How Karl Marx responded to the 1848 revolutions

At the outbreak of revolution in February, Marx lived in Brussels under police watch.

On 4 March 1848, shortly after the French monarchy collapsed, Belgian authorities expelled him for his known connections to radical politics.

He arrived in Paris within days, where the revolutionary government had already declared the Second Republic and figures such as Alphonse de Lamartine had assumed prominent roles.

By April, he had settled in Cologne to assist with the German uprisings and had begun preparations for a revolutionary newspaper.

On 1 June 1848, he launched the Neue Rheinische Zeitung, which he intended to use as a revolutionary newspaper that openly backed change rather than a neutral publication. 

To Marx, the unrest confirmed the tensions he had long identified between the emerging industrial proletariat and the ruling classes of Europe.

He believed that aristocrats and the bourgeoisie would soon clash over political control, and that the working class must intervene as a separate force rather than align with either side.

Through his editorials, he rejected liberal reform as a trap, since it preserved the structures of exploitation under a new political vocabulary. 

From the start, he denounced liberal politicians who retreated from confrontation once monarchs offered limited concessions.

As a result, he urged workers to demand full suffrage and to create their own armed militias.

He also called on them to seize the estates of the aristocracy rather than beg for inclusion in a reformed monarchy, since he saw such appeals as capitulation.

Marx saw the early stage of revolution as a battlefield in which compromise ensured defeat.

As he emphasised the need for worker-led organisations and political clarity, he set himself apart from other radical democrats who still viewed constitutional change as a viable path to justice. 

Within the newsroom of the Neue Rheinische Zeitung, published in Cologne, Marx used his control of editorial content to direct political debate.

Alongside Frederick Engels, he published the paper daily between June 1848 and May 1849.

It attacked monarchy and criticised liberal cowardice. At the same time, the paper supported armed resistance as a necessary response to betrayal.

Its tone clearly did not invite negotiation or reconciliation. Rather, it aimed to expose the power structures that concealed themselves behind promises of progress. 

Each issue focused on current events and it also linked them to Marx’s developing view of class struggle.

For example, he praised the June Days Uprising in Paris, which took place from 23 to 26 June 1848, as proof that the French Republic had turned against the very workers who had defended it in February, rather than treating it as a tragic loss.

He described the executions of insurgents under General Cavaignac as confirmation that bourgeois democracy would often resort to violence when property faced real threat.

Marx presented these events as part of a wider pattern in which capitalists used revolutionary enthusiasm to remove feudal obstacles, only to suppress those who wanted deeper change. 

By October, his writing targeted monarchist forces and also liberal assemblies across the German Confederation.

According to Marx, their refusal to protect civil rights or support worker demands showed that their loyalty remained with commercial interests rather than popular justice.

Despite repeated warnings from Prussian censors, Marx increased the paper’s readiness to support open struggle.

By early 1849, counter-revolutionary forces had regained control across the German states.

Prussian troops occupied rebellious cities and arrested dissidents, and then they dismantled local democratic councils.

In response to Marx’s support for the May Uprising in Dresden (3–9 May 1849) and his endorsement of similar actions in the Palatinate during late May and June, authorities revoked his residency.

Before leaving, he published a final edition of the Neue Rheinische Zeitung, dated 19 May 1849, and printed entirely in red ink.

He filled the issue with fierce attacks on reaction and with praise for worker resistance, and he added a warning that state violence would provoke future upheaval. 

After expulsion from Prussia, Marx returned briefly to Paris. However, under pressure from conservative elements within the new French Republic, officials expelled him again.

By August 1849, he had reached London, where he entered permanent exile. From there, he continued to write, though the collapse of revolutionary activity across Europe had closed the window for immediate action.

During this period of defeat, Marx turned his attention to theoretical work and he tried to explain why the revolutions had failed and how future efforts might succeed where those of 1848 had not. 

His analysis began with the role of the middle class, where he concluded that its fear of the working class made it an unreliable ally and that, once its economic interests came under threat, it would usually align with old elites.

In his view, liberal politicians did not lack courage but operated from a position that required them to maintain order and protect capital.

Therefore, revolution could not rely on shared goals between classes whose interests completely clashed.

Marx saw figures such as Heinrich von Gagern, president of the Frankfurt Parliament, as examples of liberals who abandoned popular demands to preserve property and monarchy.

During the early 1850s, Marx published a series of works that traced the revolution’s course and exposed its weaknesses.

In The Class Struggles in France, 1848–1850, he described how working-class energy had been taken over and used by the very governments that now imprisoned or exiled those who had made revolution possible.

He identified each stage of betrayal, from the early refusal to introduce economic reforms to the eventual suppression of the June Uprising, as part of a wider logic that governed class society. 

In The Eighteenth Brumaire of Louis Bonaparte, completed in 1852, Marx turned his attention to France.

He analysed how Louis-Napoleon exploited confusion and fear among his opponents, and how he used the self-interest of political elites to dissolve the National Assembly and declare himself Emperor.

The title referred to 9 November 1799, the date Napoleon Bonaparte had seized power in a coup that replaced the French Republic with military dictatorship.

According to Marx, the bourgeoisie allowed this outcome because dictatorship preserved their property and crushed worker unrest, rather than because they were deceived.

He ridiculed liberal hopes that history would follow a path of constant progress and insisted that revolution had to be organised rather than hoped for. 

As he reflected on the years since 1848, Marx abandoned earlier expectations that economic crisis alone would produce revolution.

He now placed greater importance on political leadership and on the formation of class consciousness, and he increasingly stressed the construction of a movement that was prepared to endure both defeat and delay.

In exile, he sharpened his writing and expanded his collaboration with Engels, and he began laying the basic foundations for his ideas for a new kind of revolutionary organisation.

In 1850, they reorganised the Communist League and issued an address that called for working-class independence from the petty bourgeoisie.

The events of 1848 had exposed the weakness of monarchy and also showed that liberal revolution could rarely be trusted.

Marx concluded that the working class could not afford to place its demands below the goals to the goals of another class, no matter how progressive those goals appeared.

He insisted that any future revolution must centre on proletarian control as a principle that defined both methods and outcomes, rather than as a simple slogan. 

In the years that followed, he worked to build the Communist League and he later founded the International Workingmen’s Association in London on 28 September 1864, and these efforts reflected this strategic shift.

He rejected nationalist movements that prioritised statehood over social transformation and condemned alliances with reformers who would abandon the poor once property came under threat.

For Marx, the lessons of 1848 demanded clarity. Revolution required preparation and demanded international coordination.

Above all, it demanded independence from classes that often saw equality as a danger rather than a goal. 

When he turned defeat into analysis and analysis into strategy, Marx transformed the failure of the 1848 revolutions into a foundation for future struggle.

He had entered the year with hope that revolution might erupt across Europe. He left it convinced that revolution must be made with care and with firm resolve, guided by the knowledge that betrayal could come from those who feared the world they claimed to build.
