Firuz Shah Tughlaq

Firuz Shah Tughlaq (; 1309 – 20 September 1388) was the 19th sultan of Delhi from 1351 to 1388. A Muslim ruler from the Tughlaq dynasty, He succeeded his cousin Muhammad bin Tughlaq following the latter's death at Thatta in Sindh, where Muhammad bin Tughlaq had gone in pursuit of Taghi the rebellious Muslim governor of Gujarat. For the first time in the history of the Sultanate, a situation was confronted wherein nobody was ready to accept the reins of power. With much difficulty, the camp followers convinced Firuz to accept the responsibility. In fact, Khwaja Jahan, the Wazir of Muhammad bin Tughlaq had placed a small boy on the throne claiming him to be the son of Muhammad bin Tughlaq, who meekly surrendered afterwards.

Due to widespread unrest, his realm was much smaller than Muhammad's. Tughlaq was forced by rebellions to concede virtual independence to Bengal and other provinces. He established Sharia across his realm. Provided by Wikipedia
