Socialist International

The Socialist International (SI) is a worldwide group which wants to establish democratic socialism. Most of its members are democratic socialist, social democratic, and labour political parties.

 History 
Its name is from the Second International, which was formed in 1889 and dissolved on the eve of World War I in 1914.

Some of the Second International's most famous actions were its 1889 declaration of 1 May as International Labour Day and its 1910 declaration of 8 March as International Women's Day. The Second International was split by the outbreak of World War I.  A small part carried on as  the International Socialist Commission. The International re-formed in 1923 (as the Labour and Socialist International), and was re organised again, in its present form, after World War II.  Many social democratic and socialist parties had been suppressed in Nazi-occupied Europe.

Since World War II, the SI helped social democratic parties to re-start themselves when dictatorship gave way to democracy in Portugal (1974) and Spain (1975).

Until its 1976 Geneva Congress, the Socialist International had few members outside Europe and no formal involvement with Latin America.The Dictionary of Contemporary Politics of South America, Routledge, 1989 In the 1980s, most SI parties gave their backing to the Nicaraguan Sandinistas (FSLN), whose left-wing government had incited hatred from the United States.  Since then, the SI has admitted as member-parties not only the FSLN but also the centre-left Puerto Rican Independence Party, as well as the ex-Communist parties such as the Italian Democrats of the Left (Democratici di Sinistra (DS)) and the Front for the Liberation of Mozambique (FRELIMO).

The Party of European Socialists, a European political party active in the European Parliament, is an associated organisation of the Socialist International.
