There is a perception that the region of north east India maintained its ‘splendid isolation’ and remained outside the reach of the Mughals and did not have a pre-colonial past. The present book is an attempt to decenter and demolish the said perceptions and asserts that north east India did have a ‘medieval’ past through linkage with the dominant central power in India – the Mughals. The eastern frontier of this Mughal Empire was constituted by a number of states like Bengal, Koch Bihar, Assam, Manipur, Dimasa, Jaintia, Cachar, Tripura, Khasi confederation, Chittagong, Lushai and the Nagas. Of these, some areas like Bengal were an integral part of the Mughal Empire, while others like Koch Bihar and Assam were in and out of the empire. Tripura, Manipur, Jaintia and Cachar were frequently overrun by the Mughals whenever the State was short of revenue and withdrew soon without?incorporating?them?in?the?state.
