After World War I, the Second International was revived (1919) by moderate socialists, and a Vienna, or Two-and-a-Half, International was formed (1921) from splinter leftist groups that spurned both the Second International and the Comintern. In 1923 the Second and Vienna internationals merged to form the Labor and Socialist International, which lasted until the beginning of World War II. After the war this International was continued under the name of the Socialist International, and it exists today. Among its tenets are support for internationally integrated economic systems and civil rights and opposition to left-wing and right-wing totalitarianism and all forms of exploitation and enslavement.
