Angkorian Warfare 1113-1220: The conflicts of the Khmer Empire from Suryavarman II to Jayavarman VII The Khmer Empire in what is today Cambodia came to rule almost all of Southeast Asia as one of the most powerful empires and warrior-monarchies of the 12th and 13th centuries. Even though the history of the period is elusive as there are few surviving wrien accounts, there are however several important historical military & warfare lessons which can drawn from the early Angkorian or Moha Nokor period. Historically it has been established that the Khmer Empire came to dominate great porons of the region between 1000-1432 AD, growing through conquest and the fostering of diplomacy to secure exisng and acquire new tributary territories. The Khmer (Angkorian Empire) at War. This Cambodian empire in Southeast Asia was predeceased by both the Funan and Chenla states which had been pey kingdoms exising before the 8th century, their power centering around the Mekong Delta. Dominated by three major ethnic groups, the Mon, the Cham and the Khmer peoples, the cultures of the region were most certainly warlike and by the 11-12th centuries the Khmer empire was on the move expanding north and south, east and west. As a result the Angkorian kings would be sporadically at war with other rival kingdoms throughout 1113-1229. Endemic warfare was waged on sea and land between the Khmer, Thai, Vietnamese, and the Cham kingdoms all vying for supremacy over Southeast Asia. China and later the Mongol hordes of Genghis Khan (b. aſter 1155-d.1227) and his successors would also play a major part in the pracce and connuaon of warfare and conflict in this region.
