<P> Undivided Kamrup district is a former administrative district located in Western Assam from which Kamrup Rural (2003), Kamrup Metropolitan (2003), Barpeta (1983), Nalbari (1985) and Baksa (2004) Kamrup South (2015) districts were formed . It was large administrative district in colonial times that has been reducing its size in subsequent periods . </P> <P> The administrative district of Kamrup was first constituted from the western portion of the Burmese Empire that the British acquired following the Treaty of Yandaboo of 1826 . The western boundary of this district was the Manas river, and the eastern boundary of this district was the Barnadi river . After 1826 the British administered the newly acquired regions via two commissioners: the Senior Commissioner who administered the "North - East of Rangpur" (largely the undivided Goalpara) in addition to the newly acquired region between Manas river and Biswanath; and the Junior Commissioner, who administered the region to the east of Biswanath . In March 1833 the British established district administration in the region west of the Dhansiri river, with the Kamrup district originally envisaged as two separate districts among 3 others: the six parganas largely co-terminus with present - day Barpeta and Nagarberra; and the twenty parganas in the north and six duars in the south . Each district were to be administered by a Principal Assistant, deputed by a Junior Assistant . But due to a paucity of funds, the six pargana region had only a Junior Assistant, and by 1836, the Kamrup district acquired its "undivided" form and name . </P>
