Kamalganj Upazila: History
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. The battle between the Mughal Empire and Khwaja Usman was held in Patanushar, Kamalganj. This led to the death of Afghan leader Khwaja Usman.
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.
