The weakening of the central political structure of the Mughal Empire and erosion of its military strength created some sort of a political vacuum in India- tempting ambitious Subedars and powerful regional chiefs to carve out semi independent or independent principalities for themselves.
Thus the eighteenth century saw the rise of a large number of autonomous states on the debris of the Mughal empire such as Bengal, Awadh, Hyderabad, Mysore, Marathas, Jats, Sikhs and Rajputs which is referred by many as a spectre of a fragmented polity.
