Quickly put together flag of a speculative macedon-roman empire.
from /r/vexillology Top comment: I basically just went "Oh shit what if greco roman in real" and made this. The idea is this takes places in an alternate history of ours in which Alexander the Great was not assasinated, and his empire continued to thrive without being split, and with eventually encountering the romans, they unite together. First going through a tough civil war, as one is a republic and the other one is a monarchy, but later overcoming the problem by introducing both an emperor and senate, basically creating a super empire stretching from iberia to the indus. The elements I used (from inside to outside) were the Vergina sun, a typical greek-style circle, and a roman olive crown. Could've gone way over the top, so this is my most simple take on it.
