What you’ll learn

  1. Out of the Ashes: CausesUnderstand how the aftermath of World War I, economic collapse, and the rise of fascism set the stage for a second global war.The harsh Treaty of Versailles and the Great Depression bred resentment and instability in Germany. Fascist and militarist regimes rose in Germany, Italy, and Japan, each bent on conquest. Western policies of appeasement failed to stop Hitler, who secured a pact with the Soviet Union before striking.

The War Begins: 1939 to 1941Trace the outbreak of war in Europe from the invasion of Poland through the Battle of Britain and the German invasion of the Soviet Union.Germany's invasion of Poland on 1 September 1939 began the war, followed by rapid conquests across Western Europe. Britain survived the air war of the Battle of Britain. In 1941 Hitler invaded the Soviet Union, opening the war's deadliest front.
  3. A Truly Global WarExamine how the war spread worldwide after Pearl Harbor and identify the turning point in the Pacific.Japan's attack on Pearl Harbor in December 1941 brought the United States into a now-global war fought across Europe, Africa, Asia, and the oceans. At the Battle of Midway in June 1942, the United States sank four Japanese carriers, marking the turning point of the Pacific war.
  4. The Tide TurnsIdentify the key turning points of 1942 to 1944 that shifted momentum decisively to the Allies.At Stalingrad, the Soviets destroyed a German army and seized the initiative in the east.

  5. The HolocaustUnderstand the Holocaust factually as the systematic, state-sponsored murder of six million Jews and millions of other victims.Nazi persecution of Jews escalated from the loss of rights to systematic murder across occupied Europe. Approximately six million Jewish people were killed in ghettos, mass shootings, and killing centers. The Nazis also murdered millions of others, including Soviet POWs, Polish and Serb civilians, Roma, and people with disabilities.
  6. The War EndsFollow the war's conclusion in Europe and the Pacific, from V-E Day through the atomic bombings to Japan's surrender.Germany surrendered on V-E Day, 8 May 1945, after Hitler's death and the fall of Berlin. In August, atomic bombs struck Hiroshima and Nagasaki, killing well over a hundred thousand people. Japan surrendered, formally signing on 2 September 1945, ending the war.
  7. Cost and LegacyGrasp the staggering human cost of the war and its lasting legacy on the modern world.Scholarly estimates put total deaths at roughly 70 to 85 million, most of them civilians. The war led to the founding of the United Nations, the Nuremberg trials, and the start of the Cold War. Its legacy in technology, human rights, and historical memory still shapes the world today.
