MUTHARAIYAR KINGDOM OF KAVERI BASIN
The found inscript from Tiruvannamalai district Thandrampattu and Balawadi, Kulathuer inscripts in Dharmapuri districts clearly enlighten us about the establishment of the great kingdom in Kaveri river belt before the kingdom was established by Kuvavan Sathan as quaoted by Sendalai inscripts according to Nandana Kasinathan, the history researcher. The Pon Mandharaiyar and Vanako Mutharaiyar ruled Thondai Mandalam. Not only Thondaimandalam, their heaquarter was Meir Kovalur in the period 630 – 637 AD. His successor was Vanako Mutharaiyar and followed y Perumbana Mutharaiyar 642-664 AD, the sub-rulers of Kadaladi, Meil Ponsei. The Thondai Mutharaiyars also brought Konkan, and Ganga rulers under their supervision. Thondai Mutharaiyras kingdom was extended upto the end of Northern Tamilnadu in South India upto Mysore. So it shows that Mutharaiyars are the base history for Tamilnadu history .Mutharaiyars are unshakable kings anf the kingdom in Kavery ,Cheyiar and Pallar river belt for about 150 years.
