Alauddin Masood Shah bin Rukhuddin Firuz Shah bin Shamsuddin Iltumish (Persian: علاء الدین مسعود شاه; died 10 June 1246) was the seventh sultan of the Delhi Sultanate.
Life

Ala-ud-Din Masud-Shah ruled from 1242 to 1246. He was the grandson of Iltutmish and the son of Rukn-ud-Din Firuz Shah. In practice, the Turkish nobles known as the Forty held all real power, leaving Masud-Shah only the Sultan’s title. A new Naib-i-Mamlikat post was revived and given to Malik Qutb-ud-din Hasan, while other top offices also went to members of the Forty. The Wazir, Muhazab-ud-Din, lost his position after clashing with these nobles, and Balban rose to become Amir-Hajib, eventually gathering most authority. Meanwhile, Tughra Khan, the Governor of Bengal, broke away, added Bihar to his domain, and even threatened Avadh. Multan and Uch also became independent. In 1245, Saif-ud-Din Hasan Qarlagh invaded Multan, but the Mongols arrived soon after, drove him out, and besieged Uch. When Sultan Mahmud advanced to the Beas River, the Mongols ended the siege and left. Ultimately, Balban, Nasir-ud-din Mahmud, and Nasir-ud-din’s mother conspired to overthrow Masud-Shah. By June 1246, Masud-Shah was deposed, and Nasir-ud-din Mahmud took the throne.[1]
