And so you could imagine the Athenians now are starting to take significant offense to how the Spartans are treating them. And then you fast forward a little bit more to 459 BCE, and you have two allies of Sparta, Megara and Corinth, and they're right in this very strategic location, that little land, that land connection, that land bridge between the mainland and the Peloponnese. And there is a dispute between these two allies of Sparta, between Corinth and Megara, and Athens decides to intervene and form an alliance with Megara. Well, you could imagine, you know, this insecurity has been building up in Sparta for, at this point, over a decade. And so it all comes to head, and they start having skirmishes, and they start essentially going to war with each other. They have these sporadic skirmishes over the next 15 years. And this period, right over here, from roughly 460 or 459 for the next 15 years, this is often referred to as the First Peloponnesian War, because, once again, you have Sparta and its allies starting to get into all of these skirmishes with Athens and its allies.
