Firoz Shah Tughlaq (Persian: فیروز شاہ تغلق‎, Hindi: फ़िरोज़ शाह तुग़लक़; 1309 – September 20, 1388) was a Turkic Muslim ruler of the Tughlaq Dynasty, who reigned over the Sultanate of Delhi from 1351 to 1388. He was the son of a Hindu princess of Dipalpur. His father's name was Razzab (the younger brother of Ghazi Malik). Firuz Shah Tughlaq succeeded his cousin Muhammad bin Tughluq following the later's death from a fatal illness, but due to widespread unrest Firuz's realm was much smaller than Muhammed's. Firuz Shah Tughlaq was forced by rebellions to concede virtual independence to Bengal and other provinces.
