Macedonians descended from a Greek tribe which didn't want to be involved with the other Greeks. But when Philip got on the throne, he wanted to unite all the Greeks under his control. The Greeks didn't want a leader of pure "Barbarians" to be on the rule. So they fought back. Philip conquered them in order to begin his campaign in Asia. And not because he was slavic. And that map is from when that area of Greece was controlled by turks. Your country was once controlled by turks and you know that. When we fought back, we wanted the parts around Thessaloniki and Kavala freed. While under the control of the ERE (Byzantines) your "Country" had too many foreigners from the northeast. Mongols. Those moved south because they were nomads. They moved to the balkans, except Greece because ERE didn't want that many slavic people. It allowed only a few.
