Fascists identified their primary opponents as the socialists on the left who had opposed intervention in World War I. The Fascists and the rest of the Italian political right held common ground: both held Marxism in contempt, discounted class consciousness and believed in the rule of elites. The Fascists assisted the anti-socialist campaign by allying with the other parties and the conservative right in a mutual effort to destroy the Italian Socialist Party and labour organizations committed to class identity above national identity.
