9th century CE), one of the twelve Vaishnavite alvars, was a bhakti theologian and devotional poet from medieval south India.

[8] When the prince came of age, his father abdicated the kingdom and retired from public life, and the new king Kulasekhara ascended the throne.

His piety was so great that on one occasion when the story was being narrated as to how demon king Ravana abducted princess Sita, he at once issued orders to marshal out his army for the invasion of Lanka.

In another instance, a minister who felt jealous of the favor showered by the king on Vaishnavites, trumped up on the devotees a false charge.

[8] He also gave away his whole wealth as dowry, built the Chenaivenran Mandapa and repaired the prakara of the temple (which was thereafter called "Kulasekhara Tiruvidi").

[8] He then visited the holy temples of Tiruvenkatam, Tiruvayodhya, Tillai-Chitrakutam, Tirukannapuram, Tirumalirunjolai and Tiruvitruvakkode and finally settled down at Brahmadesam near Tirukkurukur, the birthplace of Namma Alvar (where he died at the age of sixty seven).

[3] Kulasekhara Alvar's poems are devotional in nature, being dedicated to the most prominent avataras of god Vishnu - Rama and Krishna.
