Firuz was the eldest surviving son of Iltutmish. Weak and irresponsible, he allowed his scheming mother to control him and, as a result, the sultanate began to fall into the hands of various factions. After a reign of only six months, he was seized and executed. All his coins are rare. As with the Dehli Tankas of his father, coins are found with varying amounts of dots in the segments on each side.
