In the Greco-Roman world, Ariana was a geographical term referring to a general area of land between Central Asia and the Indus River. Situated far to the east in the Achaemenid Empire, it covered a number of satrapies spanning what is today the entirety of Afghanistan, the easternmost parts of Iran, and the westernmost parts of Pakistan. "Ariana" is Latinized from Greek: Ἀρ(ε)ιανή Ar(e)ianē [region]; Ἀρ(ε)ιανοί Ar(e)ianoi [demonym]. The Greek word, in turn, is derived from the term Airyanem (lit. 'Land of the Aryans') in Avestan. .
