Reign of Firos tughlaq
Post the demise of Mohammad-bin-tughlaq, Firos tughlaq who is the son of Mohammad-bin-Tughlaq's brother took over the empire, he showed little interest in regaining the territories that have been lost during these years and he couldn't suppress the rebellions.
 
During his period the positions of army and nobility were made hereditary. In addition to that, the Iqta system was also made hereditary.

Among other sultans Firos was more generous and compassionate towards people, he also took advice from Sufis ( religious scholars) and rewarded them fittingly.
 
To earn the Goodwill of theologians the Sultan took some steps like prohibiting Muslim women to go out for worship and giving concessions to the theologian community.

Also established charities to help people, colleges, mosques and hospitals were also built. He once declined an invite from the Bahman sultan to intervene in Deccan affairs, later he banned barbaric punishments and abolished taxes that are not in line with Muslim law.

  • To take his penchant for architecture to greater heights he also established numerous towns Firosabad, Jaunpur, Hissar and Firospur to name a few.
