When Uraiyoor was the capital of the Chola kingdom, many local kings became their supporters and vassals. One of them called Pazhuvettarayar was the king of Pazhuvoor. The name of Periya Pazhuvettarayar was Ambalavaanan and is mentioned in the ASI board displayed outside the Keezha Pazhuvur Temple. Another famous general, Paluvettaraiyar Maravan Kandanar served Uttama Chola. A battle-hardened old warrior and a powerful nobleman, he was Sundara Chozhan's treasurer as well. His son, Kumaran Maravan also served Uttama Chola. Ambalavan Pazhuvurnakkan (also known as Vikramachola - Maharajan of Kuvalalam) features during Uttama Chola's rule and continues into Rajaraja I's reign.
The Pazhuvettaraiyars, related to the Cholas by marriage, were responsible for a number of donations to the Pazhuvur Temples. Inscriptions say that in the 12th year of Parantaka Chozhan, Paluvettaraiyar Kandan Amudanar fought a victorious battle at Vellore against the forces of the Pandya king and his Ceylonese ally, in which the Pandya lost his life.
Keezha Pazhuvur’s Alanduraiyappar Temple finds mention in the hymns of Thevaram sung by Thirugnana Sambandar, the poet-saint of Tamil literature. The hymn says that the temple rituals were conducted by priests from Kerala who settled down in this area. Legend says that Parasurama, the sixth incarnation of Lord Vishnu and creator of the land of Kerala, brought them to conduct the poojas and rituals of Alanduraiyappar Temple. Some scholars say that the Pazhuvettarayars, who belonged to the land of Parasurama, may have encouraged their migration.
