With the fall of Nineveh, the Empire was split in two, the western half falling in the hands of a Chaldean dynasty, the eastern one in the hands of Median kings. In 539 BC, both became incorporated in the Achaemenid Empire, the western one as the megasatrapy of Assyria (AӨūra), the eastern one as the satrapy of Media (Māda).
