World History – 1400 to Present Unit 13 ReviewWorld War II: Causes and Global Impact

Key Events Leading to WWII

• Rise of fascism in Europe during the 1920s and 1930s led to aggressive expansionist policies by Germany, Italy, and Japan
• Germany's violation of the Treaty of Versailles through remilitarization and territorial expansion (Rhineland, Austria, Czechoslovakia) increased tensions
• Japan's invasion of Manchuria in 1931 and China in 1937 demonstrated its imperialistic ambitions in Asia
• Failure of the League of Nations to effectively address international conflicts and enforce collective security
• Formation of the Axis Powers (Germany, Italy, Japan) through a series of agreements and alliances

• Appeasement policy adopted by Western democracies (Britain, France) in an attempt to avoid war by making concessions to aggressive powers
• Nazi-Soviet Non-Aggression Pact (Molotov-Ribbentrop Pact) in August 1939 surprised the world by temporarily aligning Germany and the Soviet Union
• German invasion of Poland on September 1, 1939, triggered the formal start of World War II in Europe

Major Participants and Alliances

Military Strategies and Technological Advancements

• Blitzkrieg (lightning war) tactics employed by Germany emphasized rapid, coordinated attacks using tanks, infantry, and air support to quickly overwhelm opponents

Global Economic Impact

• Massive mobilization of resources and labor to support the war effort led to significant economic changes
  • Shift towards war production and government control of industries

• Disruption of international trade routes and blockades affected global commerce and supply chains
• Increased government spending and borrowing to finance the war led to rising national debts
• Wartime innovations and technological advancements (synthetic materials, penicillin) had lasting impacts on postwar economies
• Bretton Woods Conference (1944) established a new international monetary system and created institutions (International Monetary Fund, World Bank) to promote economic stability and reconstruction

Social and Cultural Changes

• Mobilization of women into the workforce to replace men serving in the military
