Though Assurbanipal doesn't really translate to 'king of the world' (see my comment below), the title in Akkadian is actually 'shar mātāti,' which is all the more striking. I haven't been able to find whether Akkadian shar shares a common root with Persian shah, although the ancient Achaemenid Persian empire did consciously model itself on a friendlier, ecumenical Assyrian model.
