Fascist Flag of Spain" by gruff.jones. It is one of two variants he created, but I personally liked this one the best. It uses arrows that gruff.jones describes as: the symbol of the shield of the monarchy of Ferdinand and Isabella and subsequent Catholic monarchs, representing a united Spain and the "symbol of the heroic virtues of the race."
Of course, some of you may be wondering: wasn't Spain fascist already? Well there appears to be some ambiguity about that if Wikipedia can be believed. Francoist Spain was certainly authoritarian and right-wing, but it seems the fascists were never a dominant force in the government. Native Spanish fascism, known as Falangism, actually did use the arrow symbolism, which makes me think that in the timeline where this flag comes from, Spain is unambiguously fascist. They may even be a minor member of the Axis powers if World War II happens on schedule.
How do you think history would have played out if Spain sided with the Nazis in WWII?
