As an endgame tag in an unofficial 'fourth tier' - even other tier 3 formables can create it, if they meet the requirements - it has the most stringent requirements but the greatest rewards of any formable nation in the game. Its Diadochi successor states of Antigonid Kingdom, Seleukid Empire, Egypt, Macedon, and Thrace are the best positioned to reform the empire, but the Argead Empire can potentially be created by any Hellenistic culture group monarchy.

The Hellenistic Empire is a formable nation representing the restoration of the Empire of Alexander the Great that had fallen apart some years before the start of the game.
