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.

It is very different from the other forts in state, there is no flamboyance associated to fort but it generates an aura of strength and magnificence. The fort is surrounded with moat which was previously filled with water to ward off the enemy attacks. The sandy ramparts were strengthened by sandy battlements, thus the enemy guns proved of no avail.Some interesting monuments in the fort are Kishori Mahal, Mahal Khas and Kothi Khas. Moti Mahal and towers like Jawahar Burj and Fateh Burj were erected to commemorate the victory over the Mughals and the British army . The Gateway has paintings of huge elephants.
