Barely shown is the Imperial Africa and Imperial South America, the first stretching from shown on the picture down to Kongo and including the Cape and Madagascar. Imperial South America stretches from Honduras to Uruguay, stopped slightly by Castillan holdings on the tip of Brazil.
Milan>Italy>Holy Roman Empire in 202 years, this pic taken shortly after unification. I've played 50 years more which has among other things lead to:
*Personal Unions with Flanders and Castille
*Land gains in Iberia (northen tip of Aragon to the lone Aragon province in the south), France(everything directly south of Burbonnaise as well as Normandy with provinces connecting it to the main empire), Austria (Ruthenia and Sopron) and Greece (the currently castillan parts)
*Divisions of other powers, France is now only Paris and three colonies in South America and several more small french states have popped up, Aragon is an OPM, Styria, Hungary and Poland have been released from Austria, Sweden has lost a couple of states in Russia and Jylland is again Danish, but still have a fairly extended Empire.
*My vassal Venice, still free on this map, has been annexed peacefully.
*My vassals are Denmark, Styria, Bosnia and Serbia as well as some french states I can't remember.
*Allies are Tunisia, some other French states (there's 8 or so of them), Zapotec (liberated from France) Teutonic Order, Danzig (the green south of my Kurland/Livland holdings and directly east of TO Riga)
*Great Britain are in a PU with Brittany and has the one province on the coast directly south of it, they're interfering with my sphere of influence...
My goal is now to re-conquer the Roman Empire, starting in the west. For legitimacy reasons I plan on entering a PU with Byzantium, I'm currently charming them, but I might need to speed things along, so some "obscure claims" might be needed (what do you mean obscure? I'm the Holy Roman Emperor, they are technically the "Roman Empire" it's nothing 'obscure' about that!)
