On his request, Lord William Bentinck withdrew all of the European superintendents of civil departments and followed a policy of non-intervention in the Nizam's affairs. The Nizam founded the Hyderabad Medical School in 1846; he also owed large debts to the Arabs, the Rohillas and the British, and in 1853 he signed a treaty with the British during the reign of Governor-General The Earl of Dalhousie. The British agreed to liquidate all of his debts in return for ceding part of his territory to the British.
