Muhammad bin Tughluq, Sultan of Delhi
Mohammad bin Tughlaq (also known as 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 Tughlaq dynasty. 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 said to have ordered the massacre of all the inhabitants of the Hindu city of Kannauj. He is also known for wild policy swings. Muhammad ascended to the Delhi throne upon his father's death in 1325.

He was interested in medicine and was skilled in several languages — Persian, Arabic, Turkish and Sanskrit. Ibn Battuta, the famous traveler and jurist from Morocco, was a guest at his court and wrote about his suzerainty in his book.
