Who were the Macedonians? As an ethnic question it is the best avoided, since the mainly modern political overtones tend to obscure the fact that it really is not a very important issue. That they may or may not have been Greek in whole or in a part—while an interesting anthropological sidelight—is really not crucial to our understanding of their history. They made their mark not as a tribe of Greeks or other Balkan peoples, but as Macedonians. This was understood by foreign protagonists from the time of Darius and Xerxes to the age of Roman generals.
