For strategic and diplomatic reasons, Lord Minto concluded a treaty with Ranjit Singh at Amritsar in 1809 through Metcalf in order to check the Sikh advance beyond Sutlej. Sutlej was fixed as the boundry between the British East India Company and Maharaja Ranjit Singh. The forces of Maharaja Ranjit Singh ran over the Kashmir Valley in 1819 and Dogra general, Gulab Singh, the Raja of the State of Jammu. Gulab Singh ventured out to expand the boundaries of his empire, conquering Ladakh in the 1830s and Baltistan (in Pakistan) in the 1840s. At the same time that Gulab Singh was made the Raja of the State of Jammu, Maharaja Ranjit Singh gave to Dhyan Singh (Gulab Singh's brother), as a jagir, the district of Poonch (located in the Jammu and Kashmir).
