On what was Khmer prosperity based?

Khmer prosperity was primarily based on agriculture, particularly rice cultivation, supported by an extensive irrigation system that allowed for multiple harvests each year. The civilization also thrived on trade, leveraging its strategic location to engage in commerce with neighboring regions and cultures. Additionally, the Khmer Empire's architectural and artistic achievements, exemplified by monumental structures like Angkor Wat, reflected and reinforced its economic strength and cultural identity.
