The Fourth International (FI) (founded in 1938) is the communist international organisation consisting of followers of Leon Trotsky (Trotskyists), with the declared dedicated goal of helping the working class bring about socialism. Historically, the Fourth International was established in France in 1938: Trotsky and his supporters, having been expelled from the Soviet Union, considered the Comintern or Third International to have become "lost to" Stalinism and incapable of leading the international working class to political power. Thus, Trotskyists founded their own, competing "Fourth International".
