MontmartreMontmartre (UKmɒnˈmɑːrtrə , mɔ̃maʁtʁ) is a large hill in Paris's northern 18th arrondissement. It is high and gives its name to the surrounding district, part of the Right Bank. Montmartre is primarily known for its artistic history, for the white-domed Basilica of the Sacré-Cœur on its summit, and as a nightclub district. The other church on the hill, Saint Pierre de Montmartre, built in 1147, was the church of the prestigious Montmartre Abbey.
Charles FourierFrançois Marie Charles Fourier (ˈfʊrieɪ,_-iər;ʃaʁl fuʁje; 7 April 1772 – 10 October 1837) was a French philosopher, an influential early socialist thinker and one of the founders of utopian socialism. Some of Fourier's social and moral views, held to be radical in his lifetime, have become mainstream thinking in modern society. For instance, Fourier is credited with having originated the word feminism in 1837. Fourier's social views and proposals inspired a whole movement of intentional communities.
BlanquismBlanquism refers to a conception of revolution generally attributed to Louis Auguste Blanqui (1805–1881) that holds that socialist revolution should be carried out by a relatively small group of highly organised and secretive conspirators. Having seized power, the revolutionaries would then use the power of the state to introduce socialism. It is considered a particular sort of "putschism"—that is, the view that political revolution should take the form of a putsch or coup d'état.
Arrondissements of ParisThe City of Paris is divided into twenty arrondissements municipaux, administrative districts, more simply referred to as arrondissements (aʁɔ̃dismɑ̃). These are not to be confused with departmental arrondissements, which subdivide the larger French departments. The number of the arrondissement is indicated by the last two digits in most Parisian postal codes (75001 up to 75020). In addition to their number, each arrondissement also has a name, often for a local monument.
