United Kingdom

Although Britain and France had technically been at peace since 1748, both powers continued to harass each other in their colonial settlements in North America, the West Indies, and India. When the French attacked the British colony of Minorca in May 1756, war broke out; Britain allied itself with Prussia and France with Austria. Like every 18th-century war, this one began badly for Britain; it lost Oswego in North America as well as Minorca. There was an outcry in the press, and Newcastle and Fox resigned. In November Pitt was appointed secretary of state with William Cavendish, duke of Devonshire, serving as nominal head of the new administration. But Pitt, still lacking royal approval or an adequate majority in the Commons, was dismissed by the king in April 1757. He returned to power in June, forming what was to be a highly effective wartime coalition with Newcastle. Pitt captured the attention and imagination of Parliament and of the people by his rhetoric and charisma; Newcastle employed his experience and industry to raise more than £160 million during the course of the war. But what cemented the coalition was Britain’s naval and military successes. In India, where Britain and France were keen competitors, General Robert Clive captured the French settlement of Chandernagore and then, with the forces of the East India Company, defeated the army of Siraj-ud-Dawlah, the nawab (ruler) of Bengal, at the Battle of Plassey on June 23, 1757. The battle lasted only a few hours but decided the fate of India by establishing British dominance in Bengal and the Carnatic, the two most profitable regions of India for European traders. The year 1757, as a consequence, is often cited as the beginning of Britain’s supremacy over India, the start of Calcutta’s significance as the headquarters of the East India Company, and the beginning of the end of French influence on the subcontinent. Two years later large sections of the French fleet were destroyed at the naval battle of Quiberon Bay. When Quebec fell to General James Wolfe in 1759, British control of Canada was effectively secured. The island of Guadeloupe was captured in the same dramatic year, as were French trading bases on the west coast of Africa.

Most of these gains were confirmed by the Treaty of Paris (1763), though Britain restored Guadeloupe to the French in return for control of Canada. In the short term these victories resulted in a mood of patriotic exultation, especially among merchants. They looked to the new colonies to provide both fresh stocks of raw materials and eager markets for British manufactured goods: “Trade,” Edmund Burke gloated, “had been made to flourish by war.” This global victory, however, had been purchased at a high price. The conquest of Canada freed the American colonists from the fear of a French invasion from the north. Anxiety on this score had helped to foster American attachment to Britain. Now these fears had been relieved, and as early as 1760 some Britons and Americans anticipated that this would lead to difficulties. Furthermore, the enormous cost of the conflict led to drastic and sometimes damaging postwar economies, not least the deterioration of the Royal Navy, which would be an important factor in Britain’s defeat in the American Revolution (1775–83). Postwar economies also forced British governments to explore new fiscal expedients, which aroused discontent at home and in the American colonies. Finally, the apparent unity and strength of Britain’s elite during the Seven Years’ War was deceptive: Newcastle and many of his allies were elderly men, Pitt was difficult and unstable, and old Whig and Tory alignments had ceased to have much meaning. All these factors helped to make the early reign of George III a period of conflict and instability.

Political instability in Britain

George II died in October 1760 and was succeeded by his grandson, who became George III. The new king became one of the most controversial British monarchs. In the first 10 years of his reign administrations changed no fewer than seven times. In October 1761 Pitt resigned and Newcastle was made to share power with the royal favourite, John Stuart, earl of Bute. In May 1762 Newcastle too resigned, and Bute alone led the government until his resignation in April 1763. Bute was replaced by George Grenville, who was in turn dismissed in July 1765. For the next year Charles Watson-Wentworth, marquess of Rockingham, served as first lord of the treasury. But in July 1766 Rockingham was sacked and replaced by Pitt, now elevated to the House of Lords as earl of Chatham. Chatham soon lapsed into manic depression, and from 1768 to 1770 Augustus Henry Fitzroy, duke of Grafton, led the government. Only in 1770 did the king find a minister whom he felt he could trust and deal with: Frederick, Lord North. Such high political instability undoubtedly hampered British efforts to resolve the problem of its American colonies.
