It just occurred to me that the first foreigners to resist Fascism were Muslims

Specifically, they were Libyans who had already been resisting Italian colonialism for a decade.

Sadly, this also means that the first foreign victims of a Fascist government were probably Muslims too, many of whom perished in concentration camps. (As a preinstitutional movement, on the other hand, Fascism’s first foreign victims were most likely Croats or Slovenes.)
