The Red International of Labor Unions (Russian: Красный интернационал профсоюзов, romanized: Krasnyi internatsional profsoyuzov, RILU), commonly known as the Profintern (Russian: 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. 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.
