'Sangam' refers to a group of poets who were under the patronage of the kings of the Pandya Dynasty. The Sangam Age refers to the period of history when these poets composed poets about Tamilagam (ancient Tamil Nadu). It extended from Vengadam (Tirupathi hill) in the north to Kanyakumari (Cape Comorin) in the south, bounded by sea on the east and the west. It comprised of modern day Kerala, Tamil Nadu, Puducherry, Lakshadweep, and southern parts of Andhra Pradesh and Karnataka.
