• Lesson 1: Postwar Disillusionment and the Quest for Peace, 1921–1929

    Senator William E. Borah, (R-Idaho), was a prominent American isolationist who  gave a speech on "outlawing war" in 1924.

    Although antiwar organizations existed even before World War I, it was during the interwar period that pacifism became the fastest-growing movement in America. Numerous American politicians, businessmen, journalists, and activists made proposals for multilateral agreements on arms control and collective security. Through an examination of memoirs, photographs, and other primary source documents, students examine the rise of antiwar sentiment in the United States, as well as some of the concrete measures taken during the 1920s to prevent the outbreak of future wars.

  • Lesson 4: The Failure of Diplomacy, September–December 1941

    A Japanese torpedo bomber over Pearl Harbor, Hawaii, December 7, 1941.

    Faced with crippling economic sanctions imposed by the United States, the Japanese government decided in September 1941 to prepare for war to seize the raw materials that they were now unable to obtain from America. Students in this lesson will put themselves in the shoes of U.S. and Japanese diplomats in the final months of 1941.

  • Lesson 4: Victory in the Pacific, 1943–1945

    The dropping of an atomic bomb on the Japanese city of Nagasaki

    The U.S. victory over the Japanese Navy at Midway succeeded in stopping the Axis advance in the Pacific, and by early 1943 the Marines had driven the Japanese from Guadalcanal. This lesson will guide students through the military campaigns of the Pacific theater, tracing the path of the Allied offensives.

  • Lesson 2: Turning the Tide in Europe, 1942–1944

    American tank crew in North Africa, 1942.

    Although it was the Japanese who attacked Pearl Harbor in 1941, U.S. military planners decided that Germany, not Japan, was to be the primary target of operations. This lesson plan will focus on the overall strategies pursued by the Americans and their British allies in the initial months of World War II in Europe.

  • Lesson 4: FDR and the Lend-Lease Act

    "How lend-lease strikes at the Axis," ca. 1940–45.

    This lesson shows students how broadly the Lend-Lease Act of March 1941 empowered the federal government—particularly the President—and asks students to investigate how FDR promoted the program in speeches and then in photographs.

  • Lesson 3: Victory and the New Order in Europe

    Conference of the Big Three at Yalta makes final plans for the defeat of Germany

    By the beginning of 1944, victory in Europe was all but assured. The task of diplomacy largely involved efforts to define the structure of the postwar world. Why and how did the United States attempt to preserve the Grand Alliance as American diplomats addressed European issues?

  • Lesson 1: How "Grand" and "Allied" was the Grand Alliance?

    President Franklin D. Roosevelt signing the Declaration of War against Japan,  December 8, 1941.

    This lesson plan will survey the nature of what Winston Churchill called the Grand Alliance between the United States, Great Britain, and the Soviet Union in opposition to the aggression of Nazi Germany and Imperial Japan.

  • Lesson 2: Legislating Neutrality, 1934–1939

    President Franklin D. Roosevelt tried to keep the U.S. out of World War II as  long as possible.

    Americans in the mid nineteen thirties turned increasingly pessimistic about the possibility of preventing the outbreak of wars through international cooperation and instead moved toward measures designed to prevent the United States from intervening in any foreign war that might occur. In this lesson students examine a series of primary source documents that will help them understand why these laws were passed, and how they were applied in the mid- to late-1930s.

  • Women Aviators in World War II: "Fly Girls"

    Jackie  Cochran, one of America's leading aviators

    This lesson plan explores the contributions of the Women Airforce Service Pilots (WASPs) during World War II, and their aviation legacy.

  • Lesson 3: U.S. Neutrality and the War in Europe, 1939–1940

    Famous aviator Charles Lindbergh

    The outbreak of war in Europe in September 1939 posed a serious challenge to U.S. neutrality. On the one hand, Americans' sympathies lay overwhelmingly with Great Britain and its allies; on the other hand, public sentiment overwhelmingly favored staying out of the war. Through a study of contemporary documents, students learn about the difficult choices faced by the Roosevelt administration during the first fifteen months of World War II, culminating in the decision to provide direct military aid to Great Britain.
