Franco wasn’t charismatic; in fact, as the story goes, he was so icy that Hitler was afraid of him. He came to power by using the army, not a mass party or a large band of violent thugs. He didn’t create a cult of personality. He didn’t try to make Spain great again by invading South America. And yet, he was unquestionably a fascist.
Most of the definitions of fascism focus on the common characteristics of the Hitler and Mussolini movements and ignore Franco. They shouldn’t. That’s why my definition of fascism is simpler: the pursuit of reactionary goals by extraconstitutional means.
