Ala ud din Masud Shah was a ruler of the Delhi Sultanate who reigned from 1242 to 1246 CE during the period of the Mamluk, or Slave, dynasty. He was a grandson of Iltutmish and came to the throne after the deposition of Bahram Shah. Masud Shah’s reign was marked by political instability and the growing power of Turkish nobles, who dominated the government and weakened the authority of the sultan. Although initially popular, he struggled to control factional disputes within the court and failed to establish strong central rule. In 1246 he was deposed by the nobles and replaced by his uncle Nasiruddin Mahmud, after which Masud was likely imprisoned and later killed.
