This state of things continued during the rule of his two immediate successors, when we find Husamuddin Iwaz (a contemporary of Sultan Shamsuddin Altamsh) extending the frontier eastward to the Brahmaputra and southward to the sea-board, and reigning as an independent king under the title of Sultan Ghiasuddin (Tabaqat-i-Nasiri, p. 163). The Tarikh Firuz Shahi, p. 87 mentions that Emperor Balban in his pursuit of Mughisuddin Tughral, had to go so far eastward as Sunargaon, which would appear to have been within the limits also of Tughral's Bengal Kingdom. Again, in 1350 A.C. when Ibn-i-Batutah was in Chittagong, we find this important seaport was in the hands of King Fakhruddin of Sunargaon. As Mr. Thomas in his learned discussions on old coins of Bengal Musalman Kings has suggested, it would seem that so early as the twelfth century there was free commercial intercourse between the south-eastern sea-board of Bengal and the Arab seaports and one thousand and one hundred and fifty-eight infantry, one hundred and eighty elephants, and four thousand two hundred and six guns, four thousand and four hundred fleet of boats, constituted the standing army. Adjoining to the northern limits of Chittagong, is the tract of country ruled by the Rajah of Tipperah. It is an extensive country. The rulers of that country enjoy the title of Manik, for instance Nya Manik. The nobles have the title of Narain.
