Also on a parallel note, in the earliest historical period, the area now known as the Carnatic was divided between the Pandya and Chola kingdoms, which with that of Chera dynasty or Kerala formed the three Tamil kingdoms of southern India. The Pandya kingdom practically coincided in extent with the districts of Madura and Tinnevelly; that of the Cholas extended along the Coromandel coast from Nellore to Pudukottai, being bounded on the north by the Pennar River (Penner River) and on the south by the Southern Vellaru.
