Jayavarman VII

Following the death of Suryavarman around 1150 A.D., the kingdom fell into a period of internal strife. Its neighbors to the east, the Chamof what is now southern Vietnam, took advantage of the situation in 1177 to launch a seaborne invasion up the Mekong River and acrossTonle Sap. The Cham forces were successful in sacking the Khmer capital of Yasodharapura and in killing the reigning king. However, a Khmer prince who was to become King Jayavarman VII rallied his people and defeated the Cham in battles on the lake and on the land. In 1181, Jayavarman assumed the throne. He was to be the greatest of the Angkorian kings. Over the ruins of Yasodharapura, Jayavarman constructed the walled city of Angkor Thom, as well as its geographic and spiritual center, the temple known as the Bayon. Bas-reliefs at the Bayon depict not only the king's battles with the Cham, but also scenes from the life of Khmer villagers and courtiers. In addition, Jayavarman constructed the well-known temples of Ta Prohm and Preah Khan, dedicating them to his parents. This massive program of construction coincided with a transition in the state religion from Hinduism to Mahayana Buddhism, since Jayavarman himself had adopted the latter as his personal faith. During Jayavarman's reign, Hindu temples were altered to display images of the Buddha, and Angkor Wat briefly became a Buddhist shrine. Following his death, a Hindu revival included a large-scale campaign of desecrating Buddhist images, until Theravada Buddhism became established as the land's dominant religion from the 14th century.
