True, but he was from Macedonia
http://en.wikipedia.org/wiki/Alexander_the_great
Alexander effectively brought to completion the assimilation of the ancient Macedonians to the Greek world. Since then, "Macedonia" has been a geographical, not an ethnic, term. Today's Slav Macedonians are descendants of Slavs who settled in the area from the 6th century AD and have nothing to do with Alexander. Furthermore, only 40% the geographic area of Macedonia is part of the current state FYRO-Macedonia; 10% is in Bulgaria and 50% in Greece. In fact Alexander's ancient capital is in the Greek part.
