MAHĀṄ SIṄGH (d.1844), son of Dātā Rām, came to Lahore from Jammū at a very early age to seek his fortune in the Sikh capital Mahārājā Raṇjīt Siṅgh, who was struck by his skill and courage on a hunting expedition when Mahāṅ Siṅgh unassisted had killed a leopard with his sword, gave him an appointment in the army under Harī Siṅgh Nalvā. Young Mahāṅ Siṅgh fought in several campaigns with gallantry, and at the last siege of Multān in 1818 was twice wounded. He also served in Kashmīr and Peshāwar. He was in charge of the Fort of Jamrūd as Qilādār in April 1837 when the Afghān army attacked it in force. He held out bravely against enormous odds until Harī Siṅgh himself arrived from Peshāwar to fight the memorable battle in which he fell.

         Even after the death of his patron, Mahāṅ Siṅgh continued to enjoy the favour of the Mahārājā who, in 1839, gave him a jāgīr worth Rs 37, 000 of which Rs 12, 000 was personal and Rs 25, 000 for the service of 100 sovārs. He retained this estate throughout the reigns of Mahārājās Khaṛak Siṅgh and Sher Siṅgh.

         Mahāṅ Siṅgh was murdered by his own men in 1844. His descendants live at Mīrpur, in Jammū territory.
