A set of authoritarian regimes in the interwar and ww2 period where fascist ideology inspired by Mussolini and later Hitler's NSDAP played a central role. They were characterized by the decline in Monarchism, failure of democracy and the support of great war veterans, like Mussolini and Hitler themselves, who composed their blackshirts and brownshirts and assisted in their rise to power.
Due to ww2 fascism rose in notoriety and many try to pin their enemies as "fascist" or sometimes adopt fascism purely for the shock value, but most of the points here
>>18058163 could be pinned on any authoritarian regime really, even communist regimes. It is thus very ambiguous to use the term "fascist" outside of the 20s, 30s and 40s.
Their ideology was generally hyper-nationalist and viewed despotism and expansionism as justified. Mussolini flip flopped on racial rhetoric and had a jewish gf, but Hitler went all in, suggesting the racial element is largely his design, otherwise candid and open discussion of eugenics and race was not exceptional compared to democratic liberals at the time.
Other fascist parties were generally shills for Hitler and Mussolini while ww2 fascist regimes were puppets of Germany. Falangism was marginal in Spain and only tolerated to get aid from Germany and Italy and deter aggression, Metaxism was superficial for similar reasons, and did not succeed as Italy would invade Greece anyway. The accusation that Pinochet was fascist is spurious considering Pinochet's desire for support from erstwhile Nazi Germany's mortal enemies and lack of interest beforehand.
Unironic fascists like Léon Degrelle and Otto Ernst Remer continued to exist after the war, but only had very small followings.
