AngkorAngkor (អង្គរ ʔɑŋkɔː, 'Capital city'), also known as Yasodharapura (យសោធរបុរៈ; यशोधरपुर), was the capital city of the Khmer Empire. The city and empire flourished from approximately the 9th to the 15th centuries. The city houses the Angkor Wat, one of Cambodia's most popular tourist attractions. The name Angkor is derived from nokor (នគរ), a Khmer word meaning "kingdom" which in turn derived from Sanskrit nagara (नगर), meaning "city".
ChampaChampa (Cham: ꨌꩌꨛꨩ; ចាម្ប៉ា; Chiêm Thành 占城 or Chăm Pa 占婆) was a collection of independent Cham polities that extended across the coast of what is present-day central and southern Vietnam from approximately the 2nd century AD until 1832. According to earliest historical references found in ancient sources, the first Cham polities were established around the 2nd to 3rd centuries CE, in the wake of Khu Liên's rebellion against the rule of China's Eastern Han dynasty, and lasted until when the final remaining principality of Champa was annexed by Emperor Minh Mạng of the Vietnamese Nguyễn dynasty as part of the expansionist Nam tiến policy.

Historians call this period of Cambodian history the Angkor period, after the empire's most well-known capital, Angkor. The Khmer Empire ruled or vassalised most of mainland Southeast Asia and stretched as far north as southern China.
