Do you have the Nazi Germany exam tomorrow by any chance? ;)
Before? I'm not entirely sure. You could mention the threat of communism. Due to the Wall Street Crash in 1929, germans lost hope in the weimar as they were considered weak so they turned to radical political parties like communism and nazism. So most of society were divided into left and right wing supporters.
Hope this helped even the slightest. Good luck for the exam! :)
