N. G. L. Hammond Quote

As subjects of the king the Upper Macedonians were henceforth on the same footing as the original Macedonians, in that they could qualify for service in the King's Forces and thereby obtain the elite citizenship. At one bound the territory, the population and wealth of the kingdom were doubled. Moreover since the great majority of the new subjects were speakers of the West Greek dialect, the enlarged army was Greek-speaking throughout.
