"The Paris Commune or Fourth French Revolution (French: La Commune de Paris, IPA: [la kmyn d pai]) was a government that briefly ruled Paris from March 18 (more formally, from March 28) to May 28, 1871. In a formal sense, it acted as the local authority, the City council (in French, the "commune"), which exercised power in Paris for two months in the spring of 1871, [and had nothing to do with the much-later Communists.]"--Wikipedia.
