In 1779, the Khasi people attacked merchants in the village of Pandua in Bholaganj, who were going towards Calcutta after they experienced abuse from Europeans. Many merchants pleaded Robert Lindsay, the Collector of Sylhet, to build a small brick fort to protect them from further attacks from the Khasi. In 1789, the Collector of Sylhet, John Willes, stationed many sepoys in Pandua. The Khasi however, continued their attacks, killing the thanadar and many sepoys. Two European merchants managed to escape and inform Willes of the incident, who passed it on to the Government at Calcutta. A force was then sent from there to the village of Pandua, although it led to a bloodless end. Willes also told the government that he really had little control over northern Sylhet as the Khasi chiefs refused every order, would behead the messenger and then continue raiding Sylheti villages as they had done even during the Mughal Empire period. Another Khasi raid took place in 1795 and many years went after that with the Khasis remaining in their hills and not troubling the plains. In 1976, the Companiganj Thana was established based in the village of Burdeo in the banks of the Dhalai River. It consisted of the current Companiganj Upazila but also included Islampur Union, Jalalabad Union as well as Rustampur & Towakul Unions. The reason for the creation of a thana was because there were no main roads leading to the town and the only access was through rivers during the rainy season. The East India Company had a strong presence in the business sector in this area and thus it was named Companiganj. During the Bangladesh Liberation War of 1971, Companiganj was part of the Bholaganj sub-sector in Sector 5 under the charge of Lieutenant Taheruddin Akhunji. 19 freedom fighters were killed in this area. It was made an upazila on 11 November 1982 by the President of Bangladesh, H M Ershad, as a part of his decentralisation programme.
