Roman Oligarchy Division

A follow up of my Mirror Universe. This shows the internal divisions of the Roman Oligarchy. Unlike my previous map of the Teutonic Empire's divisions, this isn't so much about population, but actual borders between the internal polities. The Oligarchy is a federal state composed of five kingdoms: Portugal (purple), Spain (red), France (blue), Italy (green), and Romania (yellow). The unpictured possessions in West Antarctica are Spanish.
Romania has no colonial possessions, as they can only send out ships into the Black Sea and the Greeks won't let them into the Mediterranean. The Italians have promised that when they conquer the Confederacy they'll give that territory to the Romanians, but the sincerity in this dubious.
EDIT: Now with 400% more semi-autonomous duchies: Catalonia, Occitania, Sardinia, and Dalmatia.
