Uprising of March 18, 1871

The Paris uprising of 18 March 1871 was an insurrection involving elements of the National Guard and sections of the Parisian population, triggered by the attempt of the government led by Adolphe Thiers to reclaim artillery pieces that had been financed by public subscription during the Prussian siege of Paris. The uprising marked the beginning of the Paris Commune, the most significant of the insurrectionary communes that emerged in France in 1870–1871.
