The Vijayanagara rulers in the course of a series of campaigns succeeded in overthrowing the Muslims, and they held the title Mahamandaleswar and ruled the whole of South India. It was at this time that the Ummattur chieftains were apparently governing the dominion of Vijayanagara in Karnataka and Kongu region. The Umattur chieftains seem to have ruled over the Kongu country from 1446 to 1520 CE more or less peacefully rebuilding ruined temples and rehabilitating ruined towns damaged during the Muslim rule. Their rule ended when Krishnadeva Raya (1509 CE–1529 CE) of Tuluva dynasty ascended to power. The first record comes from Kokkarayapet (Salem district) which describes him as Rajakkal Tambiranar. In the 1550s, Madurai Nayaks, who were the military governors of the Vijayanagara Empire, took control of the region. British India Period
