Jalal-ud-Din Ahsan Khan
Jalaluddin Ahsan Khan declared independence from Delhi Sultanate around 1335 CE. His daughter was married to the historian Ibn Battuta and his son Ibrahim was the purse bearer of Muhammad bin Tughluq. When Tughluq heard of Jalaluddin's rebellion he had Ibrahim killed in retaliation. Jalaluddin is variously referred to as "Syed", "Hasan" or "Hussun" by the historians Firishta and Ziauddin Barani. Tughluq tried to conquer Ma'bar back in 1337 CE. But he fell ill at Bidar on the way to Ma'bar and had to return to Deogiri. His army was defeated by Jalaluddin. Jalaluddin was killed by one of his nobles in 1340 CE.
