There are a number of poems in Purananuru sung in praise of the Killivalavan who died at Kulamuttram and a solitary poem of another Killivalavan who died at Kurappalli. As Kovur Kilar is the poet who has written about these two Killis, it is reasonable to suppose that these two kings are identical.
SriRangam Temple
The Vimana of Srirangam temple originally came out of "parkadal" with the powers of Brahma Deva. The Incarnation of lord Vishnu called Ramavathara has performed poojas to this Vimana. But as a symbol of love he gave this vimana to vibishana. With a condition, to not to keep that on earth. While He took this Vimana and was traveling towards Sri Lanka, Lord Vinayaka played a trick and made that to stick on the region now called Srirangam, on the banks of River Cauvery. Then Chola kings namely Dharmavarcholan and KilliValavan developed the shrine into Big Temple seen now. They have laid the basic foundations and primary buildings of the great Temple.
Killivalavan’s Reign
Killivalavan is celebrated in eighteen songs by ten different minstrels and himself figures as the author of a poem sung in praise of his friend Pannan who was the chieftain of Sirukudi. Urayur was the capital of Killivalavan. Killivalavan was a capable king and was both brave and generous, but somewhat headstrong. A great deal of good advice was very tactfully offered to him by the poets.
The siege and capture of the Chera capital Karur was the standout military achievement of Killivalavan’s reign and has been the subject of a number of poems. The poet Alattur Kilar made an effort to divert Killivalavan’s attention from this enterprise in order to save Karur from destruction by gently chiding him for pitting himself against an enemy unworthy of his prowess. However this effort was futile and the city of karur fell to the Chola.
Defeat against Pandya
poems are silent on Killivalavan’s campaigns in the south against the Pandyas, but the poet Nakkirar in a poem in Akananuru makes reference to the defeat suffered by the forces of Killivalavan in the hands of the Pandya commander Palayan Maran.
Malainadu Battle
Killivalavan also waged a battle against the Malainadu chief Malayaman Tirumudikkari, who was famous for his liberal patronage of poets. The Malayaman chief was killed in battle and his two children were about to be condemned to a cruel death by the victorious Chola. The poet Kovur Kilar again pleaded for the lives of these children
