However, most reports suggest that Bhangarh was established in 1573 by King Bhagwant Das. He had two sons, the elder son, Man Singh, was the famous General of the great Mughal Emperor, Akbar, and the younger one was Madho Singh. The fort was likely established by Bhagwant Das for his younger son, Madho Singh, who spent his entire life in Bhangarh.
