Bhargava Rama is a name of Parashurama, the sixth
incarnation of Bhagvan Srihari Vishnu. Bhargava Rama is the name widely used in
Mahabharata. His father was Sage Jamadagni and one his ancestors was Bhrigu
Rishi. So he was known as Bhargava. When he was born his was named Rama. Thus
he came to be known as Bhargava Rama.
It must be noted here that the name Parashuram is not used
in Mahabharata. The sixth incarnation of Vishnu is referred as Bhargava Rama or
Jamadagnya.
Bhargava Rama appeared to annihilate those Kshatriyas (the
warrior class) that had strayed from the path of Dharma and oppressed people
and destroyed Mother Nature.
Exploits of Bhargava Rama are mentioned in Mahabharat,
Ramayana and the Puranas. It is said that this avatar of Vishnu killed 21
generations of Kshatriyas.
