Nilakanta Sastri and Elamkulam P. N. Kunjan Pillai are employed. In 1005 AD, i. e., 20 regnal year of emperor Rajaraja I (985–1014 AD), there is a reference (in the Senur inscription) to the defeat of the "haughty" kings at Kollam, Kolladesam and Kodungallur at the hand of Rajaraja. The Kolladesam is identified with the Mushika kingdom in north Kerala. According to scholars, "plunder is emphasised more than conquest [in the inscription] and it is likely that the victories at Kollam in the south, Kodungallur in the center and Kolladesam in the north of Kerala have been primarily the achievement of [the Chola] naval forces". Chola emperor Rajadhiraja (1019–1044–1053/4 AD) is stated to have "confined the undaunted king of Venatu [back] to Che[ra]natu, destroyed the Iramakuta Muvar in anger, and put on a fresh garland of Vanchi flowers after capturing Kantalur Salai [Vizhinjam?] while the strong Villavan [the Chera/Perumal king] hid himself in terror inside the jungle". The Irumakuta Muvar is not named in the above Chola prasasti'' (the above events are dated to around 1018–19 AD). The presence of Chola army in north Kerala (1020 AD) is confirmed by the Eramam inscription of Chera/Perumal Bhaskara Ravi Manukuladitya (962–1021 AD) (which mentions a meeting attended by Rajendra Chola Samaya Senapati in the Chalappuram Temple).
