Most of us think that kerala is the chera dhesam. But as per historical records, kerala is referred as kairala dhesam & malayala dhesam..
The boundaries of chera dhesam has been clearly marked in some tamil literatures which dealt with history..
For eg, when we were studying about konga dhesam, we found that it is often referred as chera dhesam.. The boundaries, rivers, and mountains of konga dhesam has been clearly defined..
Dear, You have stated the present kerala is not chera desan. I shall be thankful to you if you kindly intimate the historical reference therefor. It will be immensely helpful for my research work
