What Caused World War 2?

After The Great War, the treaties signed among countries were expected to solve the world's problems and prevent the outbreak of another march against one another. However, many agreements, like the Treaty of Versailles, were unfair to countries that lost the conflict, leading to much resentment. The oppressed countries regrouped, forming alliances that would later participate in the Second World War.

Germany's invasion of Poland on September 1, 1939, was the leading cause of World War II. Adolf Hitler had always been aggressive towards Poland; thus, he used the country's alliance with Britain and France as an excuse to declare war.

Who Were the Major Powers Involved?

The Second World War was initiated by the Axis powers of Italy, Germany, and Japan. Adolf Hitler, the German dictator, was determined to invade and attack Poland. For its part, Poland had alliances with British and French militaries for support in case of an attack.

Nazi Germany invaded Poland to divide it between itself and the Soviets. The agreement to divide Poland was signed during the secret German-Soviet Nonaggression Pact in Moscow. The Moscow pact guaranteed that Germany and the Soviets would not attack each other for the next ten years.

In retaliation, France and Great Britain declared war on Germany on September 3, 1939, after it invaded Poland. Allied countries like the United States, the Soviet Union, and China reacted by joining the effort to support their allies, leading to World War II.

In 1941, Germany turned against the Union of Soviet Socialist Republics (USSR) through Operation Barbarossa. In response, the USSR joined the Allies to fight back. The United States of America also entered the war after Japan attacked Pearl Harbor on December 7, 1941.

Imperial War Museums discussed that World War II's outbreak resulted from the appeasement policy that Great Britain and France adopted. The two countries thought they could avoid another armed conflict by giving in to Hitler's demands. Unfortunately, this only made Hitler more aggressive, and he started to attack other countries.

Factors That Contributed to the Aggression

Apart from Germany's invasion of Poland, other factors that contributed to the Second World War are:

Treaty of Versailles

The Allied Powers signed the Treaty of Versailles after The Great War to ensure that such a conflict would never happen again. However, the treaty had a crippling effect on Germany's economy as they were forced to pay huge war reparations. The pact also led to the loss of Germany’s territories. Therefore, Germany was resentful.

The Great Depression

The global economic crisis that started in August 1929 had a significant impact on the countries involved in World War II. For instance, the United States stopped lending money to Europe while Japan's economy declined due to the fall in export demand. The Great Depression increased unemployment, which increased support for fascist regimes such as Adolf Hitler's Nazi party.


After ascending to power, Hitler started to build a strong military by breaking the Treaty of Versailles. He also began to occupy other countries such as Austria and Czechoslovakia in 1936. 

The other Axis Powers, such as Italy and Japan, also strengthened their militaries. The three countries united their armies in 1936, creating the Axis Powers that started the war.

On the other hand, the Allies were not keen on increasing their militaries as they thought that would lead to more violence and aggression.

A Weak League of Nations

The League of Nations was created in 1919 after The Great War to ensure that such a war never happens again. Unfortunately, the League was weak as it did not have its military. Hitler knew this, and he started to break the rules set by the League without facing any consequences. This made other countries lose faith in the organization, and it became one of the factors that led to the outbreak of the war.

Final Thoughts

World War II broke out when the Allied countries reacted to the Axis Powers. However, the underlying causes of the war are militarism, the Treaty of Versailles, the Great Depression, and a weak League of Nations. These factors led to Hitler's aggression, which resulted in World War II.
