What were the main reasons for the rise of dictatorship throughout Europe after WW1?

by Lappos

I'm in need of some help researching this subject for a mock exam, and if you're not interested in doing a long writeup, could you help me with finding some good sources so I can research on my own? I've been reading stuff like textbooks, Wikipedia, etc. but I'm struggling to find any good non-encyclopedic sources.
So basically I understand that the Versailles treaty and a need for revenge after losing WW1 inspired nationalistic feelings which helped the dictators rise to power, but I don't understand how several oppressive parties like the Nazis could get the power legally, pretty much at the same time?
