The increasing entropy of the Greek interstate system in the century between the Peloponnesian War and the Macedonian Empire caused great concern among all political thinkers. Watching their world crumble around them, the Greeks tried to stem the rush of events and re-establish a semblance of peace and order. The writers and orators of Greece agreed of the need for reform in the inter-state system. By the Fourth Century, the Pan-Hellenists presented the most vocal alternative to political chaos and yet their movement never really got off the ground. Attractive as it was, Pan-Hellenism had many shortcomings, not the least of which was that it never developed a strong supporting political theory.
