The Committee to Defend America by Aiding the Allies was formed in 1940 to encourage American interest in aiding Great Britain, and ultimately in entering the war in Europe and defeating the Axis powers. The material collected here is only a fraction of the propaganda which was circulated. Included as well is some material by other similar groups active between 1940 and 1942. These materials were donated to the McCormick Library in 1980 by Northwestern University Archives who received them as part of a larger collection. For related materials, see also the America First Collection (series MS10).
