Companiganj (Bengali: কোম্পানীগঞ্জ) is an upazila of Noakhali District.[1] Basurhat is the only municipality in this upazila. The area is famed for water buffalo doi (curd).[2]
The Port of Jugdia (presently in Sirajpur Union) gained relevance as an important commercial seaport during the Bengal Sultanate period. With the advent of the Mughals, the Eidagazi Mosque was constructed in Charhazari. In 1853, the British East India Company set up a factory in Jugdia and a textile mill there in 1857. The French East India Company also set up huge textile mills here and these textiles and salt, including the native textiles produced by the Tantis, were exported abroad through the Port of Jugdia. Companiganj was established as a thana (police outpost) in 1888, by the British colonial administrators, named after the British East India Company.[1] The map of Companiganj and Sandwip Upazila at the mouth of the Meghna River estuary and at the confluence of the Bamni rivers changes every few years. During the British rule, there was a Bamni Thana in this area (in Rampur Union). There are also villages named Bamni and Musapur in Sandwip. It is known that people from these two areas emigrated from Sandwip due to river breakage. These two regions of Companiganj and Sandwip had close contact even until the 1960s. The people of Bamni in Sandwip were reportedly the descendants of a Brahmin woman, and when they migrated to Bamni (Rampur), it caused issues due to the class and cultural differences. The Sandwipis of Companiganj are said to maintain a distinct identity to the native Companiganjis.[2]
The 20th century marked an important development of Islamic education in Companiganj. In 1915, the Asria Senior Madrasa was established in Bamni. Eight years later, the Islamia Senior Madrasa was founded in Basurhat. During the Bangladesh Liberation War of 1971, a Razakar force was established in Companiganj by the grandsons of Moulvi Minnat Ali of Bamni. One of their brothers, Rafi Uddin, became the central leader of the Al-Badr force. When the freedom fighters went to liberate the Charfaqira Union by setting up base at the nearby Chaprashi market, freedom fighter Abdur Rob was killed. Salih Ahmad and others were killed by a surprise attack by the Razakars.[2] A brawl took place near the sluice gate on Banchharam Road between the Bengali freedom fighters against the Pakistan Army and their collaborators on 4 September. As a result, six freedom fighters were killed. A number of other encounters took place in Companiganj, with the Liberation of Bamni leading to the death of seven freedom fighters including Sadar BLF Commander Ohidur Rahman Wadud. Their bodies lie in a mass grave near Sluice Gate no 16.
On 2 July 1983, Companiganj Thana was upgraded to an upazila (sub-district) as part of the President of Bangladesh Hussain Muhammad Ershad's decentralisation programme.[1]
Companigani is bounded by Senbgh and Daganbhuiyan upazilas on the north, Noakhali Sadar and Sandwip on the south, Sonagazi and Mirsharai on the east, Noakhali Sadar on the west. The main rivers are Little Feni and Bamni.
