Kachua Upazila, Chandpur
Kachua () is an upazila (sub-district) of Chandpur District in Bangladesh, located in the Chittagong Division. It is a part of the Greater Comilla region. History

During the reign of the Mughal emperor Bahadur Shah in 1705/1706 CE, the Faujdar (local governor) Bakhtiyar ibn Ilyas Khan built a mosque in Ujania which still stands today. The area was also settled by a wali known as Shah Niamat Shah, who was based on the banks of the Tarini Dighi. People from various places would travel to meet with the Wali, and a haat bazaar later emerged known as Niamat Shaher Bazar (Niamat Shah's bazaar). It is presently known as Kachua Bazar after the establishment of Kachua Thana. During the time of the administration of the British East India Company, Kachua was a part of the Daudkandi Thana. A large portion of present-day Kachua was under the zamindari of the Munshibari family of Comilla. Abdul Hamid Munshi of this family was responsible for establishing the glorious Taltoli Jama Mosque in the village of Taltoli in 1891. By the time of Queen Victoria, Kachua was under the Hajiganj Thana. A separate thana was established with the name of Kachua on 25 January 1918 during the reign of George V. There are numerous theories behind the naming of Kachua. One theory suggests that it is of Hindustani origin. It was said that in 1905, the Hajiganj Thana was divided into two parts and survey work was carried out to determine its boundary/area. The survey was conducted under the leadership of a police officer. The survey work started from the southern boundary of Daudkandi Thana i.e. the northern end of present Kachua Upazila. At one stage of the survey, the police officer and other people came to the southern part of the village on the north side adjacent to Kachua Bazar and found some palm trees. They camped for a few days in a high place in this palm tree area which is now known as Dhulikachua village. A local villager by the name of Maulvi Ali Akmat asked how much of the survey work had been done and in reply, the officer said "Kuch Hua" meaning some things have happened. The name Kachua was said to have been derived from "Kuch Hua" according to this incident. During the Bangladesh Liberation War of 1971, a brawl took place in Raghunathpur Bazar leading to the death of one Bengali freedom fighter and 14 civilians. Kachua Thana was upgraded to an upazila in 1983. Geography
