How are Nazism and Fascism alike and different?
maksim [4K]
Alike: dictatorship is led by a leader who has all of the power and glorify violence
you cant have freedom of speech and strongly <span>against </span>  

different:The most important difference between Fascism and National Socialism is the latter’s racist character and accent on ethnicity. Granted, Mussolini’s regime in a later stage did contain racist elements, but this was due mainly to its ties with Hitler and the Nazis. Other Fascist regimes that were established around the same time in Europe – the ones in Spain under Franco and Portugal under Salazar – could not be accused of fundamentally embracing racism either. As a result, Fascist-like regimes tended not to have any problems with Jews either and if they did, it was – just like Italy – due to their ties with Nazi-Germany. This enabled some Jews – like Mussolini’s mistress Margherita Sarfatti – to eventually become Fascists themselves. In the Netherlands, even the National Socialist Movement had some Jewish members at first since it did not start out as an anti-Semitic organization.

Another important difference is that Fascists favor corporatism (meaning that the sociopolitical organization of a society is to be led by large interest groups) whereas Nazis don’t. Taken everything in consideration, it may be stated that the main difference between Fascism and National Socialism can be described as follows: Fascists focused more on their own state, whereas race was more important to the Nazis.
