Mauryan Incursions of Tamil Nadu – There are a few Sangam songs that describe the Mauryan incursions into Tamil Nadu. The Mauryas had conquered the rest of India, but did not conquer Tamil Nadu. They made incursions into the northern parts of Tamil Nadu. Akam 281 below reveals that the Vadukars (Telugu speaking) helped the invading Mauryas.
The Mauryas ruled from 321 to 185 B.C. These poems obviously belong to that period.
