The War of the Austrian Succession ended with the Treaty of Aix-la-Chapelle (1748), which, as far as Britain was concerned, restored the territorial status quo. By then, a series of short-lived ministries had given way to the relatively stable administration of Henry Pelham. During the mid-1750s the British found themselves fighting an undeclared war against France both in North America (see French and Indian War) and in India. In 1756 formal war broke out again. The Seven Years’ War (1756-1763) pitted Britain, allied with Prussia, against France in alliance with Austria and Russia. For Britain the war began with a series of defeats in North America, in India, in the Mediterranean, and on the Continent (where the French overran Hannover). Under strong popular pressure, King George II then appointed the fiery William Pitt the Elder as the minister to run the war abroad, while his colleague, the duke of Newcastle, oiled the political wheels at home. Pitt was an expert strategist and conducted the war with vigor. The French fleet was defeated off the coast of Portugal, the English East India Company triumphed over its French counterpart in Bengal and elsewhere, and British and colonial troops in North America captured Fort Duquesne (on the site of present-day Pittsburgh, Pennsylvania), Quйbec, and Montrйal. Although Pitt was forced from office in 1761 and the British negotiated separately from Prussia, the Treaty of Paris (1763) was a diplomatic triumph. All French claims to Canada and to lands east of the Mississippi River were ceded to Britain, as were most French claims to India. Spain, which had entered the war on the French side in 1762, ceded Florida. The Treaty of Paris established Britain’s 18th-century empire at its height.

Population Growth, Urbanization, and Industrialization

During the first half of the 18th century, the population of Great Britain increased by less than 15 percent. Between 1751 and 1801, the year of the first official census, the number rose by one-half to 16 million, and between 1801 and 1851, the population grew by more than two-thirds to 27 million. The reasons include a decline of deaths from infectious diseases, especially smallpox; an improved diet made possible by more efficient farming practices and the large-scale use of the potato; and earlier marriages and larger families, especially in those areas where new industries were starting up. A quickening of economic change was noticeable by the 1780s, when James Watt perfected the steam engine as a new source of power. New inventions mechanized the spinning and weaving of imported cotton. Between 1760 and 1830 the production of cotton textiles increased twelvefold, making the product Britain’s leading export. At the same time, other inventions comparably raised the production of iron, and the amount of coal mined increased fourfold. By 1830 this Industrial Revolution had turned Britain into the “workshop of the world.”

The towns that spread across northwestern England, lowland Scotland, and southern Wales accustomed a generation of workers to factory life. The advantages were more regular hours, higher wages than those received by handicraft workers or farm laborers, and less dependence on human muscle power; many machines could be operated by women and children. The disadvantages included the devaluation of old artisan skills, a new emphasis on discipline and punctuality, and a less personal relationship between employer and employee. For several decades also, such civic amenities as water and sewage systems did not keep pace with the growth of population. London remained Britain’s largest city, a center of commerce, shipping, justice, and administration more than of industry. Its population, estimated at 600,000 in 1701, had grown to 950,000 by 1801, and to 2.5 million by 1851, making it the largest city in the world. By then, Britain had become the first large nation to have more urban than rural inhabitants.

The Early Years of King George III

In 1760, the aged George II was succeeded by his 22-year-old grandson, George III. The new British-born king had a deep sense of moral duty and tried to play a direct role in governing his country. To this end he appointed men he trusted, such as his onetime Scottish tutor, Lord Bute, who became prime minister in 1762. Bute’s ministry was not a success, however, and four short-lived ministries followed until 1770, when George found, in Lord North, a leader pleasing both to him and to the majority of Parliament.

The American Revolution

The fears expressed by Wilkes’s supporters confirmed the more radical American colonial leaders in their suspicion of the British government. Long accustomed to a considerable degree of self-government and freed, after 1763, from the French danger, they resented the attempts by successive British ministries to make them pay a share of the cost of imperial defense in the form of assorted taxes and duties. They also resented British attempts to enforce mercantilistic regulations and to treat colonial legislatures as secondary to the government in London. American resistance led in due course to the calling of the First Continental Congress in 1774 and the commencement of hostilities the following year. Although parliamentary critics such as Edmund Burke continued to urge conciliation, the king and Lord North felt the rebellious colonists had to be brought to their senses.

British governmental authority in the 13 colonies collapsed in 1775. Although British forces were able to occupy first Boston and later New York City and Philadelphia, the Americans did not give up. After the defeat of General John Burgoyne at Saratoga in 1777, the civil war within the British Empire became an international one. First the French (1778), then the Spanish (1779), and the Dutch (1780) joined the anti-British side, while other powers formed a League of Armed Neutrality. For the first time in more than a century, the British were diplomatically isolated. After General Charles Cornwallis’s surrender at Yorktown in 1781, opposition at home to the frustrations and high taxation brought on by the American war compelled Lord North to resign and his successors to sign a new Treaty of Paris in 1783. The 13 colonies were recognized as independent states and were granted all British territory south of the Great Lakes. Florida and Minorca were ceded to Spain and some West Indian islands and African ports to France.
