Explanation:
? One important event in the 6th century is a revolt led by the Kalabhras. The Kalabhras seem to have been the tribal people who captured power, particularly at the cost of the Cholas, and ruled for seventy-five years. Their rule also affected the Pallavas, as well as their neighbouring contemporaries. The Kalabhras are called evil rulers, who overthrew innumerable kings and established their hold on the Tamil land. The Kalabhra revolt was a powerful peasant protest directed against the landed Brahmanas. The repeated teaching that those who attack land grants are condemned to hell for sixty thousand years failed to change their minds. They put an end to the Brahmadeya rights granted to the
Brahmanas in numerous villages. 
? It appears that the Kalabhras were of Buddhist persuasion, as they patronized Buddhist monasteries. The Kalabhras’ revolt was so widespread that it could be quelled only through the joint efforts of the Pandyas, the Pallavas and the Chalukyas of Badami. By the last quarter of the sixth century, according to a tradition, the Kalabhras had imprisoned the Chola, the Pandya and the Chera kings, which underlines how formidable their revolt was. The confederacy of the kings formed against the Kalabhras, who had revoked the
land grants made to the Brahmanas, shows that the revolt was directed against the existing social and political order in south India.
