v3.c42.s5.7

Early in the 17th century, Islam Khan, the viceroy of Bengal, recovered from the grasp of the Arrakanese the country east of the Meghna up to the Feni river, which thenceforth formed the eastern boundary of the Mughals. But here their further progress was arrested and during the next half century the Mag ascendency in the rivers and creeks of East Bengal became complete in consequence of Jahangir’s supine administration, the rebellion of his heir Shah Jahan, and the increase of the Arrakanese naval power by the infusion of a foreign element.*
