On December 7, 1941, the Japanese attack on Pearl Harbor prompted the United States to join the Second World War, a conflict already thoroughly encompassing the Pacific, Europe, and North Africa. The sudden political shift sparked the emergence of literature related to the war, and an outpouring of literature addressing the complex issues involved in the war. The war effort absorbed writers from all backgrounds, including children’s writers.
For example, Theodore Seuss Geisel, otherwise known as Dr. Seuss, produced hundreds of war-related editorial cartoons for a New York-based newspaper called PM from 1941 to 1943, during the bulk of American involvement in the war. Although normally a children's cartoonist, these political cartoons were directed at adult audiences. often with patriotic messages urging readers to invest in war bonds. Dr. Seuss, then, put his career on hold to support the war effort from the home front.
