Sialkot became a part of the Muslim Sultanate of Delhi when the Afghan noble Sultan Shahab-ud-Din Muhammad Ghauri conquered Punjab in 1185. He was unable to conquer Lahore but left a garrison in Sialkot. Later Sultan Khusro Malik tried to capture the city but failed to do so. Sialkot then became a part of the Muslim Mughal Empire. The Mughal commander Usman Ghani Raza, advanced towards Delhi by way of Sialkot which capitulated to his armies.
