So there's, based on my research, ideas like Aryanum Veja and Aran Shah and Aran. So it actually turns out that the modern, the name of the country, the modern word Iran, is probably more appropriate or in some ways closer to what the region has always called itself, what the Iranians or the Persians have always called themselves and called where they lived. They referred to themselves as the Aryans and where they lived as the Aryanum Veja or Aran or Aran Shah or some version of that in the modern version is Iran. 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.
