May 21
French Troops Enter Paris to Crush the Commune
Government troops loyal to the Third Republic entered Paris on May 21, 1871, launching a week-long assault that crushed the radical experiment of the Paris Commune.
Summary
Following France's defeat in the Franco-Prussian War, the Paris Commune had governed the city since March 18, 1871, implementing radical reforms including separation of church and state and workers' self-management amid the establishment of the Third Republic. On May 21, national forces under Adolphe Thiers and Marshal MacMahon breached the city walls and began the semaine sanglante, or Bloody Week. Street-by-street fighting ensued as government troops systematically retook barricades and neighborhoods held by Communard National Guard units. The assault continued through the end of May, resulting in an estimated 10,000 to 20,000 Communard deaths from battle and summary executions, alongside the Commune's own killings of hostages including the Archbishop of Paris.
Context
France's humiliating defeat in the Franco-Prussian War of 1870–1871 had toppled the Second Empire and led to the proclamation of the Third Republic in September 1870. The new national government, headed by Adolphe Thiers after elections in February 1871, faced deep divisions: rural provinces leaned conservative and monarchist, while Paris remained a center of republican and working-class radicalism. The city's National Guard, swelled by workers who had endured the Prussian siege, grew increasingly defiant of Versailles authority.
What Happened
On the afternoon of May 21, troops under Marshal Patrice de MacMahon slipped through an undefended gate at the Point du Jour and advanced into western Paris. Communard defenders, organized in National Guard units, responded by erecting barricades across neighborhoods and fighting building-to-building as government forces methodically cleared streets. The fighting intensified over the following days, with key clashes around Montmartre, the Place de la Concorde, and the eastern arrondissements; by May 28 the last pockets of resistance at Père Lachaise cemetery had been overrun.
Aftermath
The Commune's defeat triggered immediate reprisals, including summary executions and the arrest of tens of thousands of suspected supporters. The Versailles government also faced the Commune's own final acts of violence, such as the execution of hostages that included Archbishop Georges Darboy. Military courts later tried more than 15,000 people, resulting in deportations to New Caledonia and other penalties, while thousands more fled into exile.
Legacy
The suppression ended the Commune's brief radical governance and reinforced the conservative orientation of the early Third Republic for years to come. Its memory profoundly shaped European socialist thought; Karl Marx and Friedrich Engels cited it as a practical example of proletarian power, influencing later revolutionary theory. Periodic amnesties, culminating in 1880, allowed many survivors to return and eventually participate in French politics, keeping the events alive in public debate.
Why It Matters
The brutal suppression ended the Commune's brief experiment in radical self-governance and solidified the conservative Third Republic's control, shaping French politics for decades. It provided a powerful example for later socialist and communist thinkers, notably influencing Karl Marx and Friedrich Engels' concept of the dictatorship of the proletariat. The events also prompted mass exiles, trials, and eventual amnesties that affected French society into the 1880s.
