A revolt occurred among the polygars, during his reign, but its leader Thumbichi Naidu (Dumbicchi Nayakkan) was captured and the trouble was quenched. In 1565 the Sultan rulers of the Deccan defeated Vijayanagara, the suzerain of the Nayaks, at the battle of Talikota. Vijayanagara had to abandon their capital Vijayanagara and take reestablish at Penukonda in Anantapur, then at re-establish at Vellore Fort and Chandragiri near Tirupathi, which later granted land to the British East India Company to build a fort at the present day Chennai. Finally they settled at Vellore in North Arcot. Their governors at Madurai, Kalahasti, Gingee and Tanjore still paid them tribute and other marks of respect; but in later years, when their suzerainty became weak, the Nayaks ruled independently. Kumara Krishnappa Nayak was succeeded in 1573 by his two sons, who ruled jointly and uneventfully until 1595, when they in turn were succeeded by their two sons, one of whom ruled until 1602. These were followed by Muttu Krishnappa Nayak. He is credited with having given the Setupatis of Ramnad a considerable slice of territory in the Maravar country, on condition that they suppress crime and protect pilgrims journeying to Rameswaram. These were the beginnings of Ramnad kingdom. Muttu Krishnappa Nayak was succeeded by his eldest son, Muttu Virappa. He began the construction of the Dindigul Fort at Dindigul on the Hill, along with the Temple on it, which later was completed by Tirumalai Nayak. Muttu Virappa's rule was in general not noteworthy and he is said to have allowed his favourites to tyrannise the people unchecked. Muttu Virappa is said to have had several vassals under him indicating that he must have already obtained great power; and he is stated to have paid the Vijayanagara king at Chandragiri a tribute of 600,000 pagodas in 1616. During Muthu Virappa's rule, a civil war involving succession to the throne was taking place in the Vijayanagara Kingdom, now based in Vellore and Chandragiri. Gobburi Jagga Raya, brother of the previous ruler Venkata II's favourite queen Bayamma claimed her putative son as the king and murdered Sriranga II along with his family in the Vellore prison.
