World War 1 because after World War 1 Germany was weak the government have no power of the people it just either join COMMUNIST or FASCIST and people slowly joined Fascist witch Adolf Hitler rise to power and starting to believe inside LIVING SPACE.
World War II: World War I did not directly cause World War II. However, WW1 created several consequences which led to a second World War: New states in Eastern Europe who were weak and ripe for the taking by Hitler. A devastated Germany and France appeased Hitler to prevent another war
Austria-Hungary had invaded and crossed over into, Serbia and Russia was in an alliance with Serbia, so they felt as though they had to help out. Hope this helps.
