International Workers' Unity – Fourth International

A worldwide revolutionary socialist organization founded in 1997 in Barcelona. The political orientation of this organization is based on the theoretical foundations of the Ukrainian Leon Trotsky and the Argentinian Nahuel Moreno. Organizations such as the Workers' Socialist Current (CST) in Brazil, the Socialist Left (IS) in Argentina, and the Socialism and Liberty Party (PSL) in Venezuela are part of the UIT-CI. The UIT-CI publishes the journal International Correspondence. Some organizations that make up the UIT-CI emerged from splits in the International Workers League – Fourth International (LITci).
