The history of Bharatpur dates back to the epic age, when the Matsya Kingdom flourished here in the 5th century BC. The Matsyas were allies of the Pandavas in the Mahabharata war. According to tradition the name of Bharatpur is traced to Bharat, the brother of Lord Rama of Ayodhya whose other brother Laxman was given the highest place of family deity of the ruling family of Bharatpur. His name also appears in the state seals and coat-of-arms. Bharatpur is also called the Eastern gateway of Rajasthan. Maharaja Suraj Mal apart from being a brave General was also a great builder. He built numerous forts and palaces across the kingdom including the Pleasure Palace complex at Deeg. Bharatpur is today known the world over for its Keoladeo Ghana National Park.
