Khmer Empire
Establishment of Yasodharapura

Indravarman I was followed by his son Yasovarman I (reigned 889–915), who established a new capital, Yasodharapura – the first city of the larger Angkor area. The city's central temple was built on Phnom Bakheng, a hill which rises around 60 m above the plain on which Angkor sits. The East Baray, a massive water reservoir measuring 7.1 by 1.7 kilometres (4.4 by 1.1 mi), was also created under the reign of Yasovarman I.

At the beginning of the 10th century, the empire fractured. Jayavarman IV moved the capital to Lingapura (now known as Koh Ker), some 100 kilometres (62 mi) northeast of Angkor. Only when Rajendravarman II ascended to the throne (reigned 944–968) was the royal palace returned to Yasodharapura. He once again took up the extensive building schemes of the earlier kings and established a series of Hindu temples in the Angkor area, such as Pre Rup and the East Mebon, a temple located on an artificial island in the center of the East Baray. Several Buddhist temples and monasteries were also built. In 950, the first war took place between Kambuja and the kingdom of Champa to the east (in what is now central Vietnam).

The son of Rajendravarman II, Jayavarman V, reigned from 968 to 1001, after establishing himself as the new king over the other princes. His rule was a largely peaceful period, marked by prosperity and a cultural flowering. He established a new capital slightly west of his father's and named it Jayendranagari; its state temple, Ta Keo, was to the south. At the court of Jayavarman V lived philosophers, scholars, and artists. New temples were also established; the most important of these were Banteay Srei, considered one of the most beautiful and artistic of Angkor, and Ta Keo, the first temple of Angkor built completely of sandstone.

A decade of conflict followed the death of Jayavarman V. Three kings reigned simultaneously as antagonists to each other until Suryavarman I (reigned 1006–1050) ascended to the throne by taking the capital Angkor. His rule was marked by repeated attempts by his opponents to overthrow him and military conflicts with neighbouring kingdoms. Suryavarman I established diplomatic relations with the Chola dynasty of south India early in his rule.

In the first decade of the 11th century, Kambuja came into conflict with the kingdom of Tambralinga in the Malay peninsula. After surviving several invasions from his enemies, Suryavarman requested aid from the powerful Chola emperor Rajendra I against Tambralinga. After learning of Suryavarman's alliance with Chola, Tambralinga requested aid from the Srivijaya king Sangrama Vijayatungavarman. This eventually led to Chola coming into conflict with Srivijaya. The war ended with a victory for Chola and Kambuja, and major losses for Srivijaya and Tambralinga. The two alliances had religious nuance, as Chola and Kambuja were Hindu Shaivite, while Tambralinga and Srivijaya were Mahayana Buddhist. There is some indication that, before or after the war, Suryavarman I gifted a chariot to Rajendra I to possibly facilitate trade or an alliance.

Suryavarman I's wife was Viralakshmi, and following his death in 1050, he was succeeded by Udayadityavarman II, who built the Baphuon and West Baray. In 1074, conflict arose between Harshavarman III, the younger brother and successor of Udayadityavarman II, and the Champa king Harivarman IV.
