The revolutions of 1848 are unusual in this book for their sheer simultaneity. Beginning in Sicily in January, spreading to Paris by February, and then within weeks to Vienna, Berlin, Budapest, Prague, Milan, Venice and dozens of smaller German and Italian states, nearly every major European capital except London and Saint Petersburg experienced serious revolutionary upheaval within a few months of each other.
No single conspiracy or organisation coordinated this. Communication across borders was far too slow and unreliable for that. Instead, similar underlying pressures, built up over decades under the Vienna settlement examined in the previous chapter, produced similar reactions once the first spark, in Paris, showed that a monarch could actually be toppled by a determined crowd.
The immediate trigger in France was almost mundane: the king's government banned a series of political banquets that opposition liberals had been using to campaign, in the absence of any legal right to hold political meetings, for expanded suffrage. When the government banned the last of these banquets in February 1848, protests turned into barricades, the army refused to fire on the crowds with full commitment, and King Louis Philippe abdicated within days, fleeing to England disguised, in a detail that recalled Louis the Sixteenth's own failed flight, under an assumed name.
The demands varied by country, but three overlapping strands ran through nearly all of them.
Liberal constitutionalism: written constitutions, elected parliaments with real power, freedom of the press and of assembly, an end to arbitrary arrest and censorship, the basic package examined already in chapters thirty one and thirty six, still unrealised across most of continental Europe.
National unification or independence: German nationalists wanted a unified Germany rather than the loose confederation of thirty-nine states left by Vienna. Italian nationalists wanted an Italy free of Austrian control and, ideally, unified. Hungarians wanted autonomy or independence from Habsburg Austria. Czechs, Poles and other peoples within the multinational Austrian and German lands wanted recognition of their own national identity, often in direct tension with the German or Hungarian nationalists who wanted to absorb or dominate them.
Women played a real, though largely uncredited, part in these movements as well. In Paris, women formed political clubs, published newspapers arguing for their own political rights alongside the broader republican cause, and petitioned the new government for suffrage, only to be excluded entirely when the provisional government extended the vote to all adult men and stopped there. The women's clubs were banned outright within months, one of the earliest concrete reversals of the revolution's own stated universal principles, and a pattern uncomfortably familiar from the previous chapters on 1789.
And, in France specifically, a stronger social and economic dimension than elsewhere: workers in Paris, suffering from an economic downturn and rising unemployment, wanted not merely political liberty but the right to work itself, and the provisional government briefly established national workshops guaranteeing employment, a genuinely radical experiment that alarmed propertied liberals as much as it excited the workers who benefited from it.
The most ambitious single project of 1848 was the Frankfurt Parliament, an assembly of delegates elected from across the German states, convening from May 1848 to draft a constitution for a unified German nation, the first genuinely national, elected, deliberative body in German history.
It faced, from the start, a question it could not resolve: what Germany actually was. A greater German solution would have included Austria and its many non-German subject peoples, an option Austria's own multinational structure made essentially unworkable without dissolving the Habsburg monarchy itself. A smaller German solution would have excluded Austria and centred a unified Germany on Prussia instead.
After months of debate the parliament settled on the smaller solution and, in April 1849, offered the imperial crown of a unified Germany to the King of Prussia, Frederick William the Fourth. He refused it, dismissing the offer as a crown from the gutter, picked up by revolutionaries and commoners rather than granted by the legitimate authority of Germany's princes, a rejection that reflected his own conservative belief that only Germany's ruling houses, not an elected assembly, had the right to confer such a title.
Without Prussian backing, the Frankfurt Parliament's constitution had no means of enforcement. It dissolved within months, its more radical remnants suppressed by force. German unification would come, a generation later, examined in chapter forty three, but through Prussian military power under Bismarck rather than through the liberal, elected process the Frankfurt delegates had attempted.
Austria faced the most severe crisis of any major power, because its empire was not merely dealing with liberal demands for constitutional government but with simultaneous national uprisings among Hungarians, Czechs, Italians and others, each pulling the multinational state in a different direction.
In March 1848, revolution in Vienna itself forced Metternich, the very architect of the post-1815 order examined in the previous chapter, to flee the city in disguise, ending his forty-year tenure in a single week. The Habsburg court briefly fled the capital as well.
In Hungary, a national government under Lajos Kossuth declared far-reaching autonomy and, eventually, full independence from Habsburg rule, while simultaneously refusing similar national recognition to the Croatian, Serbian and Romanian populations within Hungary's own borders, a contradiction that fatally split the Hungarian revolution's own base of support and gave the Habsburgs an opening.
The Austrian monarchy survived, ultimately, by playing its subject nationalities against each other and by calling in outside help. Croatian forces, resentful of Hungarian nationalism's refusal to extend to them the same rights it claimed for itself, fought against the Hungarian revolution on the Habsburgs' behalf. And when Austrian forces alone proved unable to fully suppress the Hungarian uprising, the new young Emperor Franz Joseph turned to Russia, whose Tsar Nicholas the First, the self-appointed guardian of monarchical legitimacy across Europe, sent an army that crushed the last Hungarian resistance in August 1849.
