The Ranokot fort is believed to be associated with the Dharaja state, one of many fiefdoms within the deltaic region that existed during the decline of the Mughal Empire in the 18th century. While the Mughal governorship was based in Thatta and supported by the Kalhoras, the Ranas of Dharaja ruled the western delta region. Ranokot was one of their primary strongholds. The fort is located in an agricultural area of Mirpur Sakro. While historically it helped protect the adjacent waterways, it now lies over a mile away from the closest river creek.
