Muhammad bin Tughluq (also Prince Fakhr Malik Jauna Khan, Ulugh Khan; c. 1290 – 20 March 1351) was the Sultan of Delhi from 1325 to 1351. He was the eldest son of Ghiyas -ud -Din -Tughlaq, the founder of the Tughluq dynasty. His wife was the daughter of the Raja of Dipalpur. Ghiyas-ud-din sent the young Muhammad to the Deccan to campaign against king Prataparudra of the Kakatiya dynasty whose capital was at Warangal in 1321 and 1323. Muhammad has been described as an "inhuman eccentric" with bizarre character by the accounts of visitors during his rule. He is also known for wild policy swings. Muhammad ascended to the Delhi throne upon his father's death in 1325.
