This daring project was at first triumphantly successful. The English had to follow suit in self-defence, but could not equal the ability of Dupleix. In 1750 a French protege occupied the most important throne of Southern India at Hyderabad, and was protected and kept loyal by a force of French sepoys under the Marquis de Bussy, whose expenses were met out of the revenues of large provinces (the Northern Sarkars) placed under French administration; while in the Carnatic, the coastal region where all the European traders had their south-eastern headquarters, a second French protege had almost succeeded in crushing his rival, whom the English company supported. But the genius of Clive reversed the situation with dramatic swiftness; the French authorities at home, alarmed at these dangerous adventures, repudiated and recalled Dupleix (1754), and the British power was left to apply the methods which he had invented. When the Seven Years' War broke out (1756), the French, repenting of their earlier decision, sent a substantial force to restore their lost influence in the Carnatic, but the result was complete failure. A British protege henceforward ruled in the Carnatic; a British force replaced the French at Hyderabad; and the revenues of the Northern Sarkars, formerly assigned for the maintenance of the French force, were handed over to its successor. Meanwhile in the rich province of Bengal a still more dramatic revolution had taken place. Attacked by the young Nawab, Siraj-uddaula, the British traders at Calcutta had been forced to evacuate that prosperous centre (1756). But Clive, coming up with a fleet and an army from Madras, applied the lessons he had learnt in the Carnatic, set up a rival claimant to the throne of Bengal, and at Plassey (1757) won for his puppet a complete victory. From 1757 onwards the British East India Company was the real master in Bengal, even more completely than in the Carnatic. It had not, in either region, conquered any territory; it had only supported successfully a claimant to the native throne. The native government, in theory, continued as before; the company, in theory, was its subject and vassal. But in practice these great and rich provinces lay at its mercy, and if it did not yet choose to undertake their government, this was only because it preferred to devote itself to its original business of trade. Thus by 1763 the British power had achieved a dazzling double triumph. It had destroyed the power of its chief rival both in the East and in the West. It had established the supremacy of the British peoples and of British methods of government throughout the whole continent of North America; and it had entered, blindly and without any conception of what the future was to bring forth, upon the path which was to lead to dominion over the vast continent of India, and upon the tremendous task of grafting the ideas of the West upon the East.
