Revolutionary Socialist Workers' Party (France)

The Revolutionary Socialist Workers' Party (French: Parti ouvrier socialiste révolutionnaire, POSR) was a French political party founded by Jean Allemane in 1890 and dissolved in 1901. It is indirectly one of the founding factions of the French Section of the Workers' International (SFIO), founded in 1905.

The POSR was founded by a dissidence from the Federation of the Socialist Workers of France (FTSF) led Allemane. Therefore, the POSR became known as an Allemaniste party. That is, a party which was a strong believer of the primacy of syndicalism in politics and the POSR became a base of future revolutionary syndicalism.

However, next to the working-class socialism of Allemane, an intellectual socialist movement developed within the POSR, led by Lucien Herr, a librarian. This movement's priority was the education of the people. Overall, the POSR was a moderate reformist party, influenced by possibilism which believed that socialism could be achieved though democratic action, such as decentralization and legislative participation.

In 1901, the POSR merged with the FTSF and Independent Socialists to form the French Socialist Party (PSF). The PSF was, along with the Socialist Party of France, in 1905, a founding member of the French Section of the Workers' International (SFIO).
