Tamilakam in the Sangam age

Sangam poetry (the Purananuru, Akananuru, Ten Idylls and Patirruppattu) describes a Tamil country running from the Venkatam hills to Cape Kumari. It was shared by three 'crowned kings' and a ring of Velir chiefs in the hills between them. The Cholas held the Kaveri delta, the Pandyas the Vaigai and Tamirabarani basins, and the Cheras the Malabar coast and later Kongu. Ashoka's edicts, the Hathigumpha inscription, the Periplus, Pliny, Ptolemy, Tamil-Brahmi inscriptions and digs at Keezhadi, Kodumanal, Arikamedu and Pattanam confirm the kingdoms, capitals and ports. No source draws a frontier, though. The changes over time follow Nilakanta Sastri's dating, which puts most named kings in c. 100–250 CE. Other scholars place them a century or more earlier.
