The battle over Alexander

Was Alexander a Greek or a Macedonian? And if a Macedonian, which Macedonia? The battle rages. But did not Demosthenes say of Alexander's father that he was "not only no Greek, nor related to the Greeks, but not even a barbarian from any place that can be named with honour, but a pestilent knave from Macedonia, whence it was never yet possible to buy a decent slave." Of course, he was no Slav either. Perhaps he was English.
