Bhargava Rama, the son of sage Jamadagni and Renuka was popularly known as Parashurama. Maha Vishnu took the avatara of Parashurama in the early treta yuga when most of bhuloka was being ruled by corrupt and evil kings.

Bhargava learnt the art of warfare and martial arts from Shiva, whom he pleased with extensive penance. Shiva bestowed a divine axe to him, which made him popular as Parashurama. Parashu being axe in samskrita.

Parashurama used the ruse of Kartaviryarjuna killing his father (Sage Jamadagni) to rid the world of the evil kings. He went around the world 21 times, killng all such kings. After the world was cleansed of the evil kings, he went to the western coast of Bharatavarsha and sought some land from the sagara (now known as konkan) to do his penance.
