Was a radical socialist and revolutionary government that ruled Paris from 28 March to 28 May 1871. With the defeat of Emperor NapoleonĀ III in September 1870, the second French army collapsed. A hotbed of common radicalism, France’s capital was primarily defended during this time by the often politicized and radical troops of the National Guard rather than regular Army troops. In February 1871 Adolphe Thiers, the new chief executive of the French national government, signed an armistice with Prussia that disarmed the Army but not the National Guard.
