[General Parmenion]

The Macedonians where Greeks of Dorian origin :

Herodotus:

"For in the days of king Deucalion it (i.e. a Macedonian tribe) inhabited the land of Phthiotis, then in the time of Dorus, son of Hellen, the country called Histiaean, under Ossa and Olympus; driven by the Cadmeians from this Histiaean country it settled about Pindus in the parts called Macedonian; thence again it migrated to Dryopia, and at last came from Dryopia into Peloponnesus, where it took the name of Dorian."

(Herod. I, 56, 3 [Loeb, A.D. Godley])


Arrian:

"He sent to Athens three hundred Persian panoplies to be set up to Athena in the acropolis; he ordered this inscription to be attached: Alexander, son of Philip, and the Greeks, save the Lacedaimonians, set up these spoils from the barbarians dwelling in Asia."

(Arr. I, 16, 7 [Loeb, P. A. Brunt])


"Your ancestors invaded Macedonia and the rest of Greece and did us great harm, though we had done them no prior injury; ... (and) I have been appointed leader of the Greeks ..."

(Arr., Anab. Alex. II, 14, 4)

Here is also what the Persians believed the Macedonians where....

The Macedonians wore a distinctive hat, the “kausia” (καυσία) (Polybius IV 4,5; Eustathius 1398; Arrian, Anabasis of Alexander, VII 22; cf. Sturz, Macedonian Dialect, 41) from the Greek word for heat that separated them from the rest of the Greeks. That is why the Persians called them “yauna takabara,” which meant “Greeks wearing the hat”. The Macedonian hat was very distinctive from the hats of the other Greeks, but the Persians did not distinguished the Macedonians, because the Macedonian speech was also Greek (Hammond, The Macedonian State p. 13 cf. J.M. Balcer, Historia, 37 [1988] 7).
