Portuguese Socialist Party

The Portuguese Socialist Party (Portuguese: Partido Socialista Português) is a Portuguese left-wing political party founded in 1875.
At its foundation, under the leadership of José Fontana, the party was influenced by Proudhonism and rejected revolutionary Marxism. Later the party would move towards Marxism and class struggle under the leadership of Azedo Gneco. His death in 1911 resulted in a number of fractures in the party that would culminate in some of the party splitting away and joining the Portuguese Communist Party in 1919. 
The party then drifted between uncertain positions and lost much of its influence to the rising anarcho-syndicalists and communists. Many members of the party supported the liberal First Portuguese Republic, while a vocal dissident minority supported revolutionary activity. After the success of the German Revolution, the revolutionary minority gained influence and shifted the party leftward. The party then began cooperating with the communists. Some reformists in the party joined the Republican Party of the Democratic Left.
When the Rose Revolution erupted in 1931, the party supported the revolutionaries. It has become increasingly close to the communists since then, and there is a significant current within the party that advocates for a merger with the Portuguese Communist Party. It was formerly associated with the Labour and Socialist International, an organization of social democratic anti-communist parties, but was expelled in 1931 due to its support for the revolution.Category:Portuguese political parties
