Mansa district was formed on 13th April 1992 from the erst while district of Bathinda. Mansa is a small district both in terms of population and area. It is situated on the rail line between Bathinda-Jind-Delhi section and also situated on Barnala-Sardulgarh-Sirsa Road.
The town is said to have been founded by Bhai Gurdas who hailed from Dhingar, Distt. Mansa. He is said to have been married at this place among the Dhaliwal Jat Sikh. Once he came to his in-laws to take his wife alongwith him but they refused to send her. At this, Bhai Gurdas sat in meditation before the house of his in-laws. After some time, the parents of the girl agreed to send their daughter with Bhai Gurdas. But he refused to take her alongwith him, stating that he had now renounced the worldly way of life. In his memory, his Smadh was constructed where a fair is held every year in March-April. People in large numbers attend the fair and offer Laddus and Gur at Smadh. Class ‘A’municipality has been functioning in the town since 1952.
