Yasovarman I () was an Angkorian king who reigned from AD 889-910.

Early Years

After the death of Indravarman I, a succession war was fought by his two sons. It's believed that the war was fought on land and on sea by the Tonle Sap. In the end Yasovarman I prevailed. Because of his father had sought to deny his accession, according to inscriptions cited by L.P. Briggs, "Yasovarman I all but ignored his claim to the throne through his father, Indravarman I, or through Jayavarman II, the founder of Angkor dynasty, and built up an elaborate family tree, connecting himself through his mother with ancient kings of Funan and Chenla.

Yasovarman I's achievements

During the first year of his reign, he built about 100 monasteries (ashrams) throughout his kingdom. Each ashram was used as a resting place for the ascetic and the king during his trips. In 893 he began to construct the Indratataka Baray (reservoir) that was by started by his father. In the middle of this lake (now dry), he built the temple Lolei. Simultaneously, he started to dig a huge reservoir at his new capital (describe below). This new artificial lake, the Yashodharatataka or the Eastern Baray, was eight times bigger than the previous one.

Yasovarman I was one of the great Angkorian kings. His greatest achievement was to move the capital from Hariharalaya to Yashodharapura where it remained there for 500 years. It was at this new capital where all of the great and famous religious monuments were built, e.g. the Angkor Wat. There were many reasons for the move. For one the old capital was crowded with temples built by the previous kings. Thus, the decision was religious: In order for a new king to prosper, he must build his own temple and when he died it must become his mausoleum. Second, the new capital was closer to the Siem Reap River and is halfway between the Kulen hills and the Tonle Sap. By moving the capital closer to the sources of water the king could reap many benefits provided by both rivers. He also constructed a road linking the old capital to the new one.

The Lolei, Phnom Bakheng, and the East Baray reservoir are monuments to this ruler, all located near Cambodia's national treasure, a later construction, Angkor Wat. Phnom Bakheng was one of three hilltop temples created in the Khmer Empire's Angkor capital region during Yasovarman's reign, the other two being Phnom Krom and Phnom Bok.
