After 22 February 1845 when Denmark sold all of its Indian assets to Britain the management and operation of the college continued without interruption under the direction of a master and council. In 1856 the Baptist Missionary Society in England took over the management of the college and, in 1857, the college became affiliated with the newly established University of Calcutta and became a constituent college of that university. In 1883 the college closed as an arts college and began functioning as a Christian Training Institution and a theological institute for the Baptist churches in Bengal.
