N.K. Sastri claims that this is the period where Maurya dynasty had established its empire from Persia to southern India. Bindusara, son of Chandragupta Maurya, conquered almost the whole of India except Kalinga and Cholas. But fragmentary poems of Sangam in the Purananuru[2] states that, Ilamchetcenni Cholan successfully resisted[3] the exploration of Mauryas down the southern region of the Indian subcontinent. Also Sastri claims that his period of reign is 301 BCE – 270 BCE and Cholas overpowered Cheras and Pandyas at time of his regin.[4]
