"Little is known of the Macedonian army before the reign of Philip II. Certainly, the area which the earlier Macedonian kings drew their recruits was limited only to lowland Macedonia. The only effective arm appears to have been cavalry. These horsemen, generally acknowledged as the best in Greece, were drawn from the local nobility[...]The only really effective infantry in this period appears to have been drawn from southern Greeks settled within Macedonia's borders who fought as hoplites."
