N.K. Sastri claims that this is the period when the Maurya dynasty established its empire from Persia to southern India. Bindusara, son of Chandragupta Maurya, conquered much of India besides Kalinga and the Cholas. Fragmentary Sangam poems in the Purananuru state that Ilamchetchenni Cholan successfully resisted unknown Aryan army with chariots invasion in the southern region of the Indian subcontinent. Sastri claims that Ilamchetchenni reigned from 501 BCE to 470 BCE, when the Cholas dominated the Chera and Pandya dynasties.
