Kamalganj (Bengali: কমলগঞ্জ) is an upazila of the Moulvibazar District[2] in the Division of Sylhet, Bangladesh.
There was a local zamindar by the name of Kinkar Nath Ray who appointed a naib by the name of Kamal Narayan in order to develop the land. Kamal established a ganj (treasured neighbourhood) named after himself. In 1922, Kamalganj was made a thana and in 1983, an upazila.[3]
Kamalganj was a part of the ancient Ita Kingdom founded by Raja Bhanu Narayan. The final raja of the Ita Kingdom, Raja Subid Narayan lost a battle in 1610 in which the region became under the rule of Khwaja Usman. However, this rule was short-lived after Mughal General Islam Khan I's attack in 1612.[4] The battle between the Mughal Empire and Khwaja Usman was held in Patanushar, Kamalganj. This led to the death of Afghan leader Khwaja Usman.[5]
A peasant rebellion (krishokproja bidraho) against zamindar of Prithimpasa led by Manipuri leader Panchanan Singh, Baikunthanath Sharma,Themba Singh and Qasim Ali was held in the 1900s in Bhanubil, Kamalganj.[6]
