The Chola kingdom is referred to in the Sangam literature as Chonadu, Kaveri Nadu, Kaveri Soozh Nadu, Neer Nadu, and Punal Nadu. These names indicate the rich water resources of the Chola country. The river Kaveri has flown through the Chola kingdom and made its soil fertile. The capital of the Sangam Cholas was Uraiyur. Their second capital was Kaveripoompattinam. It was also the chief port of the Sangam Cholas. Their symbol was tiger. The Sangam literature also mentions a number of Chola kings. They had surnames like Kill, Valavan, Senni and Cholan. The kingdom of the Sangam Cholas comprises the present Tanjore and Tiruchirappalli districts.
The most popular among the Sangam Cholas was Karikalan. Both the Sangam works, Pattinappalai and Porunaruatruppadi give information about Karikalan. Even in his young age, he proved his extraordinary ability of settling the disputes in his kingdom. He was also a great warrior. He defeated the Chera and Pandya kings at Venni. In another battle Karikalan defeated a confederacy of nine princes. He extended his kingdom beyond Kanchipuram in the North.
