Chittagong had been a sea port since the ancient time. The Arab traders had business transactions with this port since 9th century AD. 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. From this time onward until its conquest by the Mughals this region was under the control of the Portuguese and the Magh pirates. The Mughal Commandar Bujurg Umed Khan expelled the Portuguese from the area in 1666 and established Mughal rule there. The Mughals renamed Chittagong as Islamabad.
