FBI File: House Committee on Un-American Activities (HUAC)

From 1938 through 1975, the House Committee on Un-American Activities and the FBI developed a working relationship that both increased the power of the committee and gave the bureau another means of investigating suspected Communists. This file, which contains hundreds of reports centered on HUAC���s major investigations, is divided into three parts: 1938-1945 covers clashes between HUAC chairman Martin Dies and the Roosevelt and Truman administrations; 1946-1969 records the process by which the FBI and HUAC chose their targets; the last section follows HUAC, renamed the Internal Security Committee, in its attempt to protect the FBI from other congressional investigative committees.
