History of Kerala

According to the legends, Lord Parasurama created the land between Gokarna and Kanyakumari. Lord Parasurama the sixth incarnation of Lord Vishnu was the son of Sage Jamadagni and Renuka. As a mark of repentance for Kshatriya Nigraha sin, Parasurama meditated at Gokarna and invoked Lord Varuna (the Lord of the Oceans). Parasurama asked him for a boon. To absolve himself of the sins he had committed, he wanted to donate some land to the Brahmins. There was no land available because he already donated the whole land he obtained by the 21 round Kshatriya Nigraha to Sage Kashyapa. Lord Varuna told Parasurama that he would give him as much land as he wished. He told him to fling his Parasu (axe) from where he stood at Gokarna. The land from Gokarna till the point where the axe landed would be given to him was the boon that Lord Varuna promised him. The throw of the `axe' from Gokarna to Kanyakumari created Kerala. Parasurama donated this land to the Brahmins and settled Brahmins there in 64 gramams or villages.
32 out of the 64 gramams are in the Tulu speaking region (in between Gokarnam and Perumpuzha) and the remaining 32 gramams are in the Malayalam speaking region(in between Perumpuzha and Kanyakumari) in Kerala.
