The Khmer Empire and Angkor
In the jungles of Southeast Asia, the Khmer Empire built Angkor, the largest pre-industrial city the world has ever known — a capital of perhaps 750,000 people, sustained by a vast, ingenious web of canals and reservoirs. Its crowning temple, Angkor Wat, remains the largest religious monument on Earth. The Khmer reveal the same pattern that raised Egypt and the Maya: a state able to marshal enormous coordinated labor around water, faith, and a god-king.
A durable new order — a state, an institution, a system of rule — is deliberately built and consolidated, outlasting the people who founded it.
