Angkor Kingdom Wars With the Chams

The Kingdoms of Angkor were aggressive war mongers which invaded and at times conquered large parts are now parts of modern Thailand, Laos and Vietnam.

• The Khmer Kingdom invaded the Mon Kingdom of Dvaravati in Thailand as discussed here. The Khmer Empire controlled what is now Thailand for hundreds of years.
  
• The also Khmer invaded the Vietnamese in what is now Vietnam.
  
• The Khmer invaded the Chams of the Kingdom of Champa in what is now Southern Vietnam.
• The first invasion of Champa was 1080 when Champa in its North was invaded at Vijaya and elsewhere. The purpose for the invasion was for the Khmer to loot treasures and capture slaves.
• In 1145 King Suryavarman II [ the founder of Angkor Wat ] invaded Vijaya and destroyed important Cham temples in My Son. In 1149 the Khmer were then expelled from Champa. In 1170 the Cham responded with no definitive success until 1177 when the Chams made a successful invasion by ships up the Mekong River and upstream to Tonle Sap Lake, south of Angkor and surprised the Khmer and defeated them at the then Capital of Yasodharapura [   ]. The Chams then looted and sacked the City and killed the Khmer King [  ], Scenes of these events are what are depicted in the murals of the Outer Gallery at Bayon Temple in Angkor Thom.
• In 1181 the new and successor Khmer King, Jayavarman VII, defeated the Chams. In 1190 again the Chams tried to invade and capture Angkor. This time led by the Cham King, Jaya Indravarman IV. He failed and was sent to Angkor as a captive. From 1190 the Khmer Empire tried to subjugate the Cham and by 1203 they succeeded making Champa a Province of Angkor until1220 when it regained independence.
