The Rim Worlds Republic and Marian Hegemony’s foundations are similar enough to the rest of the Periphery. Both tried to emulate the ancient world, in the Republic’s case it was Greece, the Hegemony favoured Rome. Both set out an aggressive expansion policy from the outset, conquering nearby Periphery States. But as the Republic matured, they changed their basis from Ancient Greece to Napoleonic France. It remains to be seen what the Hegemony will do. It should also be said that they are, geographically, mirrors of each other. The Republic’s power base was on Apollo, out near the top of the map, and gradually stretched all the way to Circinus. The Hegemony’s base is on Alpheratz, out near the bottom, and was, up to the Jihad, stretching ever closer towards Circinus. The difference is scale and depth. The Republic was composed of hundreds of worlds, and lasted for centuries. The Hegemony are only dozens of worlds, and have lasted decades.
