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.^[24] His rule was marked by repeated attempts by his opponents to overthrow him and military conflicts with neighbouring kingdoms.^[26] Suryavarman I established diplomatic relations with the Chola dynasty of south India early in his rule.^[27] In the first decade of the 11th century, Kambuja came into conflict with the kingdom of Tambralinga in the Malay peninsula.^[26] After surviving several invasions from his enemies, Suryavarman requested aid from the powerful Chola emperor Rajendra I against Tambralinga.^[26] After learning of Suryavarman's alliance with Chola, Tambralinga requested aid from the Srivijaya king Sangrama Vijayatungavarman.^[26] 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.^[26] 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.^[24]
