9. Different Causes of WWII
1. Treaty of Versailles
The treaty made Germans take all the blame for WWI AND pay all of the war damages.
Italians were also upset by the treaty because they thought they deserved more land.

10. Gemany: Harsh Treaty of Versailles
After WWI, the Treaty of Versailles tried to make conditions that would prevent future war. But the treaty was very mean to Germany.
It created more anger than peace.

11. Different Causes of WWII
2. The Great Depression hurt other countries besides America.
Millions didn’t have jobs. Many people were poor and unhappy. They were willing to listen to anyone who offered a solution to these problems.
Made it easy for dictators to take power.

3. Aggression by the dictators
The dictators of Italy, Germany and Japan started taking land when they wanted it. The League of Nations didn’t try to stop them.

4. The Failure of Appeasement
Hitler continued to try to take land even though it was against the Treaty of Versailles.
He wanted part of a country called Czechoslovakia. Czechoslovakia was willing to fight Hitler.

15. Continued… Great Britain wanted to avoid any fighting.
So Prime Minister (leader of Great Britain) Neville Chamberlain wanted to make a deal with Germany.
He would GIVE Germany PART of Czechoslovakia id Hither promised to STOP taking over other land.
This plan was called appeasement.

16. Why did appeasement fail?
Chamberlain thought that he had made peace and avoided war but he was wrong.
Hitler took MORE land in Czechoslovakia in He had lied to Chamberlain.

17. American Isolation
-Just like during WWI, America tried to stay neutral when WWII started.
They didn’t want to be involved in another war in Europe. (far away)

18. But President Roosevelt knew that the U. S
But President Roosevelt knew that the U.S. would probably get involved later to help those who were being attacked. “ Innocent people are being casually sacrificed to a greed for power. Let no one imagine that America will escape. There is no escape through mere isolation of neutrality. War is like a disease, and like a disease, war is spreading.

19. Why do you think Roosevelt compares war to a disease?
What do diseases and war have in common?
