60-Second Review
Express reviewA condensed, point-by-point summary of the module, for reviewing right before a test or exam.
- The Unfinished Peace: Versailles, the League of Nations, and the Rise of Axis Revisionism. The failures of Versailles and the League of Nations opened the door to Axis territorial revisionism in the 1930s.
- Appeasement and the Collapse of the Postwar Order (1935-1939). British and French appeasement failed to check German remilitarization, the Anschluss, and the dismemberment of Czechoslovakia.
- The Outbreak of War: Danzig, the Nazi-Soviet Pact, and the Invasion of Poland. The Danzig crisis, the Pact of Steel, and the Molotov-Ribbentrop Pact converged in the German invasion of Poland in September 1939.
- Blitzkrieg Triumphant: The Fall of France and the Battle of Britain (1940). German Blitzkrieg overran Scandinavia and France in 1940, though the Luftwaffe failed to subdue Britain from the air.
- Operation Barbarossa and the Turning of the Tide in the East (1941-1943). Barbarossa, Moscow, Stalingrad, and Kursk marked the rise and collapse of German fortunes on the Eastern Front.
- The War Becomes Global: Pearl Harbor, North Africa, and the Pacific. Pearl Harbor globalized the conflict, joined by the North African desert campaigns and Allied island-hopping in the Pacific.
- The Liberation of Europe and the Fall of the Third Reich (1943-1945). From the Italian campaign to D-Day, the Ardennes, and the fall of Berlin, the Allies closed in on Nazi Germany.
- The Pacific Endgame, the Atomic Bomb, and the War's Human Cost. Iwo Jima, Okinawa, and the atomic bombings of Hiroshima and Nagasaki brought a war of unprecedented human cost to its end.