Several factors, combined rather than any single one, explain the near-universal collapse of these revolutions within about eighteen months.
The revolutionary coalitions were themselves internally divided. Liberal constitutionalists wanting moderate reform, radical democrats wanting a full republic, nationalists wanting unification or independence, and socialist workers wanting economic change, had cooperated only briefly against the old order, and once that order wavered, their competing and often contradictory goals pulled the revolutions apart from within, exactly as the Hungarian-Croatian split illustrated.
The armies, in nearly every case, remained loyal to the monarchies rather than joining the revolutions, in contrast to what had happened at key moments in France in 1789 and again briefly in February 1848 itself. Once monarchs regained their nerve and their generals' loyalty, military force reversed what crowds and barricades had won.
And the great powers that might have supported liberal change instead, in the Austrian and Hungarian case most starkly, actively cooperated to suppress it, with conservative Russia intervening explicitly to preserve monarchical order elsewhere, exactly the kind of cross-border reactionary solidarity the Holy Alliance of the previous chapter had envisioned, even if it had never worked quite so effectively before.
Italy's experience of 1848 deserves separate attention, because it directly rehearsed the unification that would succeed just over a decade later, examined in chapter forty three.
Uprisings broke out across the Italian peninsula against both Austrian control in the north and the conservative rule of various Italian princes and the Pope himself in the centre and south. The King of Piedmont-Sardinia, Charles Albert, declared war on Austria in an attempt to lead Italian unification under his own crown, and briefly won real popular enthusiasm across several Italian states for the cause.
It failed militarily. Austrian forces under an experienced elderly general, Radetzky, defeated the Piedmontese army decisively, and Charles Albert abdicated in favour of his son Victor Emmanuel. In Rome, revolutionaries briefly declared a republic and forced the Pope to flee the city, only for French troops, sent by the new French president Louis Napoleon Bonaparte, nephew of the earlier emperor, to restore papal rule by force in 1849, an intervention that entangled French politics with the Italian question for decades afterward.
What survived from this failure was the House of Savoy's claim to Italian leadership, and the young Victor Emmanuel who inherited it. When unification did succeed in the following decades, it happened substantially because Piedmont-Sardinia had established itself, through this failed attempt, as the Italian state with the clearest nationalist credentials and the readiest monarchy to lead a second try.
Judged by their own immediate stated goals, nearly every revolution of 1848 failed. Constitutions were suspended or revoked, national unification projects collapsed, and many of the revolutionary leaders were imprisoned, executed, or fled into permanent exile, a substantial number of them to the United States and Britain, where several went on to influence the politics of their adopted countries considerably.
But some changes proved harder to reverse than the crowned heads who reversed the rest might have wished. Serfdom, already weakening across much of central Europe, was formally abolished in the Austrian empire in 1848 and never restored. Many states retained some form of constitution or parliament afterward, even if stripped of much of their power, planting an institutional seed that would matter later in the century.
And the failed revolutions taught a durable lesson to the political generation that lived through them, one that shaped the rest of the century: that liberal idealism and popular enthusiasm alone, without control of an army and without a realistic strategy for holding power once won, could not overturn an entrenched order. That lesson was absorbed with particular clarity by a young Otto von Bismarck, who watched the Prussian and German revolutions of 1848 from a conservative vantage point he never abandoned, and who would apply the opposite lesson, that unification and reform required blood and iron rather than parliamentary votes, when his own turn came, examined directly in chapter forty three.
Firm: the sequence of uprisings, the Frankfurt Parliament's proceedings, and the military campaigns that suppressed the Hungarian and Italian revolutions, all extensively documented in parliamentary records, military archives and contemporary press across many countries.
Soft: the precise scale of casualties across so many simultaneous and geographically scattered conflicts, which varied enormously by location and were recorded with very different degrees of care.
Contested: whether 1848 should be remembered mainly as a failure, given how quickly nearly every revolutionary government was overturned, or as a genuine turning point, given how much of the century's later political agenda, national unification, constitutional government, the end of serfdom, had been rehearsed and partly achieved even in defeat. A once-common historical judgment held that 1848 was the turning point at which German history failed to turn, implying a fateful missed opportunity for liberal development. More recent historians have questioned how inevitable any different outcome really was, given the divisions and weaknesses the revolutions displayed on their own terms.
A note on scope. This chapter has necessarily compressed dozens of distinct national uprisings, each with its own local causes, personalities and outcomes, into a single continental narrative. That compression risks flattening real differences, between, for instance, the socially radical Parisian revolution and the more narrowly nationalist Hungarian one, and a fuller treatment of any single country's 1848 would fill a book on its own.
