text: Emerging America, in a partnership with the Abraham Lincoln Brigade Archives, has a produced a primary source-filled lesson on the Spanish Civil War (1936-1939) – arguably the start of World War II. In this complex conflict, all sides used propaganda to sway the opinions of Spanish citizens and nations around the globe. The most apparent form of propaganda used was posters created by each side of the war. The Library of Congress has over 120 colorfully detailed posters. Students will use these posters to discuss and evaluate the tools of persuasion.
