Jalal-ud-din Khilji, the founder of the Khiliji Dynasty was regarded as a foreign intruder. Kaiqubad appointed him as `Ariz-I-Mumalik`. At that time Sultanate of Delhi was facing a political vacuum due to the incapability of the successors of Balban. That was a great time to occupy the throne of Delhi. Malik Firuz removed the Infant Sultan Kaimurs and ascended the throne as Jalal-ud-din Firuz Shah.

A man of generosity managed to win the heart of Turkish Muslim majority population in Delhi. He retained most of the officers who were holding the key positions during the Slave dynasty. He was on the throne only for 6 years from 1290 to 1296. In 1292 the Mongols Invaded India but his intelligent negotiation forced the Mongols to withdraw.

His nephew cum son-in-law Alauddin killed him in the year 1296. With such a short period of his reign he should be remembered as the founder of such a dynasty that laid the foundation of Indian economy.
