The kshatriyas were the second of the four classes. It was their job to wear arms and protect the world. And rule. The brahmanas were the first of the four classes. It was their job to pray, study the sacred texts and perform religious rites. But the kshatriyas became very insolent and began to oppress the world and the brahmanas. Vishnu was then born as the son of the sage Jamadagni and his wife Renuka. Since this was the line of the sage Bhrigu, Parashurama was also called Bhargava. Parashurama’s mission was to protect the brahmanas and teach a lesson to the kshatriyas.
There was a king named Kartavirya who had received all sorts of boons from the sage Dattatreya. Thanks to these boons, Kartavirya had a thousand arms and conquered and ruled over the entire world. One day, Kartavirya went on a hunt to the forest. He was very tired after the hunt and was invited by the sage Jamadagni had a Kamadhenu cow. This meant that the cow produced whatever its owner desired. Jamadagni used the Kamadhenu to treat Kartavirya and all his soldiers to a sumptuous feast.
Kartavirya was so enamoured of the Kamadhenu that he asked the sage to give it to him. But Jamadagni refused. Kartavirya then abducted the cow by force and a war started between Kartavirya and Parashurama. In this war, Parashurama cut off Kartavirya’s head with his axe (parashu) and brought the Kamadhenu back to the hermitage.
After some time, Parashurama was away when Kartavirya’s sons arrived at the ashrama and killed Jamadagni. On the death of his father, Parashurama’s anger was aroused. He killed all the kshatriyas in the world twenty-one times. On the plains of Kurukshetra, he built five wells which were filled with the blood of kshatriyas. Eventually, Parashurama handed over the world to Kashyapa and went and lived on Mount Mahendra.
