The Nazis rose to prominence because as radicals would demonstrate and riot in Weimar Germany, the Brownshirts were the people that would pull up in trucks and engage them in street combat. German people longing for a restoration of order saw them as the solution to unrest problems the government couldn’t/wouldn’t address.
Before all of the later horrors they unleashed, the Nazis stopped the communist revolution in Germany dead in its tracks - exactly as Mussolini in Italy and Salazar in Portugal had done, and as Franco would do in Spain.
As it happened, many of those Commie agitators in Germany who were defeated in those battles later went on to join the National Socialist Party. “If you can’t beat ‘em, join ‘em”.
