Bhargava is another name for Parashurama, one of the 10 incarnations of Lord Vishnu. He is the son of Sage Jamadagni & Renuka. He was a manifestation of the ultimate divinity's need to balance 'dharma' and 'adharma' (harmony and disharmony) and consequently visited justice on many kings who had been abusing their power or had lost a hold on their ethics as protectors of their dominions. His time of activity comes to a close when he encounters Lord Rama (another of the avatars of Lord Vishnu).
