Explanation:

Sangam literature is one of the main sources of information about the life, culture, and society in ancient Tamilakam (ancient Tamil country). These texts do reference various aspects of material culture, including the warrior ethic, and they portray a vivid picture of the socio-economic and cultural life of the people living in the southern part of India during that period.

Sangam literature does have references to different classes and occupations, suggesting that some form of social classification, possibly analogous to the Varna system of the north, was known to Sangam poets.
