When Dravidanadu was a victim to Aryan deceit, Thirukkural was written by a great Dravidian Thiruvalluvar to free the Dravidians. Periyar E. V. Ramasamy
Aryans made the Dravidians to celebrate the Deepavali festival, Rama's birthday, Krishna's birthday. Similarly the Northerners made the Dravidians celebrate August 15th as the Independence Day. That is all. There is no other benefit or laudable reason. Periyar E. V. Ramasamy
