Sialkot is one of the ancient cities of the Punjab. It is believed to have been founded by Raja Sul of Pando Dynasty whose heroic deeds were recorded in the Mahabharata, the sacred Hindu scriptures.  The place was originally called Sulkot which subsequently changed to Sialkot. During the British rule Sialkot was designated as a district. Its constituent revenue sub-districts (Tehsils) were Sialkot, Narowal, Shakargarh, Daska and Pasrur. In 1973 Narowal and Shakargarh Tehsils were separated to constitute Narowal district.
