You have many of the city states that were part of this Athenian Empire, they're starting to revolt. You can imagine that the Spartans are trying to help those revolts, because they're trying to get the Athenians wherever they are. This is often also called the Decellian, or Decellian, Decellian War. Decellia, or Decellia, I'm probably not pronouncing well, is a little village right over here at the top of Attica, and it was a strategic location that went over to the Spartans, and that's where the Decellian War gets its name. But over the course of this third phase, the Spartans get help from the Persians. Remember, this was their enemy. They had, the Spartans and Athenians had unified against the Persians, but some time has passed.
