Solution:During the reign of Nasiruddin Mahmud Shah, Ghiyasuddin Balban was appointed as his Prime Minister. Balban was the reason for the overthrow of Ala-ud-din Masud, placing Nasiruddin Mahmud as Sultan and himself as his Wazir from 1246 to 1265.
Mahmud married one of Balban’s daughters.
Balban also appointed Kishlu Khan, his younger brother, as lord chamberlain (Amir-i Hajib) and appointed his cousin, Sher Khan, to the Jagir of Lahore and Bhatinda.
