[3][4] Baniachong constituted the grand estate (zamindari) of Anwar Khan, who was looked upon as a raja by the local people.

Estate of Baniachong was so vast, it crisscrossed all districts of Sylhet region as well as the greater Mymensingh, Dhaka and Comilla.

Hence, these 28 Parganas: Banshikunda (Vamshikunda), Ranadigha, Shelvarsh, Sukhaid, Bétaal, Palash, Laxmanshree, Chamtala, Pagla (Paragala), Dohaliya, Bazu Jatua, Sinchapaid, Shafahar (Shaharpara), Sik Sonaita (Sonauta), Atuajan (Atuajahan), Aatgaon, Kuwazpur, Joar Baniyachung, Kasba Baniyachung, Jalsuka, Bithangal, Joanshahi, Mudaikaid (Mudakadi), Kuresha, Jantari (Yantri), Haveli Sonaita, Satar Sati and Paikuda, were allotted to new landholders that created numerous zamindars and taluquedars in former Muazzamabad (districts of Sunamganj and Habiganj).

This was achieved through a severance scheme conjured up by a shrewd dewan; this scheme made the zamindar honour-bound to grant land (taluque) to his servants on retirement and there were two categories of taluque: (i) Khalisa and (ii) Mujrahi, aka Mujrai.

Baniachong had a literacy rate (age 7 and over) of 34.65%, compared to the national average of 51.8%, and a sex ratio of 1029 females per 1000 males.
