And that takes us to 337, right over here, where he's able to establish the League of Corinth. It was only called the League of Corinth after the fact, but he gets the leaders of the significant city-states together in Corinth, that's why it's called the League of Corinth, and they swear their oath essentially to Philip, king of Macedon, who they call the hegemon. And what's really important about that is he's able to unify the Greek city-states outside of Sparta, and in doing so, he sets things up for his son, the famous Alexander the Great, to continue to unify Greece. Alexander the Great's actually able to subjugate Sparta. But then, more famously, he goes off to conquer the entire Persian Empire, and then beyond, in his short life, and we'll have at least another video on that. Now, just to get a feel for what happened at the League of Corinth in 337 BCE, I will share this oath that the various city-states had to commit to, and it says, I swear by Zeus, Gaea, Helios, Poseidon, and all the gods and goddesses, I will abide by the common peace, and I will neither break the agreement with Philip nor take up arms on land or sea, harming any of those abiding by the oaths, nor shall I take any city or fortress nor harbor by craft or contrivance with intent of war against the participants of the war, nor shall I depose the kingship of Philip or his descendants, nor the constitutions existing in each state when they swore the oaths of the peace, nor shall I do anything contrary to these agreements, nor shall I allow anyone else as far as possible. But if anyone does commit any breach of the treaty, I shall go in support as called by those who need, and I shall fight the transgressors of the common peace, as decided by the council and called on by the hegemon, who is, when the oath is made, who is Philip of Macedonia.
