Pressure from below also reshaped politics in Great Britain, but through a process of gradual reform rather than revolution. Eighteenth-century Britain had been remarkably stable. The landowning aristocracy dominated society, but that class was neither closed nor rigidly defined. Moreover, common people enjoyed limited civil rights. Yet the constitutional monarchy was hardly democratic. With only about 8 percent of the population allowed to vote, the British Parliament, easily manipulated by the king, remained in the hands of the upper classes.

In 1815, open conflict between the ruling class and laborers emerged when the aristocracy rammed far-reaching changes in the Corn Laws through Parliament. Britain had been unable to import cheap grain from eastern Europe during the war years, leading to high prices and large profits for the landed aristocracy. With the war over, grain (which the British generically called “corn”) could be imported again, allowing the price of wheat and bread to go down and benefiting almost everyone — except aristocratic landlords. The new Corn Laws prohibited the importation of foreign grain unless the price at home rose to improbable levels.

The change in the Corn Laws, coming as it did at a time of widespread unemployment and postwar economic distress, triggered protests and demonstrations by urban laborers, who enjoyed the support of radical intellectuals. In 1817, the Tory government, controlled completely by the landed aristocracy, responded by temporarily suspending the traditional rights of peaceable assembly and habeas corpus, which gives a person under arrest the right to a trial. Two years later, Parliament passed the infamous Six Acts, which, among other things, placed controls on a heavily taxed press and practically eliminated all mass meetings. These acts followed an enormous but orderly protest, at Saint Peter’s Fields in Manchester, which was savagely broken up by armed cavalry. Nicknamed the Battle of Peterloo, in scornful reference to the British victory at Waterloo, this incident demonstrated the government’s determination to repress dissenters.

In the 1820s, a less frightened Tory government moved in the direction of better urban administration, greater economic liberalism, civil equality for Catholics, and limited imports of foreign grain. These actions encouraged the middle classes to press on for reform of Parliament so they could have a larger say in government.

The Whig Party, though led like the Tories by great aristocrats, had by tradition been more responsive to middle-class commercial and manufacturing interests. In 1830, a Whig ministry introduced “an act to amend the representation of the people of England and Wales.” After a series of setbacks, the Whigs’ Reform Bill of 1832 was propelled into law by a mighty surge of popular support.

Significantly, the bill moved British politics in a democratic direction and allowed the House of Commons to emerge as the all-important legislative body, at the expense of the aristocrat-dominated House of Lords. The new industrial areas of the country gained representation in the Commons, and many old “rotten boroughs” — electoral districts that had very few voters and that the landed aristocracy had bought and sold — were eliminated. The number of voters increased by about 50 percent, to include about 12 percent of adult men in Britain and Ireland. Comfortable middle-class groups in the urban population, as well as some substantial farmers who leased their land, received the vote.

The “People’s Charter” of 1838 and the Chartist movement it inspired pressed British elites for yet more radical reform (see "The Early British Labor Movement" in Chapter 20). Inspired by the economic distress of the working class in the 1830s and 1840s, the Chartists demanded universal male (but not female) suffrage. Hundreds of thousands of people signed gigantic petitions calling on Parliament to grant all men the right to vote, first in 1839, again in 1842, and yet again in 1848. Parliament rejected all three petitions. In the short run, the working poor failed with their Chartist demands, but they learned a valuable lesson in mass politics.

While calling for universal male suffrage, many working-class people joined with middle-class manufacturers in the Anti–Corn Law League, founded in Manchester in 1839. Mass participation made possible a popular crusade led by fighting liberals. When Ireland’s potato crop failed in 1845 and famine prices for food seemed likely in England, Tory prime minister Robert Peel joined with the Whigs and a minority of his own party to repeal the Corn Laws in 1846 and allow free imports of grain. England escaped famine. Thereafter the liberal doctrine of free trade became almost sacred dogma in Great Britain.

The following year, the Tories passed a bill designed to help the working classes, but in a different way. The Ten Hours Act of 1847 limited the workday for women and young people in factories to ten hours. In competition with the middle class for the support of the working class, Tory legislators continued to support legislation regulating factory conditions. This competition between a still-powerful aristocracy and a strong middle class was a crucial factor in Great Britain’s peaceful political evolution. The working classes could make temporary alliances with either competitor to better their own conditions.
