Ajmiriganj Upazila: History
In 1254, the Governor of Bengal Malik Ikhtiyaruddin Iuzbak invaded the Azmardan Raj (present-day Ajmiriganj). He defeated the local Raja. This was long before the Conquest of Sylhet in 1303. In the 1800s, a Sufi saint who was stationed at the Ajmer Sharif Dargah of Moinuddin Chishti, migrated to modern-day Ajmiriganj. His name was Syed Ishaq Chishti, and the locals referred to him as Ajmiri Baba (Baba of Ajmer). After the death of Ishaq, a government gazette notified that Abidabad thana would be renamed Ajmiriganj (Ganj of Ajmiri) in honour of Ishaq in circa 1907. Ajmiriganj amalgamated Bir Charan Govt Pilot High School was established in 1930. In 1983, Ajmiriganj thana was turned into an upazila. The names were changed from Aijadam > Ajmardan > Aijmadam > Abidabaad > Ajmiriganj.
During the Bangladesh Liberation War of 1971, an eighteen hour long encounter between the freedom fighters and the Pakistan Army took place on 16 November. 11 innocent villagers as well as freedom fighter Jagat Joity Das were killed.
