WWII
WWII
Introduction
Welcome to this aiMOOC on World War II – the largest and deadliest armed conflict in human history (1939–1945). In this course, you will learn about the causes, events, consequences, and lasting impacts of WWII. We will look at the war from a global perspective: how it started, how it was fought across Europe, Africa, Asia, and the Pacific, and how it reshaped the world order.
You will also reflect on questions like: Why did WWII break out only 20 years after WWI? What role did dictators such as Adolf Hitler, Benito Mussolini, and Hideki Tojo play? How did alliances like the Allied Powers and Axis Powers determine the course of the war? And what lessons can we learn today about peace, democracy, and international cooperation?
Causes of World War II
After World War I, the Treaty of Versailles left Germany humiliated, facing economic hardship, and political instability. This climate enabled the rise of Fascism and National Socialism. Aggressive expansion policies by Nazi Germany, Imperial Japan, and Fascist Italy destabilized international relations.
Key causes included:
- Harsh conditions of the Treaty of Versailles
- Economic crises during the Great Depression
- Rise of totalitarian regimes in Germany, Italy, and Japan
- Policy of Appeasement by Britain and France
- Failure of the League of Nations
Major Theaters and Battles
WWII was fought across the globe:
Europe
- German Invasion of Poland (1939) – start of the war
- Battle of Britain (1940) – first major air campaign
- Operation Barbarossa (1941) – German invasion of the Soviet Union
- Battle of Stalingrad (1942–43) – turning point in Eastern Europe
- D-Day / Normandy landings (1944) – opening of Western Front
Asia-Pacific
- Japanese invasion of China (1937 onwards)
- Attack on Pearl Harbor (1941) – brought the US into the war
- Battle of Midway (1942) – major naval turning point
- Island hopping strategy of the US
- Atomic bombings of Hiroshima and Nagasaki (1945)
The Holocaust
The Nazi regime carried out the systematic genocide of six million Jews and millions of others, including Roma, disabled people, and political opponents. This crime against humanity is known as the Holocaust. It remains central to the history of WWII and human rights education.
The End of the War
In Europe, WWII ended with the unconditional surrender of Germany in May 1945, after the Battle of Berlin. In Asia, Japan surrendered in August 1945 following the atomic bombings and the Soviet entry into the war against Japan.
Consequences of World War II
The war had far-reaching consequences:
- Over 70 million deaths worldwide
- Destruction of cities and economies
- Founding of the United Nations (UN)
- Beginning of the Cold War between USA and USSR
- Decolonization movements across Asia and Africa
- Development of international law and human rights
