The Kingdom of Cambodia is a country in Southeast Asia with a population of over 14 million people. Cambodia is the successor state of the mighty Khmer Empire, which ruled most of the Indochinese Peninsula between the 9th and 14th centuries.
Angkor is a name conventionally applied to the region of Cambodia serving as the seat of the Khmer Empire that flourished from approximately the 9th century to the 15th century A.D. (The word "Angkor" itself is derived from the Sanskrit "nagara," meaning "city.") More precisely, the Angkorian period may be defined as the period from 802 A.D., when the Khmer Hindu monarch Jayavarman II declared himself the "universal monarch" and "god-king" of Cambodia, until 1431 A.D., when Thai invaders sacked the Khmer capital, causing its population to migrate south to the area of Phnom Penh.
The ruins of Angkor are located amid forests and farmland to the north of the Great Lake (Tonlé Sap) and south of the Kulen Hills, near modern day Siem Reap (13°24'N, 103°51'E), and are a UNESCOWorld Heritage Site. The temples of the Angkor area number over one thousand, ranging in scale from nondescript piles of brick rubble scattered through rice fields to the magnificent Angkor Wat, said to be the world's largest single religious monument. Many of the temples at Angkor have been restored, and together they comprise the most significant site of Khmer architecture. Visitor numbers approach one million annually.
