What are three factors that lead to the rise of facism in germany ? whos the braiinlest ?

The Treaty of Versailles lead Germany into many debts, humiliation, and the responsibility to pay for reparations which they couldn't do.

Fascism grew in Germany for a few reasons.
Post WW1 Germany suffered from great economic turmoil and social issues, which was only worsened by the Treaty of Versailles basically putting the blame for WW1 on Germany. Fascism was able to rise because the people of Germany were desperate to be removed from their current status and returned to the strength that it once had. Fascist leaders gained followers by promoting anti-semetic views, giving them a scapegoat for their troubles and giving the people a reason to unite.
