Fourth International (post-reunification)

Fourth International (post-reunification)

The Fourth International (FI) (founded in 1938) is a Trotskyist international. In 1963, the majorities of the two public factions of the Fourth International reunited (the International Secretariat -ISFI and the International Committee -ICFI) electing a United Secretariat of the Fourth International. In 2003, the United Secretariat was replaced by an Executive Bureau and an International Committee, although other Trotskyists still refer to the organisation as the USFI or USec.
