Communist Front was originally the term used by the Communist Party USA (CPUSA), and then later by the House Committee on Un-American Activities (HUAC) and the Senate Internal Security Subcommittee (SISS) to label Comintern (Communist International) organizations found to be under the effective control of the CPUSA, with special emphasis on those groups most active during the Great Depression of the 1930s. The term also refers to organizations not originally Communist-controlled which after a time became so, such as the American Student Union. In 1955, the Senate Internal Security Subcommittee published a list of what it described as the 82 most active and typical sponsors of Communist fronts in the United States; some of those named had literally dozens of affiliations with groups that had either been cited as Communist fronts or had been labelled "subversive" by either the subcommittee or the House Committee on Un-American Activities.
