Medism
Medism (Greek: μηδισμός, medismos) in ancient Greece referred to the act of imitating, sympathizing with, collaborating with, or siding with the Persians. While the term "Mede" was commonly used by Greeks to refer to the Persians, strictly speaking, the Medes were a distinct Iranian people who were co-rulers with the Persians in the Medo-Persian (Achaemenid) Empire.
