Dhian Singh Dogra was the longest serving prime minister of the Sikh empire, during the reign of its first Maharajah Ranjit Singh, and four of his heirs. He held the office for twenty five years, from 1818 up till his death. The Dogra are a Rajput clan from Jammu region and speak Dogri language, a dialect of Punjabi. Dogra Rajputs origially from the Punjab foothills, migrated to the Shivalik Hills to escape the marauding Islamic invaders from Turkey. In the turbulent four years following the emperor's death on 27 June 1839, Dhian remained at the helm, grappling with a power struggle in which three successive emperors and one empress died suddenly, in the build-up to the First Anglo-Sikh War. Following the coronation of Kharak Singh on 1 September 1839, Dhian launched a palace coup on 8 October 1839, and assassinated Chet Singh Bajwa, the favourite courtier of the emperor. He imprisoned emperor Kharak, who later died of slow poisoning by lead and mercury. Dhian had spread rumor that the hedonistic emperor intended to sell out the sovereignty of the Sikh empire to the British East India Company. Dhian then installed the emperor's son Nau Nihal Singh, aged eighteen, to the throne. Thirteen months later, emperor Nau Nihal, died suddenly on 5 November 1840, on the day of his father's funeral. After leaving the funeral pyre, Nau Nihal was knocked unconscious when a stone gate at Lahore Fort collapsed upon him. Dhian had the emperor carried indoors, and barred any visitors, including the emperor's mother Chand Kaur. Eyewitness accounts had initially reported the emperor had minor injuries from the accident, however later the emperor was pronounced dead when Dhian presented the corpse with its head smashed. AmericancolonelAlexander Gardner, who was with Nau Nihal when he was injured, noted that five artillery men carried the emperor into the fort under the orders of Dhian. Two of these men died mysteriously, two asked for leave and never returned, and one inexplicably disappeared. On 13 January 1841, Sher Singh led a coup against empress Chand Kaur, and after two days of siege and battle, Dhian negotiated a ceasefire, which led to empress Chand's abdication, and Sher succeeding to the throne as emperor. Later, Dhian had the deposed empress's servants changed, who then assassinated Chand in her palace by smashing her head with wooden pikes on 11 June 1842. Dhian and emperor Sher were both assassinated on 15 September 1843, in a plot led by Ajit Singh Sandhawalia. Dhian was shot and his body cut into pieces. Dhian's son Hira Singh Dogra led a counter-coup the next day, and killed the assassins. On 17 September 1843, Hira Singh Dogra, aged 24, succeeded his father as the prime minister, with five year old infant Duleep Singh being crowned emperor. Dhian's younger brother Suchet Singh Dogra was killed on 27 March 1844, while leading a failed coup against Dhian's son Hira Singh Dogra. Hira himself was assassinated following another coup d'etat led by Sham Singh Atariwala on 21 December 1844. A year later the First Anglo-Sikh War broke out on 11 December 1845. Dhian's elder brother MaharajahGulab Singh Dogra, was the prime minister of the Sikh empire from 31 January – 9 March 1846, during the First Anglo-Sikh War, and then became the first emperor of Jammu and Kashmir on 16 March 1846, by the Treaty of Amritsar. This followed the 9 March Treaty of Lahore and ultimately led up to the BritishEast India Company gaining sovereignty over the Sikh empire.
