Profintern

The Red International of Labor Unions (, RILU), commonly known as the Profintern (), 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. After entering a period of decline in the middle 1930s, the Profintern was finally dissolved in 1937 with the advent of Comintern's "Popular Front" policy. Provided by Wikipedia
