Muiz ud din Bahram
Muiz ud-Din Bahram (9 July 1212 – 15 May 1242, ) was the sixth sultan of the Mamluk Dynasty. Life 
He was the son of Shams ud din Iltutmish (1211–36) and the half-brother of Razia Sultan (1236–40). While his sister was imprisoned in Bathinda by subedar Malik Altunia (both Altunia and Bahram Shah planned conspiracy against Razia Sultan) he declared himself the king with the support of forty chiefs. Even so, during Muiz ud din Bahram's two years as king, the chiefs that had originally supported him became disordered and constantly bickered among each other. It was during this period of unrest that he was murdered by his own army in 1242 (died 15 May 1242). After his death, he was succeeded by his nephew Ala ud din Masud, a son of his half-brother Rukn ud din Firuz. Ögedei Khan of the Mongol Empire appointed Dayir commander of Ghazni and Menggetu commander in Kunduz. In winter 1241 the Mongol force invaded the Indus valley and besieged Lahore. Dayir died storming the town, however, on 30 December 1241, and the Mongols butchered the town before withdrawing from the Delhi Sultanate. The sultan was too weak to take step against them. The "Forty Chiefs" besieged him in the White Fort of Delhi and put him to death. After the death of Razia Sultan (1240) the forty chiefs decided to put Iltutmish's third Son Bahram shah on the throne. He was put on throne on 21 April 1240 at Lal Mahal but after some time the 40 chiefs decided to take all the power of Bahram shah in their hands. At that time the Minister was Muhajbuddin, so in this way there was three rulers of that dynasty. Muiz ud din Bahram built a mosque in Delhi during his reign.
