 Iltutmish largely remained away from this region until the departure of the Mongols and Jalal ad-Din, engaging in minor skirmishes only when he saw a danger to his own territories in India.After the departure of Jalal ad-Din from India in 1224, Iltutmish turned his focus towards eastern India, where Aibak's former subordinates had carved out an independent kingdom headquartered at Lakhnauti.Iltutmish extracted tribute from the local ruler Ghiyasuddin Iwaj Shah in 1225, and annexed the region in 1227 after an unsuccessful rebellion by Ghiyasuddin.
