Top 5 Cause of WWII

1) “Stab In The Back”
The number one cause of World War II was because of the “Stab in the Back” myth. It was the idea that German never lost World War I. The people of Germany thought that the government betrayed them in a way. They figured that since the war was never fought on German land that they did not lose World War I. The “stab in the Back” myth brought about a lot of German nationalism and distrust in their government.
2) Disobey The Treaty Of Versailles
The second most prominent cause was how Germany disobeys the restrictions stated at the Treaty of Versailles. At the treaty there were many restrictions made on the German military. According to the treaty Germany could only have a certain number of men in their army, as navy with only so many ships, they could not have an air force, and the Rhineland was to be demilitarized. The Germans disobeyed all of these restrictions.
3) Appeasement
Another top cause the idea of appeasement. Appeasement was what the other European countries did when Germany was breaking the Treaty of Versailles.
They would just tell them to stop but would not do anything about it. They did this to avoid more conflict. This gave Germany the possibility to rebuild their army.
4) Soviet Non-aggression pact
The Soviet Non-Aggression was a huge reason for World War II. It allowed Hitler to move about Europe without the fear of Russia trying to stop them. The pact made it so that the Germans would only be fighting a one front war. Shortly after the pact was sign World War II began.
5) Invasion of Poland
The most obvious cause and is recognized as the beginning of the war was when Germany invaded Poland. This was the first time that military forces were put into action. Germany invades Poland on September 1, 1939, and then two days later on September 3, 1939, Great Britain and France declare war on Germany.
