Undivided Kamrup district

The administrative district of Kamrup was first constituted from the western portion of the Ahom kingdom then under the Burmese Empire that the British acquired following the Treaty of Yandaboo of 1826.

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.

[2] Guwahati, the headquarters of Undivided Kamrup district, was the political center of two of the three Kamarupa dynasties.

Soon after the invasion of Malik Ikhtiyaruddin Iuzbak in 1257 CE, Sandhya, a Kamarupa ruler, moved his capital to North Bengal and established the Kamata kingdom; but its control of the region that later came to be Undivided Kamrup district was lax.

[9] This region thus stopped being a political center till the capital of Assam was moved in the 20th century from Shillong to Dispur.
