Cambodia's topography has played a significant role in shaping the country's history. The country's strategic location at the crossroads of Southeast Asia has made it an attractive place for traders, invaders, and settlers. The Angkorian Empire, which ruled Cambodia from the 9th to the 15th century, built its capital city, Angkor Wat, in the northwestern part of the country, near the Tonle Sap lake. The empire's extensive irrigation system, which connected the lake to the rice paddies and agricultural areas, allowed for the growth of a large and prosperous population.
