There are references to the Mahabharata in the Tamil Sangam Literature and The Mahabharata refers to the Tamil Kings.
The Tamil King Perunchotru Udiyan Neduncheralathan was the one who fed both Kauravas and Pandavas during the Mahabharata War.
Arjuna and Sahadeva went on a Pilgrimage to the Tamil Kingdoms in the South.
The Kings of Chola and Pandya, brought numberless jars of gold filled with fragrant sandal juice from the hills of Malaya, and loads of sandal and aloe wood from the Dardduras hills, and many gems of great brilliancy and fine cloths inlaid with gold. Singhalas gave those best of sea-born gems called the lapis lazuli, and heaps of pearls also, and hundreds of coverlets for elephants (2:51).
Bhishmaka, the mighty king of the Bhojas (of Vidarbha Kingdom) who governs a fourth part of the world, by his learning conquered the Pandyas and the Kratha-Kausikas (2:14).
Having met with Rukmi (of Vidarbha Kingdom), Karna, repaired to Pandya and the mountain, Sri. And by fighting, he made Karala Kerala?), king Nila, Venudari’s son, and other best of kings living in the southern direction pay tribute (3:252)
And next turning his forces against the Paurava kingdom, he vanquished and reduced to subjection the monarch thereof. And the prince, after this, with great efforts brought Akriti, the king of Saurashtra and preceptor of the Kausikas under his sway.
The Kuru warrior then vanquished and brought under his subjection numberless kings of the Mlechchha tribe living on the sea coast, and the Nishadas and the cannibals and even the Karnapravarnas, and those tribes also called the Kalamukhas (dark faced) who were a cross between human beings and Rakshasas, and the whole of the Cole (Chola or Kolwa) mountains, and also Surabhi-patna, and the island called the Copper island, and the mountain called Ramaka.
He having brought under subjection king Timingila, conquered a wild tribe known by the name of the Kerakas.
The son of Pandu also conquered the town of Sanjayanti and the country of the Pashandas and the Karanatakas by means of his messengers alone, and made all of them pay tributes to him.
The hero brought under his subjection and exacted tributes from the Paundrayas (Pandyas?) and the Dravidas along with theUdrakeralas and the Andhras and the Talavanas, the Kalingas and the Ushtrakarnikas, and also the delightful city of Atavi and that of the Yavanas.
The mighty Sarangadhwaja, the king of the Pandyas, has white steeds, decked with armour set with stones of lapis lazuli.
His country was invaded and his father was slain by Krishna in battle. Obtaining weapons then from Bhishma and Drona, Bala Rama and Kripa, prince Sarangadhwaja became, in weapons, the equal of Rukmi and Karna and Arjuna and Achyuta.
He then desired to destroy the city of Dwaraka and subjugate the whole world.
Wise friends, however, from desire of doing him good, counselled him against that course.
Giving up all thoughts of revenge, he is now ruling his own dominions. Steeds that were all of the hue of the Atrusa flower bore a hundred and forty thousand principle car-warriors that followed that Sarangadhwaja, the king of the Pandyas, opposing Drona in Kurukshetra War.(7:23).
It is not clear if Pandyas had any tribal links with the Pandavas of north-India.
Their capital was Madhura on the banks of the Vaigai river.
The name Madhura resembles the Mathura of northern India indicative of a connection with the Yadavas who once ruled at Mathura.
By looking at the descriptions of the land of Tamils, especially of Pandyas, one is made to conclude that this land mass was in the submerged continent of Lemuria.
