murders and land-grabbing increased during Nasir-ud-Daulah's reign, and bribery and corruption became commonplace. The zamindars exploited the labourers. Fathulla Khan, a minister of the Nizam, said these activities occurred because of the withdrawal of British officers. In 1835, the Court of Directors of the East India Company revolted and wrote to the British government that there was a breakdown of law and order in the state of Hyderabad and that they could not ignore the misrule. In response, Nasir-ud-Daulah appointed some government workers as confidential servants to various districts of the state to monitor the activities of revenue officers, to suppress any oppression and to administer justice. The servants, however, were illiterate mansabdars (military officers) of low rank, and this system failed. These servants instead became agents of the taluqdars (landed gentry), who misused them to extort money from private individuals. Four years later, the Court of Directors wrote a similar letter. Nasir-ud-Daulah's younger brother, Prince Mubarez-ud-Daulah was inspired by the Wahhabi movement in India and had become fiercely opposed to the continued presence of the East India Company on the Indian subcontinent, allegedly formulating plans to overthrown both them and the Nizam. He struck a deal with Rasool Khan, the Nawab of Kurnool. With the help of his agents, the Resident of Hyderabad James Stuart Fraser intercepted their plans, then accused Mubarez-ud-Daulah of planning a conspiracy against Nasir-ud-Daulah. On 15 June 1839, Nasir-ud-Daulah ordered an attack on the palace of Mubarez-ud-Daulah, so that Mubarez-ud-Daulah could be arrested and held at Golconda Fort. Mubarez was successfully imprisoned, he remained so until his death in 1854. Under the guidance of Prime Minister Siraj-ul-Mulk (until his death in 1853) and the next Prime Minister Salar Jung I, Nasir-ud-Daulah established a modern revenue administration system. The kingdom was divided into 16 districts, each of which was administered by a taluqdar who was responsible for its judicial and civil administration. In 1846, Nasir-ud-Daulah founded the Hyderabad Medical School, which is now known as Osmania Medical College. He was interested in recruiting both men and women for the medical field. By 31 December 1850, Nasir-ud-Daulah's debts to the British had reached . By mid-1852, he found it difficult to pay his own officers. In 1853, he signed a treaty with the British government, during the rule of Governor-General The Earl of Dalhousie. According to this treaty, the British agreed to liquidate his debts in return
