Conservatism did dominate the European political agenda through the mid-1820s. Major governments, even in Britain, used police agents to ferret out agitators. The prestige of the Roman Catholic church soared in France and elsewhere. Europe’s conservative leader was Prince von Metternich, chief minister of the Habsburg monarchy. Metternich realized the fragility of Habsburg rule, not only wedded to church and monarchy but also, as a polyglot combination of German, Hungarian, and Slavic peoples, vulnerable to any nationalist sentiment. He sedulously avoided significant change in his own lands and encouraged the international status quo as well. He sponsored congresses at several points through the early 1820s to discuss intervention against political unrest. He was particularly eager to promote conservatism in the German states and in Italy, where Austrian administration of northern provinces gave his regime a new stake.

Nevertheless, in 1820 revolutionary agitation broke out in fringe areas. Risings in several Italian states were put down. A rebellion in Spain was also suppressed, though only after several years, foreshadowing more than a century of recurrent political instability; the revolution also confirmed Spain’s loss of most of its American colonies, which had first risen during the Napoleonic occupation. A Greek revolution against Ottoman control fared better, for Greek nationalists appealed to European sympathy for a Christian nation struggling against Muslim dominance. With French, British, and Russian backing, Greece finally won its independence in 1829.

Liberal agitation began to revive in Britain, France, and the Low Countries by the mid-1820s. Liberals wanted stronger parliaments and wider protection of individual rights. They also sought a vote for the propertied classes. They wanted commercial legislation that would favour business growth, which in Britain meant attacking Corn Law tariffs that protected landlord interests and kept food prices (and so wages) artificially high. Belgian liberals also had a nationalist grievance, for the Treaty of Vienna had placed their country under Dutch rule.

Liberal concerns fueled a new round of revolution in 1830, sparked by a new uprising in Paris. The French monarchy had tightened regulation of the press and of university professors, producing classic liberal issues. Artisans, eager for more political rights, also rose widely against economic hardship and the principles of the new commercial economy. This combination chased the Bourbon king, producing a new and slightly more liberal monarchy, an expanded middle-class voting system, and some transient protections for freedom of the press; the new regime also cut back the influence of the church. Revolution spread to some German and Italian states and also to Belgium, where after several years an independent nation with a liberal monarchy was proclaimed. Britain was spared outright revolution, but massive agitation forced a Reform Bill in 1832 that effectively enfranchised all middle-class males and set the framework for additional liberal legislation, including repeal of the Corn Laws and municipal government reform, during the next decade.

Europe was now divided between a liberal west and a conservative centre and east. Russia, indeed, seemed largely exempt from the political currents swirling in the rest of the continent, partly because of the absence of significant social and economic change. A revolt by some liberal-minded army officers in 1825 (the Decembrist revolt) was put down with ease, and a new tsar, Nicholas I, installed a more rigorous system of political police and censorship. Nationalist revolt in Poland, a part of the 1830 movement, was suppressed with great force. Russian diplomatic interests continued to follow largely traditional lines, with recurrent warfare with the Ottoman Empire in an effort to gain territory to the south. Only after 1850 did the Russian regime seriously rethink its adamantly conservative stance.

This pattern could not prevail elsewhere in Europe. Scandinavian governments moved toward increasing liberalism by expanding the power of parliaments, a development that was completed in the late 1840s; the Dutch monarchy did the same. Elsewhere, the next major step resulted once again from a series of revolutions in 1848, which proved to be western Europe’s final revolutionary round.
