International Spartacist Tendency

The International Spartacist Tendency, now renamed the International Communist League (Fourth Internationalist) is an organisation of various small Trotskyist groups named the Spartacist League, most notably in the United States. They have no connection with the original Spartacist League beyond being revolutionary socialists.

The group originated at the Revolutionary Tendency in the American Socialist Workers Party, formed in 1961, seeing themselves as loyal to the International Committee of the Fourth International while the SWP were keen to leave. After leaving the SWP and splitting, they renamed themselves in 1964, but were expelled from the ICFI in 1966.

The groups see themselves as propagandists, and devote most of their time in attempts to discredit other socialist groups, sometimes simply disrupting their activities, rather than participating in parliamentary or trade union activity. They also take pro-Stalinist viewpoints, opposing the fall of the Berlin Wall and using slogans such as "Support North Korea's right to nuclear weapons!"

The US group publishes the newspaper Workers Vanguard, while the UK group publishes Workers Hammer.
