12. VAISHNAVISM
These valorous Kalabhra Kings ruled with an upper hand, relentlessly for almost three hundred years from 300 AD to 600AD. The reign of Kalabhras of South India finally came to an end in the 8th Century AD when the Pallavas, Pandyas, Chalukyas and the Rashtrakutas extirpated them from South India.

Most historians think that there was a group of Buddhist or Jain marauders who were anti-Brahminic anti-ritualistic who forcefully occupied the land during this period and whose identity is not known. These people are called Kalabhras. Thus we have the Wikipedia statement:
"Historians speculate that these people followed Buddhist or Jain faiths and were antagonistic towards the Hindu and Brahminical religions adhered by the majority of inhabitants of the Tamil region during the early centuries C.E. As a result Hindu scholars and authors who followed their decline in the 7th and 8th century C.E. may have expunged any mention of them in their texts and generally tended to paint their rule in a negative light. It is perhaps due to this reason, the period of their rule is known as a 'Dark Age' - an "interregnum".
