January 23, 1844 - April 1, 1912
Paul Brousse was a French socialist, leader of the possibilistes
group. He was active in the Jura
Federation, a section of the International Working Men's Association (IWMA), from the northwestern part of Switzerland and the Alsace. He helped edit the Bulletin
de la Fédération Jurassienne, along with anarchist Peter Kropotkin. He was in contact with Gustave Brocher between 1877 and 1880, who became anarchist under Brousse's influence. Paul Brousse edited two newspapers, one in French and another in German. He helped James Guillaume publish
Paul Brousse studied medicine and travelled to Barcelona in his youth. He then joined the IWMA and participated
to the Geneva Congress in September 1873, seeing anarchism as the only possible social organization. On March 18, 1877, he took part in Bern in a demonstration in remembrance of the 1871 Paris Commune, which ended in riots with the police. Paul Brousse was subsequently condemned to one month
of prison. On April 15, 1879, he is again sentenced to two months of prison, and then expulsed from Switzerland, for having published an article in L'Avant-Garde which
legitimized the propaganda
of the deed attempts of Giovanni Passannante, Juan Oliva Moncasi, Max Hödel and Karl Nobiling. Paul Brousse then returned to France in 1880 and progressively became more reformist. He began to take part in the French Workers' Party (POF) and then, after a scission, to
the Federation of the Socialist Workers of France (FTSF), which became known as the "possibilists". He voted at the August 1886 international congress in London along with Jules Guesde for the expulsion of the "anti-authoritarian socialists", as were known the anarchists.
The possibilists then joined Jean
Jaurès's French Socialist Party in 1902, which fused with others movements in 1905 to create the French Section of the Workers' International (SFIO).
