The Second World War: Causes, Early Conflicts, and Global Consequences (Chapter 26-27)

The Causes of the War: Unsettled Quarrels, Economic Fallout, and Nationalism

  • Unsettled Quarrels
    • Many disputes from World War I remained unresolved after the war.
    • The Treaty of Versailles imposed heavy reparations on Germany, fueling resentment and a desire for revenge.
    • Territorial disputes simmered in Europe and Asia.
  • Economic Fallout
    • The Great Depression devastated global economies, creating fertile ground for extremist ideologies.
    • In Germany, mass unemployment helped Adolf Hitler and the Nazi Party gain support by promising jobs, military expansion, and national revival.
  • Nationalism
    • Rising nationalism in Germany, Italy, and Japan encouraged expansionist policies.
    • Fascism in Italy under Mussolini and militarism in Japan drove aggressive conquests.
    • Hitler’s ideology of racial superiority fueled ambitions for Lebensraum (living space) in Eastern Europe.

The 1930s: Challenges to the Peace and Appeasement

  • The League of Nations proved weak in stopping aggression (e.g., Japan’s invasion of Manchuria in 1931, Italy’s conquest of Ethiopia in 1935).
  • Hitler remilitarized the Rhineland (1936), annexed Austria (Anschluss, 1938), and claimed the Sudetenland in Czechoslovakia.
  • Britain and France pursued appeasement, believing concessions could prevent war, culminating in the Munich Agreement of 1938. This policy ultimately emboldened aggressors.

The Beginning of the War in Europe

  • Poland’s Invasion (1939)
    • Germany invaded Poland on 1\,\text{September}\,1939, prompting Britain and France to declare war.
  • Blitzkrieg Tactics
    • Rapid mechanized attacks combining tanks, aircraft, and infantry to overwhelm opponents.
    • By mid-1940, Germany had conquered much of Western Europe, including France, forcing Britain to stand alone.

Not Alone: The Battle of Britain and the Beginnings of a Global War

  • Battle of Britain (1940)
    • Britain’s Royal Air Force repelled the German Luftwaffe in the first major campaign fought entirely in the air.
  • Global Conflict Emerges
    • Japan expanded its war in China and targeted Southeast Asia.
    • The United States began supplying Britain and the USSR through Lend-Lease.
    • By late 1941, the war spanned multiple continents, with the Japanese attack on Pearl Harbor bringing the US fully into the conflict.

The Rise and Ruin of Nations: Germany’s War in the East and the Occupation of Europe

  • Operation Barbarossa (1941)
    • Germany invaded the Soviet Union, seeking to destroy communism and seize resources.
    • The Eastern Front became the deadliest theater of the war, with massive casualties at battles like Stalingrad and Kursk.
    • Occupied Europe suffered severe repression, forced labor, and exploitation.

The Racial War, Ethnic Cleansing, and the Holocaust

  • Nazi ideology drove genocidal policies, especially against Jews, Roma, Slavs, and other groups deemed “inferior.”
  • Holocaust
    • The systematic extermination of about 6{,}000{,}000 Jews in ghettos, concentration camps, and extermination camps.
    • Ethnic cleansing and mass killings also occurred in Eastern Europe and the Balkans.

Total War: Home Fronts, the War of Production, Bombing, and the Bomb

  • Total War required mobilizing entire economies for war.
    • Factories converted to produce weapons; women entered the workforce; propaganda campaigns kept morale high.
  • Strategic bombing
    • Targeted military and civilian infrastructure; exemplified by the Blitz in Britain and firebombing in Germany and Japan.
  • Scientific advances
    • Led to the creation of the atomic bomb under the US Manhattan Project.

The Allied Counterattack and the Dropping of the Atomic Bomb

  • Turning Points
    • Victories in North Africa, Italy, Normandy (D-Day, 1944), and the Soviet push from the East.
  • The Pacific War
    • Fierce island battles like Iwo Jima and Okinawa.
  • The Atomic Bombings and Japan’s Surrender
    • In August 1945, the US dropped atomic bombs on Hiroshima and Nagasaki, forcing Japan’s surrender.

Conclusion

  • WWII reshaped global power, leading to US and Soviet dominance, decolonization movements, and the formation of the United Nations.
  • The war left deep scars but also sparked a new era of geopolitical rivalry—the Cold War.
