The beautiful Tulunadu which we see today was not the part of land. Way back it was the part of the ocean. It was Parashurama, who is said to be the sixth Avatara of Lord Vishnu according to Hindu who made it a part of the land.
Parashurama was a Brahmin and was the son of sage Jamadagni and his wife Renuka. Once, Jamadagni ordered Parashurama to chop the head of his mother because he was angry on her. Parashurama being the follower of father's words, chopped his mother's head with his axe. Later when his father agreed to give him blessings, he asked Jamadagni to revive his mother. Jamadagni agreed and his wife came alive by his blessings. This is the early story of Parashurama.
Parashurama hated all the Kshatriyas so, he destroyed them all and donated the gained land to sage Kashyapa. After donating all the land, he thought, staying in the donated land is not right. So, he went on to Sahyadri to meditate and seek blesdings of devine Lord Shiva. Shiva appeared before him and said, he would incarnate in Kadri which was then called Kadalivana and asked Parashurama to meditate there. When Parashurama came to Kadalivana, it was occupied by the ocean. So, Parashurama went to the Ocean King and asked him to take back the ocean from that part of the land. When the ocean king refused to do so, Parashurama threw his axe to an extent in anger. By the fear of Parashurama's anger, the ocean king took back the ocean from the place where the axe fell and this how Tulunadu was formed. So, Tulunadu is also called as The Parashurama Srishti or Parashurama Kshetra.
