The United Secretariat of the Fourth International (USFI) is the largest Trotskyist international organisation. Its major section is the Revolutionary Communist League in France. Trotskyism is the theory of Marxism as advocated by Leon Trotsky. ... The Revolutionary Communist League (Ligue Communiste Révolutionnaire) (LCR) is a French Trotskyist political party. ...

The USFI was created in 1963 by the merger of the International Secretariat of the Fourth International (ISFI) and the U.S. Socialist Workers Party together with its factional allies, constituting a large minority of the International Committee of the Fourth International (ICFI). These groups had been on opposing sides of the split in the Fourth International in 1953. The SWP had always been viewed as the organisation in the ICFI closest to the ISFI, and the key factor in the rapproachment was their shared positive perspective on the Cuban Revolution. 1963 was a common year starting on Tuesday (link will take you to calendar). ... Initially the title International Secretariat of the Fourth International was the name given to the executive committee responsible for the regular operation of the Fourth International (FI) founded in 1938. ... The Socialist Workers Party is a small communist political party in the United States. ... The International Committee of the Fourth International (ICFI) is a Trotskyist international. ... Emblem of the Fourth International The Fourth International was an international organisation of Trotskyist communists. ... 1953 is a common year starting on Thursday. ... The Cuban Revolution was the overthrow of Cuban dictator Fulgencio Batista by the 26th of July Movement and the establishment of a new government led by Fidel Castro in the 1950s. ...

At the time of the June 1963 Reunification Congress the USFI could claim to count a majority of the worlds Trotskyists in its ranks. This would change within the next few years. Thus the Latin American Secretariat which was led by the Argentine Juan Posadas departed the USFI to form the Fourth International (Posadist), within a few months, as did the group around Michel Pablo. Both men would lead small declining international tendencies until their deaths many years later. In the meantime the only mass organisation within the USFI, the Lanka Sama Samaja Party of Ceylon, entered a coalition govenment in that country and was, after a pause expelled. By the time of the 1965 World Congress the USFI could no longer claim the allegiance of a plurality of Trotskysist due to splits and recruitment to its rivals. J. Posadas (1912-1981) (occasionally referred to as Juan Posadas), was the pseudonym of Homero Cristali, an Argentinian Trotskyist. ... The Trotskyist-Posadist IVth International is a Trotskyist international organisation founded in 1962 by Juan Posadas who was leader of the Latin America Bureau of the Fourth International in the 1950s as well as the section of the FI in Argentina. ... Michel Pablo (August 24, 1911 - February 17, 1996 ) was the pseudonym of Michel N. Raptis, a Greek Trotskyist leader. ... LSSP main office in Colombo Lanka Sama Samaja Party, a trotskyist political party in Sri Lanka. ... 1965 was a common year starting on Friday (the link is to a full 1965 calendar). ...

The organisation suffered many splits over the following years, most notably when the SWP (USA) left in 1983 and the SWP (Australia) a few years later, but is still widely reckoned to be the largest and probably the most widespread Trotskyist international tendency. 1983 is a common year starting on Saturday of the Gregorian calendar. ...
