Q. Who was the Ujjainiya chief who accepted the suzerainty of Jaunpur Sultanate in the late 1400s?
Answer: Durlabh Deva
Notes: Durlabh Deva, chief of the Ujjainiya Rajputs in Bihar, accepted the suzerainty of the Jaunpur Sultanate in the late 1400s, agreeing to pay regular tribute. This marked the end of protracted conflicts, until Jaunpur itself was merged into the Lodi dynasty in Delhi.
