The Fourth International (FI) is a revolutionary socialist international organization consisting of followers of Leon Trotsky, also known as Trotskyists, whose declared goal is the overthrowing of global capitalism and the establishment of world socialism via international revolution. The Fourth International was established in France in 1938, as Trotsky and his supporters, having been expelled from the Soviet Union, considered the Communist International as effectively puppets of Stalinism and thus incapable of leading the international working class to political power. Thus, Trotskyists founded their own competing 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 formed by groups which arose as the "Internationalist Bolshevik Faction" within the International Workers League (IWL-FI) in 1989. Regarded at first as an "external fraction" who had been wrongly expelled, from 1988 to 1990 the Argentinian Socialist Workers' Party (PTS) 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 and the third when supporters of León Pérez decided to follow a mass party perspective.

The International Revolutionary Marxist Tendency was an international Marxist group based in France led by Michel Pablo, also known as Michael Raptis, the former secretary of the Trotskyist Fourth International. It resulted as a regroupment of activists expelled from the Fourth International over their opposition to the 1962 re-unification process with the so-called "International Committee of the Fourth International"(ICFI) which had split from the Fourth International in 1953 over the question of entrism sui generis, a form of entryism which involved eschewing overt organisation building efforts in favour of long term participation in social democratic and communist parties. The re-unification process was rushed while Pablo was imprisoned in the Netherlands for illegal activities in support of the Algerian revolution.

The Fourth International was established as an "International Centre of Reconstruction" by co-thinkers of Pierre Lambert, in 1981 who argued that the post-war political evolution of the Fourth International under the leadership of Michel Pablo and Ernest Mandel had taken the FI away from the ideas of its founder, Leon Trotsky. In the opinion of Lambert and his co-thinkers, the FI needed to be reconstructed. In 1993, they formed a new International, which they describe as the Fourth International.
