How big were the world’s ancient cities? At its height, the world’s first city of Uruk may have had about 40,000 people about 5,000 years ago. In the medieval period, London may have had a population of about a quarter of a million people, growing to approximately 600,000 by the early 17th century.
One of the world’s largest ancient cities lay in the jungles of Southeast Asia in the greater Angkor region located in contemporary Cambodia. This medieval site was home to the Angkor or Khmer Empire from the ninth to 15th centuries. You might be familiar with the famous Angkorian temple, Angkor Wat, one of the largest religious monuments in the world.
