The Battle of Tonlé Sap (, , ) was a conflict between Champa and the Khmer Empire in 1177.The Bayon bas-relief depicts a battle on the Tonlé Sap lake, Angkor Thom

History The 12th century was a time of conflict and brutal power struggles. Under Suryavarman II (reigned 1113–1150), the Khmer Empire united internally, and the largest temple of Angkor, Angkor Wat, dedicated to the god Vishnu, was built over a period of 37 years. In the east, Suryavarman's campaigns against Champa and An Nam were unsuccessful, though he did sack Vijaya in 1145 and deposed Jaya Indravarman III. The Khmers occupied Vijaya until 1149, when they were driven out by Jaya Harivarman I. Suryavarman II sent a mission to the Chola dynasty of south India and presented a precious stone to the Chola emperor Kulothunga Chola I in 1114.

Another period followed in which kings reigned briefly and were violently overthrown by their successors. Finally in 1177, the capital of Angkor was raided and looted in a naval battle on the Tonlé Sap lake by a Cham fleet under Po Klong Garai, king of Panduranga, during which the king of Angkor, Tribhuvanadityavarman, was killed. Po Klong Garai established a new king of Champa, with the title of Jaya Indravarman IV.

Between 1177 and 1181, when he was in his mid 50s, Jayavarman VII came to historical prominence by leading a Khmer army to oust the Cham invaders, which included a naval battle depicted on the walls of Bayon and Banteay Chmar. Returning to the capital, he found it in disorder. He put an end to the disputes between warring factions, and in 1181, he was crowned king.

Aftermath

This event marked the peak of the mandala regime in what is now the South Central Coast of modern Vietnam. Soon after, it was disrupted by the expansionist ambitions of the Thăng Long dynasties, followed by the Mongol invasion of Champa. For the Khmer Empire, heavy losses in the central area forced them to abandon the lower Mekong region, leaving it deserted for several centuries until the Nguyễn lords came to reclaim it. The influence of the Khmer Empire then decreased markedly, causing Cham kings to seek marriage with the Javanese royal families for the sake of protection, and at the same time, the Khmer court also began to receive a large number of Muslim settlers, which helped strengthen the very remote lower Mekong region.Hourani 1995: 70–71GCRC 2006: 24Taouti 1985: 197–198 All of this led to rapid changes in the southern part of the Indochinese peninsula, as Islam became increasingly influential among the aristocracy.Sự khác biệt giữa người Sunni và Shia là gì?Mỗi năm, hàng triệu người hành hương về thánh địa Makkah Alberto Pérez Pereiro (2012).
