Atrai Upazila: History
It is said that Islam Khan I, a Mughal Subahdar of Bengal, passed through Atrai (hence many villages have names such as Islampur and Islamganthi) and constructed a mosque known as the Islamganthi Mosque in the seventeenth century. Atrai later came under the zamindari of the Mollah political family.
In 1916, Atrai was officially established as a thana. In 1968, the Mollah Azad Memorial College was founded in Atrai. During the Bangladesh Liberation War of 1971, a brawl emerged between the two factions in Bandaikhara on 19 September. Another encounter took place near Ghaulya and Taranagar. In a surprise attack, nine Pakistan Army ships were sunk. Its status was upgraded to upazila (sub-district) in August 1983 as part of the President of Bangladesh Hussain Muhammad Ershad's decentralisation programme.
