After the victory at Chaeronea, Philip and Alexander marched unopposed into the Peloponnese, welcomed by all cities; however, when they reached Sparta , they were refused, but did not resort to war.  At Corinth , Philip established a "Hellenic Alliance" (modelled on the old anti-Persian alliance of the Greco-Persian Wars ), which included most Greek city-states except Sparta. Philip was then named Hegemon (often translated as "Supreme Commander") of this league (known by modern scholars as the League of Corinth ), and announced his plans to attack the Persian Empire .  
Of all the Causes which conspire to blind
Man's erring Judgment, and misguide the Mind,
What the weak Head with strongest Byass rules,
Is Pride, the never-failing Vice of Fools.
Whatever Nature has in Worth deny'd,
She gives in large Recruits of needful Pride;
For as in Bodies, thus in Souls, we find
What wants in Blood and Spirits, swell'd with Wind;
Pride, where Wit fails, steps in to our Defence,
And fills up all the mighty Void of Sense!
If once right Reason drives that Cloud away,
Truth breaks upon us with resistless Day;
Trust not your self; but your Defects to know,
Make use of ev'ry Friend--and ev'ry Foe.
