After the death of Khizar khan, his son Mubarak Shah ascended the throne of Delhi. He ruled for about twelve years, from 1421 to 1433. All his life was spent in curbing one revolt or the other. Otherwise his rule was uneventful as was that of his father. He repudiated allegiance to Shah Rukh, Mubarak Shah fortified Lahore but being inferior to his father as a soldier and statesman he was not wholly successful as a ruler. On his way to Kalpi, Mubarak Shah was assassinated in 1434. As he had no son, Muhammad bin Faud , a nephew of his was enthroned by the nobles.
