That sense of being one people allowed each Greek state and its citizens to contribute their values, experiences, traditions, resources, and talents to a new national identity and psyche. It was not until Philip's reign that a common sentiment of what it meant to be a Hellene reached all Greeks. Alexander took this culture of Hellenism with him to Asia, but it was Philip, as leader of the Greeks, who created it and in doing so made the Hellenistic Age possible.
He [Philip] also recognized the power of pan-hellenic sentiment when arranging Greek affairs after his victory at Chaironeia: a pan-hellenic expedition against Persia ostensibly was one of the main goals of the League of Corinth.
In the end, the Greeks would fall under the rule of a single man, who would unify Greece: Philip II, king of Macedon (360-336 BC). His son, Alexander the Great, would lead the Greeks on a conquest of the ancient Near East vastly expanding the Greek world.
