ritual supply with the upkeep of people serving a temple. Other inscriptions record particular arrangements, including purchases, village land sales, boundary marking and assignments of produce or service.

Water linked farms, settlements and sacred places

Angkor’s waterworks formed through successive projects. Rainfall and river flow changed with the monsoon, so embankments, canals, field bunds and ponds managed water at different scales. Local ponds and field channels supported nearby settlement and cultivation; large barays, reservoirs enclosed by embankments, formed part of a broader urban water landscape. Major reservoirs and distributors were built or modified over centuries, and their channels also served moats and temple settings.

The West Mebon, a temple to Vishnu on an artificial island, stood within the eleventh-century West Baray. Water gave the sanctuary its setting as well as shaping movement to the island. Maintaining earthen banks and channels meant dealing with sediment and erosion. In a model of Angkor’s thirteenth-century network, heavy flood flows can deepen one branch, draw water away from another and increase sediment where flow weakens. The model illustrates how connected channels could become vulnerable; archaeological evidence also records local changes, including a reconfigured outlet at the East Baray. These works were maintained and altered as conditions and urban needs changed.

Household and specialist production

Economic production took place in homes, temples and specialized work areas. Plant remains from Angkor Wat and Ta Prohm include rice-processing waste, mung beans and cotton seeds. Cotton bolls are seedpods that carry the fibers used to make thread; the recovered seeds indicate that bolls were brought to these locations and fibers could be prepared for textile work. Zhou Daguan, who visited Angkor in 1296–1297, describes cotton yarn and weaving, including work using a loom tensioned against the weaver’s body. His account gives a dated view of textile production in the capital.

Other crafts left different evidence. Repeated kiln chambers at Chong Samrong, in Siem Reap province, preserve vents, firing trenches, stoneware jars and vessels that collapsed or remained underfired. Stoneware is a hard ceramic produced by high-temperature firing. The succession of chambers shows potters reusing and adapting firing structures, while failed wares reveal the challenge of controlling heat. Near the royal palace, an eleventh-century foundry, a metalworking and casting workshop, left melting vessels, moulds and metal debris. Bronze is an alloy of copper and tin. Workers heated crucibles with charcoal. In lost-wax casting, a wax model coated in clay was heated until the wax melted and drained away. Workers poured molten bronze into the hollow mould, then removed the clay after the metal cooled and finished the cast parts. Inscriptions also assign workers and workshops to temple foundations, while excavated houses show production in domestic settings.

Markets, payments and exchange

Zhou’s description of Angkor’s market offers a late-thirteenth-century snapshot. Women sold goods from mats; small purchases could be paid for in rice, grain or Chinese goods, while larger transactions involved cloth, gold or silver. He also lists Chinese imports such as silk and porcelain. This account shows several means of exchange operating side by side in one market setting.

Inscriptions reveal other routes by which goods changed hands. A collective land sale recorded in 1042 lists textiles, animals and metal objects among payments. A late-twelfth-century Ta Prohm record names a weaver’s shop, villages and a market as sources of clothing and produce for the temple. Endowments, land payments and market purchases were distinct arrangements, even when they involved similar goods. Roads and waterways carried people and supplies among Angkor, regional centers and the coast; forest products such as beeswax, aromatic woods and resins also moved through these networks.

After the mid-fifteenth-century Ayutthaya occupation of Angkor, Cambodians moved their political center south to the Phnom Penh region, a river port connected with Mekong and Tonle Sap routes. Historian Michael Vickery links this shift with growing Chinese trade contacts and presents commercial rivalry as a possible factor.
