This series consists of letters, memorandums, teletypes, newspaper clippings, reports, logs, statements, notes, legal documents, interviews, transcripts, lists, court records, correspondence and other records contained in case files opened by the St. Louis (Missouri) Field Division of the Federal Bureau of Investigation (FBI). The records constitute investigative case files on persons, organizations, groups, or events believed by the FBI to have the potential to ignite civil unrest that might possibly require the use of Federal troops, such as planned demonstrations and protest marches. Many of the records encompass surveillance of groups considered "agitator" organizations, such as various civil rights- and socialist-oriented groups that formed in the 1960s, many of which were specifically targeted by FBI Director J. Edgar Hoover for suspected Communist influence. Some material further pertains to investigations of political organizations and groups that formed on college campuses in the 1960s.
