The Mahalwari system was one of the three major land revenue settlements of British colonial India introduced under the administration of East India Company. It was the last land settlement experimented by the company administration and expected to be an improvement over both the previous working settlements. The idea and proposal of Mahalwari system was first given by Holt Mackenzie, then the territorial secretary of the Board of Revenue, in his famous and detailed minute of 1st July 1819. The advice of Mackenzie’s minute was finally incorporated in the regulation VII of 1822 and became the basis of Mahalwari system. The Institutions of Lamberdars, Tehsildars and Patwaris played a very important and crucial role in the operation of the Mahalwari System of the land revenue settlement. A Lambardars was a village chief or head means the holder of a number of villages in the collector’s list of persons primarily responsible to bring in the land revenue of the village or a section of a village. He was usually a landlord or a zamindar, a taluqdar, or a proprietor or a patel. He was an official headman who had some authorized power in a Mahal. He acts as a representative of government in the village. A Tehsildar was the officer in-charge of a tehsil or subdivision of a district. He was the officer in-charge of a local treasury of a tehsil vested with powers either of a first grade or second grade assistant collector, according to their standing and experience. The Patwaris were appointed as a ‘village officer’ with amins, sazahwals, munsifs, and sherishtedars etc. to make the collections of land revenue. The Patwaris and qanungoes bound to work in close co-operation with the Lambardars. Here, I dealt the role and significance of the above mentioned institutions in the operation of the Mahalwari System.
