Persia: Achaemenids to Sasanians
Cyrus the Great and the Achaemenid empire, the Cyrus Cylinder, Darius I's satrapies, coinage and the Royal Road, Persepolis, Zoroastrianism, the wars with Greece, Alexander's conquest, the Seleucids and Parthians, the Sasanian revival and wars with Rome, and the Arab conquest.
Empire by administration
The Achaemenids governed a vast, diverse empire largely through local elites, tribute and roads rather than imposing one culture; Aramaic served as a common administrative language. Greek sources, especially Herodotus, shape Western views of Persia as the enemy of Greek freedom; Persian inscriptions such as Darius's at Behistun present the kings in their own words.
