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.
