World War II: causes and impacts

world war II its causes and effects

The world hardly got over to the impacts of World War I, and it witnessed another global war, World War II. It started in 1939 and ended in 1945. Around 70 to 85 million people were killed in this war. The casualties included 6 million Jews, 50 million civilians, and 25 million soldiers. One can clearly understand that wars do not see whether the person, being killed, is a civilian or a soldier. This war was fought across Europe, Africa, Asia, the Pacific Ocean, and the Atlantic Ocean.

Blocs in World War II

The world was divided into two blocs in World War II: Axial Powers and Allied Powers. The Axial Powers were formed by the coalition of Germany, Japan, and Italy. The Allied Powers was consisting of the UK, the USA, USSR, France, China, and Poland.

“Causes of World War II”

“Treaty of Versailles”

“The Treaty of Versailles” is the foremost reason for World War II. This humiliating treaty was signed between Germany and the Allied nations and World War I was officially ended. According to this treaty, Germany had to pay financial reparations for World War I. It had to lose all its territories and give up all its foreign colonies. And Germany was not happy with it.

Hitler’s Militarism

 Germany’s militarism is another reason for World War II. Having grudges against the Treaty of Versailles, Hitler clandestinely started increasing his military and weapons. France and Britain saw it as a counterweight to impede communism’s increasing prevalence. In 1936, Hitler invaded German-speaking areas of Czechoslovakia, the Rhineland, and Austria. He made an alliance called Axial Powers with Japan and Italy.

The policy of Appeasement

In 1930, politicians in France and Britain started believing that the Treaty of Versailles was unjustifiable. This belief was called the “Policy of Appeasement”. This approach allowed Germany to integrate areas in Czechoslovakia where the German language was spoken. It was not permitted to annex the remaining parts of Czechoslovakia. In 1939, Hitler reneged on his promises and captured the whole of Czechoslovakia. France and Britain were not expecting this move. In September 1939, Germany attacked Poland. In response, France and Britain “declare war on Germany. That’s how World War II got started”.

Failure of the League of Nations

League of Nations was an organization that was formed to avoid wars like World War I. All countries were supposed to join this league. And every conflict was essentially solved through dialogues. Unfortunately, it proved unsuccessful. It was because not all countries joined. Neither it had its army to prevent any war. It could not refrain from imperialism which resulted in World War II.

Japan’s Imperialism

Suffering from the economic depression, Japan lost its public trust. Invading China, an area enriched with natural resources, Japan found a way to meet its needs for natural resources. In this scenario, the Philippines was of greater importance, but it was the USA’s territory. Japan could not face mighty America. And took a childish move. And to minimize the USA’s aggression intensity, Japan attacked Pearl Harbor which destroyed many fighter crafts and ships. Soon after this attack, the USA also became part “of World War II”.
