Sultanpur is an ancient town (in the present district of Kapurthala), about 25 km from Kapurthala and about 45 km from Jullundur. According to a tradition, this city was founded by Sultan Khan Lodhi (a general of Sultan Mehmood of Ghazni), on the ruins of erstwhile Sarbnam city. According to another tradition Sultan Khan (son of Wali Mohammed Khan, the Governor of Punjab), founded this city in 1332. For the next three centuries, this town remained the headquarters of the chief of the sub-province of Jalandhar-Doab. Guru Nanak Sahib, the founder of Sikhism, spent 3 years (September 1504 – 20.8.1507) in this city. Guru Arjan Sahib too visited this city. In 1739, Nadir Shah invaded, plundered and destroyed the town. Sirdar Jassa Singh Ahluwalia occupied it in November 1753.
There are several Gurdwaras in the city: 1. Gurdwara Ber Sahib (Here, Guru Nanak Sahib used to have bath every day. A Ber tree, believed to be from the time of Guru Sahib, still exist; hence the name of the Gurdwara). 2. Gurdwara Hatt Sahib (Here, Guru Sahib worked as chief of the royal store). 3.
