Even when he assumed ruling powers, Sahib Singh, was guided and helped by his sister, Sahib Kaur, who by her strong leadership saved the state in 1794 from usurpation by the Marathas. After Sahib Kaur`s death the real power passed into the hands of Rani As Kaur, the Raja`s wife. Raja Sahib Singh died at Patiala on 26 March 1813. It was during his rule that the state came under British protection.
