Hi,
I have a historical question regarding Alexander The Great, and his nationality/ethnicity was it Macedonian, Greek, Bulgarian, or a Slav? Because I hear Macedonian nationalists telling us that he's Macedonian not Greek.
But, didn't he spoke Greek, had Greek parents, and was born in Macedon?
It's...eh, it's Complicated. I commend to your attention the work of u/Iphikrates, specifically these two posts addressing this matter exactly.
