This is the first time an archaeobotanical analysis based on macroremains, both charred and desiccated, from Cambodia is reported. The archaeobotanical samples are rich and provide evidence of rice processing, consumption of non-indigenous pulses, and the use of economic crops. The evidence is supported by data from inscriptions, texts and historical ethnography. This study demonstrates that the city of Angkor in the 14th and 15th centuries CE, despite its decline, was still occupied. Angkor's inhabitants continued their everyday lives cultivating and consuming their staple food, rice, with a suite of pulses, and also used the harvests in the performance of rituals.
