What were the causes of World War I and II ?
WWI was caused by the murder of an Austrian prince. And WWII was caused by the attack on Pearl Harbor
Ignorant selfish men? Oh i forgot egoistic
the first was world war was because some person was shot and there was alliances, and so when he was shot the war just exploded. The second was because of Hitler going around and taking most of Europe.
The thirst for world power and domination of Europe
Ummm people God bless you :)
