What were some of the outcomes that happened after ww1 that affected ww2?

Well Germany was not only suffering a humiliating loss, but their economy was utter trash. Stacks of money were needed for just milk. Hitler, once in power, quickly gained love by fixing the economy and Germany in general, and once he had power (that he casually gave himself under the radar) he invaded Poland on September 1st, 1939, which kicked off World War 2

Although there was not actual fighting in this war, the possibility of nuclear warfare was a real threat. In conclusion, WWI had a large effect on WWII. The end of WWI, and the economic problems that WWI caused were a major factor in WWII. This allowed for powerful political leaders to rise up.

Hope it helps you
