I find it particularly interesting because the Iron Guard was one of only three Fascist political parties to come to power organically (elected to parliament), yet they are either not included or mentioned only briefly in comparative studies of Fascism. Why?
In an attempt to answer my own question, i think its because the Iron Guard do not fit the traditional Fascist model (Paxton "Anatomy of fascism"/Payne "Fascism: comparison and definition". The iron guard were a fanatically religious organization (eastern orthodox), membership was mostly drawn from university students differed radically from Mussolini's Fascism or Hitlers Nazism. Secondly, it may be that the certain archival material has just recently become available due to the soviet iron curtain.
For people who have no idea who the iron guard is: https://en.wikipedia.org/wiki/Iron_Guard
Nobody fits the narrow fascism description except Italy. If we turn the table around and don't start from the founding father, but from the followers we'd actually see that fanatical religious background are pretty common in quasi-fascist organisations at the time.
Students were also one of the core groups of the NSDAP. Universities were one of THE breeding grounds for antisemitism and Fascism in Germany.
I also would not say that they are ignored, it just comes that they weren't that important for the general war history in Europe. Italy was bringing the ideas, and Germany everything else.
Austro-fascism, Slovakian, Baltic, Ukrainian and Hungarian fascism also don't get too much "mainstream publicity". (Ustasha only because of the pseudo-ressurection during the Yugoslav war). Only Spanish fascism gets more recognition, as the Spanish Civil war was such an important ideological battle until this day.
