Repeal of the Corn Laws (1846): Free Trade and Peel's Fall

The repeal of the Corn Laws in 1846 abolished the tariffs that had protected British farmers and landowners from imported grain since the Napoleonic Wars. It was the result of a long campaign by the Anti-Corn Law League and of a crisis brought on by the potato blight in Ireland. Prime Minister Robert Peel carried repeal against the majority of his own Conservative Party, which split as a result, and Britain became the world’s leading champion of free trade.

Background: what the Corn Laws were

In Britain “corn” meant all cereal grains, especially wheat. Laws regulating the grain trade were centuries old, but the most important was the Importation Act of 1815, passed just after the Napoleonic Wars. It banned the import of foreign wheat until the domestic price reached 80 shillings per quarter (a measure of about 480 lb, or 218 kg), a very high level.

The law protected farmers and above all the landowning class, which dominated both Houses of Parliament. Critics argued that it kept bread dear for working people, forced up wages that manufacturers had to pay and invited other countries to shut out British goods. Discontent over food prices contributed to the unrest of the period, including the meeting that ended in the Peterloo Massacre in 1819. The rigid ban was replaced by a sliding scale of duties in 1828, which Peel lowered in 1842, but the principle of protection remained.

The Anti-Corn Law League

The decisive pressure came from the Anti-Corn Law League, which grew out of an association founded in Manchester in 1838 and was organised as a national League in 1839. Its leaders were Richard Cobden, a calico printer, and John Bright, a cotton spinner from Rochdale. Both were nonconformists from the new industrial middle class, and both entered Parliament, Cobden in 1841 and Bright in 1843.

The League was one of the first modern pressure groups. It used the new penny post, introduced in 1840, and the expanding railways to distribute millions of pamphlets, sent lecturers across the country, held mass meetings, raised large funds from manufacturers and built the Free Trade Hall in Manchester. It also bought up qualifying property so that free-trade supporters could vote in county elections. Its arguments combined economics, morality and class politics: cheap food, more trade, international peace and an attack on aristocratic privilege. Supporters drew on the ideas of economists such as Adam Smith and David Ricardo, who had argued that protection raised the price of food, swelled landlords’ rents and held back industry. Opponents replied that home-grown grain was vital for national security, that farm labourers’ jobs depended on protection, and that the League’s leaders simply wanted cheaper bread so that they could pay lower wages.

The League competed for working-class support with the Chartist movement, which often distrusted it as a manufacturers’ campaign to cut wages.

The crisis of 1845

Peel had moved steadily towards free trade during his government of 1841–1846, reducing many tariffs and reintroducing income tax in 1842 to replace lost revenue. He held back from repealing the Corn Laws, however, because his party relied on landowners.

In autumn 1845 potato blight struck Ireland, threatening the start of what became the Great Irish Famine. Peel concluded that the ports must be opened to food and that once opened they could not be closed again. In November the Whig leader Lord John Russell publicly came out for repeal in his “Edinburgh Letter”. When Peel’s cabinet divided, he resigned in December 1845, but Russell failed to form a government and Peel returned to office within weeks, determined to act.

Repeal passes

Peel announced his proposals in the Commons on 27 January 1846. Duties on foreign wheat would be reduced over three years and then fixed at a nominal 1 shilling per quarter from 1 February 1849, with other agricultural tariffs also cut.

The protectionist wing of the Conservative Party, led in debate by Benjamin Disraeli and Lord George Bentinck, attacked Peel with great bitterness for betraying the party that had elected him. The bill passed its third reading in the Commons on 15 May 1846 by 327 votes to 229, but only around a third of Conservative MPs voted for it; the majority came from Whigs, Radicals and Irish members. The House of Lords, persuaded partly by the Duke of Wellington, passed it on 25 June 1846, and it received royal assent the next day.

Peel’s fall and the Conservative split

On the same night that the Lords passed repeal, the protectionists took their revenge. They voted with the Whigs and Irish members to defeat the government’s Irish coercion bill by 292 votes to 219. Peel resigned on 29 June 1846. In his resignation speech he gave the credit for repeal to Richard Cobden.

The Conservative Party broke in two. The protectionist majority, led by Lord Stanley (later Earl of Derby) and Disraeli, kept the Conservative name but did not win a Commons majority until 1874. The free-trade “Peelites”, including William Gladstone, Lord Aberdeen and Sir James Graham, drifted towards the Whigs and Radicals and helped create the Liberal Party in 1859. Peel himself died in 1850 after a riding accident.

Consequences

Repeal did not cause the collapse in farming that its opponents feared. British agriculture enjoyed a prosperous period of “high farming” in the 1850s and 1860s, helped by rising demand from a growing population. The real fall in grain prices came from the 1870s, when railways and steamships brought cheap grain from the American prairies and elsewhere, contributing to a long agricultural depression.

Repeal was followed by the abolition of the Navigation Acts in 1849 and further tariff cuts, especially in Gladstone’s budgets of the 1850s and 1860s. Free trade became a central part of British identity for decades, and the Cobden–Chevalier Treaty of 1860 with France extended it into Europe. Protection did not return in a serious way until the 1930s.

Legacy

The Anti-Corn Law League became a model for later single-issue campaigns, showing how organisation, publicity and money could change national policy. Peel’s decision is still cited as a classic example of a leader putting what he saw as the national interest before party unity, at great personal cost. Historians continue to debate how much repeal owed to the League, to economic ideas, to the Irish crisis and to Peel’s own convictions.

Why it matters

The repeal of the Corn Laws marked the moment when Britain’s industrial and commercial interests overcame the political power of landed aristocracy. It made free trade national policy for almost a century, reshaped the party system and remains a reference point in arguments about trade, food prices and political leadership.
