LAHORE DARBAR, i.e. the Sikh Court at Lahore, denoted the government of Maharaja Ranjit Singh and his successors (1799-1849). However, the Persian chroniclers refer to this government as Sarkar Khalsaji, and the term "Lahore Darbar" is not used even in British records until about the death of Maharaja Ranjit Singh. The composition of the Lahore Darbar was highly diversified. In the direction of all State affairs, political, foreign and domestic, it was completely subservient to the will of the Maharaja.
MEGH RAJ (d. 1864), the third son of Misr Divan Chand, starting as a clerk in Gobindgarh Fort at Amritsar under Maharaja Ranjit Singh, became head of the treasury at Amritsar in 1816. He held this position until the Maharaja`s death in 1839 soon after which Prince Nau Nihal Singh and Raja Hira Singh visited Amritsar to have his accounts checked. The accounts revealed no embezzlement, yet Megh Raj and his brother Rup Lal were taken into custody, and a fine of 5,00,000 rupees was imposed on them. They remained in captivity until Hira Singh`s assassination on 21 December 1844.
NANU MALL (d. 1791), minister and army general in Patiala state, was born at Sunam, in Sarigrur district. He came of a mercantile Aggarval family and became known as a highly capable administrator and a brave general. He acquired proficiency in classical languages Sanskrit, Arabic and Persian, and served in a civil capacity under Baba Ala Singh, founder of the Patiala dynasty. It was at the court of his successor, Maharaja Amar Singh, (1748-82), that Nanu Mall rose to be the Diwan of the state. In 1778, he was deputed by the Maharaja to assist Raja Gajpat Singh of Jind against Rahim Khan of Harisi, who had attacked his territory.
SULTAN MAHMUD KHAN (d. 1859) , son of General Ghaus Khan, was a commander of a section of heavy artillery during the regime of Maharaja Ranjit Singh. His derah of artillery was designated as Topkhanai Sultan Mahmud. After the death of General Ghaus Khan in 1814, although the chief command of the artillery was entrusted to Misr Divan Ghand, the battery under the former`s command was placed in the charge of Sultan Mahmud. Sultan Mahmud accompanied Maharaja Ranjit Singh on his expeditions against Multan and Kashmir. After the reorganization of the Sikh army into Brigades in 1835, when a horse battery was attached to each brigade, the heavy siege train continued to be commanded by General Sultan Mahmud as a separate corps.
ANNEXATION OF THE PUNJAB to British dominions in India in 1849 by Lord Dalhousie, the British governor general, which finally put an end to the sovereignty of the Sikhs over northwestern India, was the sequel to a chain of events that had followed the death of Maharaja Ranjit Singh ten years earlier. Internal dissensions and treachery had caused the defeat of the Sikh army at the hands of the British in the first Anglo Sikh war (1845-46). When on 16 December 1846, the Lahore Darbar was forced to sign the treaty of Bhyrowal (Bharoval), the kingdom of the Punjab was made a virtual British protectorate.
