"At the end of the bronze age a residue of Greek tribes stayed behind in Southern Macedonia [...] one of these, the "Makedones" occupied Aegae and expanded into the coastal plain of lower Macedonia which became the Kingdom of Macedon; their descendants were the Macedonians proper of the classical period and they worshipped Greek gods. The other Greek tribes became intermingled in upper Macedonia with Illyrians, Paeonians and Thracians[...] in the early 5th century the royal house of Macedon, the Temenidae was recognized as Greek by the Presidents of the Olympic Games. Their verdict was and is decisive. It is certain that the Kings considered themselves to be of Greek descent from Heracles son of Zeus. "Macedonian" was a strong dialect of very early Greek which was not intelligible to contemporary Greeks."
