Princely states were autonomous principalities under the suzerainty of the British Crown in India. Initially, the Bengal Presidency managed the British government's relations with most princely states in the northern subcontinent, extending from Jammu and Kashmir in the north to Manipur in the northeast. An Agency was often formed to be the liaison between the government and the princely states. The largest of these agencies under Bengal once included the Rajputana Agency. Other agencies covered the Chota Nagpur Tributary States and the Orissa Tributary States. Agents were also appointed to deal with tribal chiefs, such as the three tribal kings in the Chittagong Hill Tracts. At the time of the partition of India in 1947, the jurisdiction of the Bengal States Agency included Cooch Behar State and Hill Tipperah.
