Aditmari Upazila: History
Aditmari was historically a part of Kaliganj thana. This area was formerly part of a chakla governed by Indra Narayan Chakravarti during the reign of Maharaja Madan (Moda) Narayan (1665–1680) of Koch Bihar. Ibadat Khan, the Mughal faujdar of Ghoraghat, led an expedition against Koch Bihar in 1687, incorporating the region into the Bengal Subah once again. Nawab Nuruddin Muhammad Baqer Jang, his minister, Raja Dayashil of Qadamtala (Moinpur) and local supporters were punished by the forces of Captain McDonald in this area, which came to be known by the locals as "Aadatmara". It later got corrupted to Aditmari.
On 10 April 1981, the government of Bangladesh established a thana in Aditmari, taking eight unions from Kaliganj thana. The status of Aditmari thana was upgraded to upazila (sub-district) on 7 November 1983, as part of the President of Bangladesh Hussain Muhammad Ershad's decentralisation programme.
During the Bangladesh Liberation War of 1971, Aditmari thana was under Sector No. 6 led by Khademul Bashar. Several houses in Aditmari were set on fire by the Pakistan Army on 4 April. The army executed innocent civilians in Lalpur, which is located to the east of Aditmari railway station. A mass grave can be found in Batrish Hazari High School field. The area was liberated by Bengali freedom fighters on 6 December.
