Popular frontA popular front is "any coalition of working-class and middle-class parties", including liberal and social democratic ones, "united for the defense of democratic forms" against "a presumed Fascist assault". More generally, it is "a coalition especially of leftist political parties against a common opponent". The term was first used in the mid-1930s in Europe by communists concerned over the ascent of fascism in Italy and Germany, which they sought to combat by coalescing with non-communist political groupings they had previously attacked as enemies.
Front organizationA front organization is any entity set up by and controlled by another organization, such as intelligence agencies, organized crime groups, terrorist organizations, secret societies, banned organizations, religious or political groups, advocacy groups, or corporations. Front organizations can act for the parent group without the actions being attributed to the parent group, thereby allowing them to hide certain activities from the authorities or the public.

Beginning in European countries in the 1920s, it was at its most significant shortly before and during World War II, where the Axis powers were opposed by many countries forming the Allies of World War II and dozens of resistance movements worldwide. Anti-fascism has been an element of movements across the political spectrum and holding many different political positions such as anarchism, communism, pacifism, republicanism, social democracy, socialism and syndicalism as well as centrist, conservative, liberal and nationalist viewpoints.
Communist InternationalThe Communist International (Comintern), also known as the Third International, was an international organization founded in 1919 that advocated world communism, and which was led and controlled by the Communist Party of the Soviet Union. The Comintern resolved at its Second Congress in 1920 to "struggle by all available means, including armed force, for the overthrow of the international bourgeoisie and the creation of an international Soviet republic as a transition stage to the complete abolition of the state".
