However, in that year, Sylhet was moved to the newly created Assam Province, and it remained as part of Assam up to 1947 (except during the administrative reorganisation of Bengal Province between 1905 and 1912). Sylhet District was divided into five subdivisions and the current Sylhet District was known as the North Sylhet subdivision. In 1947, Sylhet became a part of East Pakistan as a result of a referendum (except 3 thanas of Karimganj subdivision) as part of Chittagong Division.
