Dadrewa
Dadrewa was a Chauhan Rajput chiefdom in the dry Jangal Desh of north-eastern Rajasthan. In 1337 it was ruled by Motay Rao Chauhan.
His son Karamchand embraced Islam at Sultan Firuz Shah Tughluq’s court around 1352 and took the name Qaim Khan. He became governor of Hisar Firoza, but Khizr Khan trapped and killed him on the Yamuna in 1419. His son Taj Khan governed Hisar from 1420 to 1446. The Qaimkhanis later ruled Shekhawati towns including Fatehpur and Jhunjhunu until their line ended in 1731.
