The Cham controlled Angkor for four years until the legendary Jayavarman VII mounted a series of counter attacks over a period of years. He drove the Cham from Cambodia in 1181. After the Cham defeat, Jayavarman VII was declared king. He broke with almost 400 years of tradition and made Mahayana Buddhism the state religion, and immediately began Angkor’s most prolific period of monument building.
Jayavarman VII’s building campaign was unprecedented and took place at a frenetic pace. Hundreds of monuments were constructed in less than a 40-year period. Jayavarman VII’s works included Bayon with its famous giant faces, his capital city of Angkor Thom, the temples of Ta Prohm, Banteay Kdei and Preah Khan, and hundreds of others. The monuments of this period, though myriad and grand, are often architecturally confused and artistically inferior to earlier periods, seemingly due in part to the haste with which they were rendered.
After a couple of days at the temples, you should begin to recognize the distinctive Bayon-style of Jayavarman VII’s monuments. Note the giant stone faces, the cruder carving techniques, simpler lintel carvings with little or no flourish, the Buddhist themes to the carvings and the accompanying vandalism of the Buddhas that occurred in a later period.
At the same time as his building campaign, Jayavarman VII also led an aggressive military struggle against Champa. In 1190 he captured the Cham king and brought him to Angkor. In 1203 he annexed all of Champa, thereby expanding the Khmer Empire to the eastern shores of southern Vietnam. Through other military adventures he extended the borders of the empire in all directions.
Jayavarman VII’s prodigious building campaign also represents the finale of the Khmer empire as no further grand monuments were constructed after his death in 1220. Construction on some monuments, notably Bayon, stopped short of completion, probably coinciding with Jayavarman VII’s death. His successor, Indravarman II continued construction on some Jayavarman VII monuments with limited success.
