Cachar was another native kingdom that fell victim to the imperialist design of the British. The Kingdom of Cachar was being ruled by two rulers having clearly defined areas of control. In the plains (southern portion of Cachar) Govindrachandradwajanarayana Hasnu was the ruling prince. Immediately after his assassination by Gambhir Singh, then king of Manipur, British annexed it to their dominion in India (1832). Tularam was the ruling chief of the hilly tract (northern portion of Cachar or Dima Hasao). His territories were annexed after he died in 1854. Thus entire Cachar came under the British occupation. While south Cachar was annexed under Robertson, the hilly tract of Cachar came under British occupation when Jenkins was the Commissioner of Assam.In 1916,it was the Commissioner of Pakokku Hill Tracts until 1947.
