United Secretariat of the Fourth International

The United Secretariat of the Fourth International (USFI) is a Trotskyist organization formed to promote and coordinate the political ideas and activities derived from the teachings of Leon Trotsky, a key figure in early Soviet politics and Marxism. Established in the late 1950s, it aims to develop a worldwide revolutionary movement advocating for socialism, internationalism, and workers' rights. The USFI unites various Trotskyist groups across different countries, focusing on issues like anti-capitalism, anti-imperialism, and social justice, striving to create a more equitable society that reflects Trotsky's vision for a democratic socialist world.
