Median kingdom
Media (Old Persian: 𐎶𐎠𐎭, romanized: Māda; Ancient Greek: Μηδία, romanized: Mēdía; Akkadian: Mādāya) was a polity centered in Ecbatana that existed from the 7th century BCE until the mid-6th century BCE, and is believed to have dominated a significant portion of the Iranian plateau, preceding the powerful Achaemenid Empire. The frequent interference in the Zagros Mountains by the Neo-Assyrian Empire, located in Upper Mesopotamia, led to the unification of the Median tribes.
