Investigation of Un-American Propaganda Activities in the United States

by United States. Congress. House. Special Committee on Un-American Activities (1938-1944)

These are the records of the hearings of the Dies Committee, set up by the US House of Representatives to monitor "Un-American activities" and foreign propaganda before and during the Second World War.

The full title of the series is "Investigation of un-American propaganda activities in the United States: Hearings before a Special Committee on Un-American Activities, House of Representatives, [in the applicable session of Congress], on H. Res. 282, to investigate (1) the extent, character, and objects of un-American propaganda activities in the United States, (2) the diffusion within the United States of subversive and un-American propaganda that is instigated from foreign countries or of a domestic origin and attacks the principle of the form of government as guaranteed by our Constitution, and (3) all other questions in relation thereto that would aid Congress in any necessary remedial legislation." The hearings were held from the third session of the 75th Congress through the second session of the 78th Congress.

The records ran to 17 volumes of testimonial hearings, plus 7 volumes of executive hearings, plus various appendixes. Below, we have links to all of the volumes, mostly at the Internet Archive, but some at other locations. For each volume, we show the dates of the hearings. There may be some date overlap between volumes in some cases.
