IMĀM UD-DĪN, SHAIKH (1819-1859), who succeeded his father, Shaikh Ghulām Mohīy ud-Dīn, as governor of the Sikh province of Kashmīr in 1845, had earlier served under Kaṅvar Nau Nihāl Siṅgh in the Ḍerājāt and had in 1840 assisted his father in the campaign against Maṇḍī. In April 1841, when a mutiny occurred in Kashmīr, Mahārājā Sher Siṅgh ordered his father, Sheikh Ghulām Mohīy ud-Dīn, then governor of the Jalandhar Doāb, to proceed to Kashmīr to take charge of the province and restore order. Shaikh Imām ud-Dīn was then appointed governor of the Jalandhar Doāb. When in September 1843, Wazīr Hīrā Siṅgh had Bhāī Gurmukh Siṅgh and Misr Belī Rām arrested, he handed them over to Shaikh Imām ud-Dīn for custody. Imām ud-Dīn kept them in the stables near his house in Lahore. Within a week of their confinement, both of them were put to death at Hīrā Siṅgh's orders. Shaikh Imām ud-Dīn was also involved by Hīrā Siṅgh in the plot to destroy the ḍerā of Bābā Bīr Siṅgh of Nauraṅgābād which fell within his jurisdiction. During the insurrection in Kashmīr in 1844 when Shaikh Ghulām Mohīy ud-Dīn asked for reinforcements from the Lahore Darbār, Shaikh Imām ud-Dīn was sent with a contingent to help him. On the death of his father, Imām ud-Dīn took over as governor of Kashmīr, with the title of Amīn ul-Mulk Jaṅg Bahādur. His fortune, however, declined with the conclusion of the Anglo-Sikh treaty of 16 March 1846, according to which Kashmīr was to be handed over to Gulāb Siṅgh. The arrangement was resented by Rājā Lāl Siṅgh, minister to the Lahore Darbār, who in a private communication instructed Shaikh Imām ud-Dīn to obstruct it. Shaikh Imām ud-Dīn was ultimately overcome by the intervention of the British under Major Henry Lawrence to whom he surrendered. He was tried at Lahore by a commission comprising Major-General Littler, Lt-Colonel Lawrence, Lt-Colonel Goldie, Mr Currie and Mr Lawrence, but was exonerated when he produced original letters written by Rājā Lāl Siṅgh. His property in Lahore, which was earlier confiscated, was restored to him.
In June 1848, Shaikh Imām ud-Dīn went at the head of 2, 000 troops to assist Herbert Edwardes in the reduction of Multān, and succeeded in arresting Naraiṇ Siṅgh, commander of Dīwān Mūl Rāj. He was later rewaded with the title of Nawāb and Bahādur, together with a pension of Rs 11, 600 and confirmation of his jāgīr of Rs 8, 400. Again in 1857, he helped the British raise two contingents of cavalry to fight on their behalf in Delhi. He died in March 1859 at the early age of 40 and was buried in the vicinity of the tomb of the famous saint, Dātā Gañj Bakhsh, at Lahore.
