Summary
Highlights
Unit 7 covers global conflicts from 1900, starting with the lingering effects of the Berlin Conference and industrial imperialism. European states like Britain, newly unified Germany, and Italy aggressively pursued colonies and resources. Russia and Japan also expanded, leading to the Russo-Japanese War. Other Asian states, like China, struggled under European influence. This period saw significant power shifts and discontent with authoritarian governments in Russia, the Qing Dynasty, the Ottoman Empire, and Mexico, leading to various revolutions and regime changes.
The causes of World War I can be remembered by the acronym MAINE: Militarism, Alliance System, Imperialism, and Nationalism. Militarism refers to the arms race fueled by new industrial technologies. The complex web of military alliances ensured a wider conflict. Imperialism created rivalries over resources and colonies. Nationalism fostered a belief in national superiority, escalating tensions. The assassination of Archduke Franz Ferdinand in the Balkans, a region with strong Slavic nationalist sentiments and a history of Ottoman and Austro-Hungarian control, acted as the spark that ignited the powder keg, drawing in allied nations and leading to declarations of war.
World War I was characterized by horrific new technologies like machine guns and poison gas, leading to a deadly stalemate in trench warfare. It was a 'total war,' involving civilians on the home front through rationing, propaganda, and women working in war production. The entry of the United States in 1917, spurred by the sinking of the Lusitania and the Zimmermann Telegram, provided fresh troops that ended the stalemate. The war concluded with the Treaty of Versailles, which placed harsh reparations and blame on Germany, sowing the seeds for future conflict. The post-war period was marked by anxiety and disillusionment, with Germany facing hyperinflation and the global economy suffering from the Great Depression, prompting new economic theories like Keynesian economics and policies like the US New Deal.
The interwar period saw varied economic recovery and the rise of fascism. Japan's economy recovered fastest. Russia, under Vladimir Lenin and later Joseph Stalin, introduced economic plans (NEP, Five-Year Plans) and collectivization, leading to significant famines. Mexico nationalized its oil industry. Fascism, characterized by extreme nationalism, violence, and scapegoating, first emerged in Italy under Benito Mussolini. Germany saw the rise of the Nazi Party and Adolf Hitler, who blamed Jews for economic problems and implemented anti-Semitic laws leading to Kristallnacht, foreshadowing the Holocaust. Colonized peoples also recognized the hypocrisy of European powers who promoted self-determination for white regions but not for their colonies, fueling nationalist movements in India (led by Gandhi with non-violent civil disobedience) and Africa.
World War II was largely caused by Adolf Hitler's aggressive expansionist policies, the failure of the League of Nations, and the policy of appeasement. Hitler openly violated the Treaty of Versailles by rearming Germany. European powers, wary of another war, pursued appeasement, allowing Hitler to annex the Sudetenland. However, his subsequent invasion of Czechoslovakia and then Poland in 1939 triggered declarations of war from Britain and France, officially starting World War II. Japan, prior to the war in Europe, had also been engaged in imperialistic conquests in Asia, including the invasion of Manchuria and the atrocities in Nanking (Nanjing).
World War II saw significant changes and continuities in warfare. It was faster-moving with Blitzkrieg tactics, unlike the stalemate of WWI. Aerial warfare with bombers and the introduction of atomic weapons marked technological advancements. Continuities included it being a total war, extensive use of propaganda (e.g., Rosie the Riveter), rationing, and the global nature of the conflict. Governments used ideologies like fascism and communism to mobilize all state resources. Notably, the Soviet Union, initially in a non-aggression pact with Germany, switched to the Allied side after Hitler's invasion, bearing a significant brunt of the war's casualties. The war ended in Europe with Germany's defeat (VE Day) and in the Pacific with the atomic bombings of Japan.
Unit 7 also covers mass atrocities and genocides. The Armenian Genocide during WWI, where the Young Turks' 'Turkification' policies led to the systematic killing of Armenians in the Ottoman Empire, is a significant early example. The Holocaust, perpetrated by the Nazis during WWII, systematically murdered over six million Jews, along with other targeted groups. In Asia, Japanese forces committed horrific atrocities during the Nanking Massacre (Rape of Nanking) against Chinese civilians. Even after WWII, genocides continued, such as the Rwandan Genocide in 1994 targeting the Tutsi people and the Cambodian Genocide under Pol Pot's Marxist regime. The video stresses the importance of recognizing dehumanizing language and propaganda as precursors to ethnic violence and the need for collective action to prevent future atrocities.
