Now with that said, you might say, well, why did the Greeks call it Persia? Well, the Persian Empire, what we consider to be the first true Persian Empire, is the Achaemenid Empire. And we'll talk in a second why do we call it even the Achaemenid. But the Achaemenid Empire emerges from a region of Persia, I guess we can say, that in this map is referred to as Persis, but other names for it are Pars and even in modern Iran, there is a region called Fars which coincides very close with it. And since the leaders of the Persian Empire and especially Cyrus the Great emerged from this region, they called them the Persians and it was the Persian Empire that emerges from this region, what you might wanna call Pars, Fars. Fars especially comes from Arabic where they don't have the P sound, but Pars or Persis or whatever you wanna call it and that's why it was called the Persian Empire. Now, it wasn't the first empire in that region.
