Profintern
The Red International of Labour Unions (RILU; Russian: Красный интернационал профсоюзов, romanized: Krasnyi internatsional profsoyuzov), commonly known as the Profintern (Профинтерн), was an international body established by the Communist International (Comintern) with the aim of coordinating communist activities within trade unions. Formally established in 1921, the Profintern aimed to act as a counterweight to the influence of the so-called "Amsterdam International", the social-democratic International Federation of Trade Unions (founded in 1919), an organization which the Comintern branded as "class-collaborationist" and as an impediment to revolution.
