The Fourth International's (La Verite) roots lie in the Organising Committee for the Reconstruction of the Fourth International (OCRFI), which was established in 1972. It formed a short-lived bloc with Nahuel Moreno's tendency. A Parity Committee which operated in 1979 1980 produced Forty Theses of agreements between the tendencies led by Moreno and Lambert. On that basis, the Fourth International (International Committee) (FI[IC]) was founded in 1980. However, the convergence decelerated because of Lambert's support for the government of Socialist Party (France) and French Communist Party without capitalist ministers, a traditional position of French Trotskyism going back before the death of Trotsky. Moreno's supporters boycotted a General Council of the FI(IC) in the Autumn of 1981 whereupon Lambert declared a split: Moreno's supporters formed the International Workers League; at a meeting on 21–23 December 1981 Lambert's supporters formed the "Fourth International - International Centre of Reconstruction", or ICR.
