Chittagong region was under the kingdom of Arakan during sixth and seventh centuries. Before the Muslim rule Chittagong had been either under the control of the Arakans or under the kings of Burma. Sultan Fakruddin Mubarak Shah of Sonargaon conquered Chittagong in 1340. After the defeat of Sultan Giasuddin Mahmud Shah in the hands of Sher Shah in1538, the Arakanise again captured Chittagong.
