Firuz Shah Tughlaq
Firuz Shah Tughlaq (1309–1388) became sultan of Delhi in 1351 after the death of his cousin Muhammad bin Tughluq. The son of Sipahsalar Rajab and a Punjabi Hindu princess, he had been raised by his uncle Ghiyath al-Din.
His long reign brought campaigns in Bengal, Odisha, Kangra and Thatta, but he is best remembered as a builder: he founded Hisar, Fatehabad, Firozabad and Jaunpur and dug irrigation canals. He abdicated in 1387 and died in 1388 after a rule of thirty-seven years.
