During the course of these two wars, and in the interval between them, an extraordinary series of events had opened a new scene for the rivalry of the two great imperial powers, and a new world began to be exposed to the influence of the political ideas of Europe. The vast and populous land of India, where the Europeans had hitherto been content to play the part of modest traders, under the protection and control of great native rulers, had suddenly been displayed as a field for the imperial ambitions of the European peoples. Ever since the first appearance of the Dutch, the English, and the French in these regions, Northern India had formed a consolidated empire ruled from Delhi by the great Mogul dynasty; the shadow of its power was also cast over the lesser princes of Southern India. But after 1709, and still more after 1739, the Mogul Empire collapsed, and the whole of India, north and south, rapidly fell into a condition of complete anarchy. A multitude of petty rulers, nominal satraps of the powerless Mogul, roving adventurers, or bands of Mahratta raiders, put an end to all order and security; and to protect themselves and maintain their trade the European traders must needs enlist considerable bodies of Indian troops. It had long been proved that a comparatively small number of troops, disciplined in the European fashion, could hold their own against the loose and disorderly mobs who followed the standards of Indian rulers. And it now occurred to the ambitious mind of the Frenchman Dupleix that it should be possible, by the use of this military superiority, to intervene with effect in the unceasing strife of the Indian princes, to turn the scale on one side or the other, and to obtain over the princes whose cause he embraced a commanding influence, which would enable him to secure the expulsion of his English rivals, and the establishment of a French trade monopoly based upon political influence.
