From the Persian perspective, such terms would not be so humiliating as they might at first seem. The Persians already allowed the Greek cities of Asia to be governed under their own laws (under the reorganization conducted by Artaphernes, following the Ionian Revolt). By these terms, the Ionians were still Persian subjects, as they had been. Furthermore, Athens had already demonstrated their superiority at sea at the Eurymedon and Salamis-in-Cyprus, so any legal limitations for the Persian fleet were nothing more than "de jure" recognition of military realities. In exchange for limiting the movement of Persian troops in one region of the realm, Artaxerxes secured a promise from the Athenians to stay out of his entire realm.
