Barmer was a beehive of activity till a few centuries ago, and a number of important kingdoms flourished at various times in the district during the medieval age. The chief principalities of Barmer at the time were Khed, Kiradu, Pachpadra, Jasol, Tilwara, Sheo, Balotara and Mallani. It was the Panwara clan which had strong links with the Solanki dynasty of Gujarat, whose sphere of influence extended right across the Barmer region at the time. Later they wrested Mandore, which was the former capital of Jodhpur and held it for a while. Meanwhile, Khed and Mallani districts were captured by the Guhil Rajputs who were ruling over Mewar at the time.
In 1212AD Rao Siha, founder of the Rathore clan, conquered Khed in Barmer district and planted the Rathore flag in the area. The region was regained by the Guhil Rajput Pratap Singh, but was later reclaimed by the Rathore Rao Asthan. Not much is known about the history of Barmer for a while after that until a ruler Tribhuvansi ascended the throne, which led to fratricidal feud with his cousin Mallinath. The ambitious Mallinath (after whom the town of Mallani was later named) sought the assistance of the Sultanate ruling at Delhi at the time and defeated Tribhuvansi’s army in 1374
