Bhargava is a common surname in Northern India and Maharashtra, mainly around Nashik. In Maharashtra, it is pronounced as Bhargave instead of Bhargava. It is also used as a first name in parts of southern India.

Bhargavas owe their lineage to Bhrugu Rishi, and his son Chavan Rishi, who is better known for creating Chyawanprash. According to Hindu Scriptures, Bhargava or Parashurama as he is better known was a threat to the Kshatriya Kings who ruled in India during Treta and Dwapara Yuga. The arrival of this warrior class sage to India was somewhere around the transition period of Treta Yuga and Dwapara Yuga.

They have attacked and annihilated the existing Kshatriya rulers of India, as many as 21 times, probably spanning a time period of a 1,000 years. The rulers of central India were the major victims of this massacre. The first victim of Parasurama was a ruler of central India, of Haiheya tribe, called Kartavirya Arjuna. Bhargava and Kshatriya were hostile to each other for this many years until they started living in harmony.
