The Six Acts of 1819, associated with Henry Addington, Viscount Sidmouth, the home secretary, were designed to reduce disturbances and to check the extension of radical propaganda and organization. They provoked sharp criticism even from the more moderate Whigs as well as from the radicals, and they did not dispel the fear and suspicion that seemed to be threatening the stability of the whole social order. There was a revival of confidence after 1821, as economic conditions improved and the government itself embarked on a program of economic reform. Even after the collapse of the economic boom of 1824–25, no attempt was made to return to policies of repression.
There was a change of tone, if not of principle, in foreign policy, as in home affairs, after the suicide of the foreign secretary, Robert Stewart, Viscount Castlereagh. Castlereagh, who had represented Britain at the Congress of Vienna in 1815, pursued a policy of nonintervention, refusing to follow up the peace settlement he had signed, which entailed provisions for converting the Quadruple Alliance of the victorious wartime allies into an instrument of police action to suppress liberalism and nationalism anywhere in Europe. His successor at the Foreign Office, George Canning, propounded British objectives with a strong appeal to British public opinion and emphasized differences between British viewpoints and interests and those of the European great powers more than their common interests. In 1824 he recognized the independence of Spain’s American colonies, declaring in a famous phrase that he was calling “the New World into existence to redress the balance of the Old.” In 1826 he used British force to defend constitutional government in Portugal, whereas in the tension-ridden area of the eastern Mediterranean, he supported the cause of Greek independence. His policies and styles were reasserted by Henry John Temple, Viscount Palmerston, who became foreign minister in 1830.
The situation in Ireland heralded the end of one pillar of the old order—namely, legal restrictions on the civil liberties of Roman Catholics. Irish disorders centred, as they had since the Act of Union in 1801, on the issue of Catholic emancipation, a favourite cause of the Whigs, who had been out of power since 1807. During the 18th century, Catholics in England had achieved a measure of unofficial toleration, but in Ireland restrictions against Catholics holding office were still rigorously enforced. In 1823 Daniel O’Connell, a Dublin Roman Catholic lawyer, founded the Catholic Association, the object of which was to give Roman Catholics in Ireland the same political and civil freedoms as Protestants. Employing pioneering techniques of organization, involving the mobilization of the large numbers of the poor and the excluded in great open-air demonstrations, O’Connell introduced a new form of mass politics that galvanized opinion in Ireland while at the same time mobilized radical allies in England. The result was the passing of the Catholic Emancipation Act in 1829.
The death in June 1830 of George IV (whose reign had begun in 1820) heralded the end of another pillar of the old order, the unreformed system of parliamentary representation. In a year of renewed economic distress and of revolution in France, when the political reform issue was being raised again at public meetings in different parts of Britain, Wellington, the military hero of the Napoleonic Wars who had assumed the premiership in 1828, had not made matters easier for himself by expressing complete confidence in the constitution as it stood. In consequence he resigned, and the new king, William IV (1830–37), invited Charles Grey, 2nd Earl Grey, to form a government. Grey’s cabinet was predominantly aristocratic—including Canningites as well as Whigs—but the new prime minister, like most of his colleagues, was committed to introducing a measure of parliamentary reform. For this reason, 1830 marked a real parting of the ways. At last there was a break in the continuity of regime that dated from the victory of William Pitt, the Younger, over Charles James Fox in the 1780s and that had only temporarily been interrupted in 1806–07. Moreover, the new government, aristocratic or not, was the parent of most of the Whig-Liberal administrations of the next 35 years.
