From the Scramble for Africa to the trenches of the Western Front, from the Treaty of Versailles to the rise of fascism, Nazism, and Stalinism, to the Holocaust and the atomic bomb — how imperial rivalry, total war, and totalitarianism reshaped Europe and the world between 1914 and the mid-20th century.
Six ways to master Unit 8 — pick whichever fits how you like to study.
Seven topics from the College Board CED, in order.
Unit 8 opens with the New Imperialism of the late 19th century, as European powers — driven by economic competition, nationalist prestige, and Social Darwinist "civilizing mission" rhetoric — carved up Africa at the Berlin Conference and expanded their empires across Asia, provoking resistance from colonized peoples. That same combustible mix of nationalism and imperial rivalry, layered with rigid alliance systems (the Triple Alliance and Triple Entente) and unchecked militarism, exploded into World War I after the assassination of Archduke Franz Ferdinand in 1914. The war introduced a new kind of total war — trench warfare, chemical weapons, and entire societies mobilized on the home front — and its strain helped trigger the Russian Revolution of 1917.
The war's end brought the punitive Treaty of Versailles, which assigned Germany war guilt and crushing reparations, created the League of Nations, and presided over the collapse of the Austro-Hungarian, Ottoman, Russian, and German empires. The resulting interwar instability — German hyperinflation and the Great Depression — created fertile ground for totalitarianism: Mussolini's fascism in Italy, Hitler's Nazism in Germany, and Stalin's brutal rule in the Soviet Union. Western democracies' policy of appeasement failed to contain Hitler's aggression, and World War II brought Blitzkrieg conquest, the systematic genocide of the Holocaust, a savage Eastern Front, and the deliberate targeting of civilian populations on a scale never seen before. The war ended with the Allied invasion at D-Day, the atomic bombings of Japan, the division of Germany and Europe, the beginnings of decolonization, and the founding of the United Nations.
