 Nasiruddin captured his capital Lakhnauti, and defeated and executed him on his return to Bengal.Following this conquest, the coinage in the Bengal region was issued in the name of Iltutmish, and the khutba in Lakhnauti was also read in his name.During the first half of the 1220s, Iltutmish had avoided Indus River Valley, which was contended by the Mongols, the Khwarazm kings, and Qabacha.
