Giulio Cesare Andrea "Julius" Evola was an Italian far-right philosopher. Evola regarded his values as aristocratic, monarchist, masculine, traditionalist, heroic, and defiantly reactionary. An eccentric thinker in Fascist Italy, he also had ties to Nazi Germany; in the post-war era, he was an ideological mentor of the Italian neo-fascist and militant Right.

In political science, a reactionary or a reactionist is a person who holds political views that favor a return to the status quo ante—the previous political state of society—which the person believes possessed positive characteristics that are absent from contemporary society. As a descriptor term, reactionary derives from the ideological context of the left–right political spectrum. As an adjective, the word reactionary describes points of view and policies meant to restore a status quo ante.
