The place was named as Bharatpur after the name of Bharat, the brother of Lord Rama, whose other brother Laxman was worshipped as the family deity of the Bharatpur. The legends say the rulers Laxman's name is engraved on the state arms and the seals. The city and the fort have been believed to be founded by Rustam, a Jat of Sogariya clan. Maharaja Suraj Mal took over from Khemkaran, the son of Rustam, and established the empire. He fortified the city by building a massive wall around the city.

The interesting aspect of the Bharatpur history is the domination of Jats in the region since 17th century. Leaders like Churaman and Badan Singh brought the jats together to mould them into a force to reckon with. Suraj Mal has been the greatest ruler who made them a formidable force and played a very important role in the Indian history during 19th century.
