Fifth International

The phrase Fifth International refers to the efforts made by sections of socialists to create a new Workers' International.

There have been many previous international workers' organisations, and the call for a Fifth International presupposes the recognition of four in particular, all of which regarded themselves as the successor to the previous ones:

In November 1938, just two months after the founding congress of the Fourth International, seven members of the Workers' Party of Marxist Unification (POUM) on trial in Barcelona declared their support for a "fighting Fifth International". The Argentine Trotskyist Liborio Justo, better known as "Quebracho", called for a Fifth International when he broke from Trotskyism in 1941. Another call for a Fifth International was made by Lyndon LaRouche after leaving the Spartacist League in 1965. Later, a 'Fifth International of Communists' was founded in 1994 by several very small former Trotskyist groups around the Movement for a Socialist Future.

In 2003, the League for a Revolutionary Communist International called for the formation of the Fifth International "as soon as possible – not in the distant future but in the months and years ahead". The LRCI changed its name at this time to League for the Fifth International. They became the League for the Fifth International (L5I), which has since grown significantly and as of 2010 has sections in Austria, Britain, Czech Republic, Germany, Pakistan, Sweden, Sri Lanka (the Socialist Party of Sri Lanka) and the United States. The League for the Fifth International campaigns in the European Social Forum and the international labour movement for the formation of a new International. A split from them before they were known as the L5I, the Communist Workers' Group in New Zealand, also argues for a Fifth International.
