Step-by-step explanation:
1. The Great Depression (In an effort to pay back their debts following WWI, Germany printed money. This caused hyperinflation and the country, as well as the the world, fell into a huge economic depression).
2. The establishment of Nazi Germany and Adolf Hitler's dictatorship (Hitler used the Jewish population as a scapegoat and implemented inhumane conditions to eliminate them. Hitler desperately wanted to expand his territory, which lead to the invasion of Poland in 1939. This is what caused the UK and France to declare war on Germany, which is why it is largely regarded as the start of WWII).
