The Paris Commune (Commune de Paris, kɔ.myn də pa.ʁi) was a French revolutionary government that seized power in Paris from 18 March to 28 May 1871.
During the Franco-Prussian War of 1870–71, the French National Guard had defended Paris, and working-class radicalism grew among its soldiers. Following the establishment of the Third Republic in September 1870 (under French chief executive Adolphe Thiers from February 1871) and the complete defeat of the French Army by the Germans by March 1871, soldiers of the National Guard seized control of the city on March 18. They killed two French army generals and refused to accept the authority of the Third Republic, instead attempting to establish an independent government.
The Commune governed Paris for two months, establishing policies that tended toward a progressive, anti-religious system of their own self-styled socialism, which was an eclectic mix of many 19th-century schools. These policies included the separation of church and state, self-policing, the remission of rent, the abolition of child labor, and the right of employees to take over an enterprise deserted by its owner. All Roman Catholic churches and schools were closed. Feminist, socialist, communist, old style social democracy (which was a mix of reformism and revolutionism) and anarchist currents played important roles in the Commune. However, the various Communards had little more than two months to achieve their respective goals.
The national French Army suppressed the Commune at the end of May during La semaine sanglante ("The Bloody Week") beginning on 21 May 1871. The national forces killed in battle or quickly executed between 10,000 and 15,000 Communards, though one unconfirmed estimate from 1876 put the toll as high as 20,000. In its final days, the Commune executed the Archbishop of Paris, Georges Darboy, and about one hundred hostages, mostly gendarmes and priests. 43,522 Communards were taken prisoner, including 1,054 women. More than half were quickly released. Fifteen thousand were tried, 13,500 of whom were found guilty.
