Salimgarh Fort under Sur Dynasty
In 1540AD, Sher Shah Suri defeated Humayun and established Sur Dynasty that ruled till 1555AD. Sher Shah Suri was succeeded by Islam Shah Suri who built the Salimgarh Fort in an area where there was Yamuna river on one side and range of Aravalli hills on the other side. This was done in order to save the fort from erosion done by the river. In spite of all these protections, Humayun invaded the fort and defeated Sikandar Suri, the last ruler of Sur dynasty.
