I have a question. The so-called 'Keralaanthagan' - who was defeated by Rajaraja Cholan - was he a Chera King? The entire Kerala of those days belonged to Chera right? or was there a small portion of the region that belonged to a different kingdom which wasnt of Chola, Chera or Pandya mixture?
Yesterday there was an argument with my collegue who said that 'Kerala was not invaded by any north indian invasion'. I said that 'Yes,but the entire south India was under the control of the Moovendhars and Kerala was nothing but Chera Nadu. That's why nobody could enter. But he said that some part of Kerala was a seperate kingdom.
Keralanthahan divides into Kerala + Anthahan. Anthaham is a Sanskrit word meaning "the end" or "finish". Kerala Anthahan means the one who has "put an end" or "finished" (i.e.captured)the Keralam. This was a title of Rajaraja Chola - 1 (A.D.984-1014)which he bore after his capture of Kerala. He has named a Brahmin Settlement as Keralanthaha Chathurvedi Mangalam. He has named one of the main entrance to Thanjavur Rajarajaeswarem as Kerlanthaka Vaayil, etc.
The capture of Kandalur Salai or Vilignam or Kollam never meant that he captured the Kerala. It was his capture of Kudamalai Nadu with its capital at Mahodai the present Kodungallur, which meant he captured the Kerala. The regions of Kollam, Vilignam, Kandalur Salai all were under different subordinate kings of Kerala who accepted the authority of the Kerala King at Mahodai of this period.
Refer to my Thread titled "The medieval Chola Empire and their relations with Kerala" - in WWW.mayyam.com I think this same article I posted around A.D.2004 in this PS Forum. Please check.
Also await my new research article titled "The great significance of Kodungallur of Kerala in the history of Kerala and Tamil Nadu", to be posted both in PS Forum and in mayyam.com.
