- Ikhtkiyar al-Din Daulat Shah
- After the death of Nasir al-Din Mahmud (son of Iltutmish) at Lakhnauti in 1228, the authority there was usurped by Daulat Shah (also known as Bilge Malik), who was formerly an official deputed from Delhi. He declared himself a sovereign ruler of the province. Some of the coins struck by him from Lakhnauti have survived.
