Note: Nasir ud-din Khusru was a former slave from Gujarat who, under Sultan Qutb ud-din Mubarak's rule in Delhi, rose to prominence. He repaid the sultan's favor by having him assassinated and seizing power as Nasir ud-din Khusru Shah. However, his rule was brief, and he was swiftly captured in battle and executed, leaving behind rare gold and silver coins from his short-lived reign.
