After he became the Sultan, he indulged in the life of wine and women, and the example set by the Sultan was also followed by his courtiers. He was not as much a pious
Muslim as his predecessors as he did not focus on his
Islamic studies as much. His army met with his father
Bughra Khan's
Bengal army in Northern
Bihar, but due to the love for his father he ran towards him to embrace his crying. No battle took place and a lasting peace treaty was agreed between Bengal and
Hindustan, which was even respected by his successors. On his return to
Delhi, he transferred Nizam-ud-Din to
Multan, seeing the latter's hesitation, the Sultan ordered him to be poisoned. He appointed
Jalal-ud-din Khalji as a new commander of the army, but the murder and appointment sent a wave of dissent amongst the Turkic nobility. Taking advantage of this Jalal-ud-Din Firuz marched his army to
Delhi. After four years, he was murdered in 1290 by Jalaluddin Khilji. His infant son,
Kayumars, was also murdered, ending the
Mamluk Dynasty and instigating the
Khalji Revolution. == Coinage ==
