For the record,
Alexander did not conquer Greece, he *was* a Greek Macedonian. What is a Greek, you might ask? I opt for the definition of Iscocrastes, i.e., that a Greek is whoever partakes of a Greek education; it has nothing to do with race and such bullshit! And
Alexander spoke Greek, partook of Greek education (as a matter of fact his teacher was none other than
Aristotle) and even gave his horse a Greek name Bucephalus (ox head).
