Alauddin Khalji was the Sultan of Delhi from 1296 until his death in 1316. Alauddin instituted a number of significant administrative changes in the Delhi Sultanate, related to revenues, price controls, and society. He also successfully fended off several Mongol invasions of India.
Alauddin was a nephew and a son-in-law of his predecessor Jalaluddin. When Jalaluddin became the Sultan of Delhi after deposing the Mamluks, Alauddin was given the position of Amir-i-Tuzuk (equivalent to master of ceremonies). After suppressing a revolt against Jalaluddin, Alauddin obtained the governorship of Kara in 1291, and the governorship of Awadh in 1296, after a profitable raid on Bhilsa. In 1296, Alauddin raided Devagiri, and used the acquired loot to stage a successful revolt against Jalaluddin.
