Trotskyist Fraction – Fourth International

The Trotskyist Fraction – Fourth International is a political international of Trotskyist political organizations that claim to adhere to the political legacy of the Fourth International. It was founded in 1989 by former members of the International Workers League (IWL-FI) who were expelled from the IWL-FI in 1988. It regarded itself initially as an "external fraction" who had been wrongly expelled.

Its militants in Argentina founded the Socialist Workers' Party (PTS) in 1988, which from 1988 to 1990, had three splits: first when a number of militants returned to the Argentinian Movement for Socialism (MAS) party, then when another group of militants sympathized with the British Workers Revolutionary Party (Worker Press) and the third when supporters of León Pérez (former member of the International Secretariat of the IWL-FI) decided to follow a mass party perspective (as opposed to a vanguard party).

These splits forced the PTS to make a balance and self-criticism. This resulted in a further development. The PTS questioned the "update" of the Transitional Program that Nahuel Moreno, the leader of the IWL-FI, had made (his so-called theory of "Democratic Revolution"). The PTS regarded Moreno's update as an "anti-Trotskyist revision" of Leon Trotsky's Theory of Permanent Revolution. This led to a break with Moreno's and IWL-FI's political tradition and ideology (termed Morenoism).

In 1998 it emerged as the Trotskyist Fraction - International Strategy, founded by the PTS of Argentina, the LTS of Mexico, the LOR of Bolivia and with the endorsements of the Estratégia Revolucionaria (Revolutionary Strategy) group of Brazil and the Clase contra Clase (Class against Class) group of Chile as well as some militant sympathizers in Europe. In 2004, in its second international conference, the TF decided to change the name "International Strategy" to "Fourth International". Following the economic crisis and demonstrations in several countries, the TF-FI has grown in Latin America and Europe and now promotes the formation of a new grouping: An International Movement for a Socialist Revolution - Fourth International, which had its manifesto updated in 2017 and 2018 due to new developments in the international arena.
