Did Portugal really have a different foreign policy then Spain though in the early era?
Also for late ages I have a suggestion, rename Kievan Rus' to just Rus' or something along those lines, it will be more realistic, nobody ever really called Rus' states Kievan, Novgorodian, Suzdal untill 19th century really, which was back then for Russian propaganda, in fact Russian Wikipedia recently already changed Kievan Rus name to something like Old Rus' State or OldRussian State, there was a large debate on it, however In chronicles they just called it Rus' or Rossiya, Ruthenia or Russia - it's all same thing in different languages. It's actually even a stretch to have Novgorod and Kievan Rus' as different nations, the Novgorodians had their own system of administrative ruling but it was always other places Rus' princes they chose for foreign relations, so they were really subordinate to the Kievan Rus' or Old Rus' State, for example the famous Alexander Nevsky, he was actually from Vladimir Suzdal, ruled Novgorod, Kiev and Suzdal at different times. He like many others was summoned by Novgorodians. It is because of the complicated mess of early feudalism in the state. The principality states fought against each other but when there was a foreign enemy and Rus' was at risk they always united, it's maybe something of a unique system and that's why it's hard to portray...
So in a way the original Medieval 2 was actually more correct then any other just calling the whole state "Russia" with starting as a Boyar in one of the principalities and fight for more power in the main campaign, but the rebel Rus' cities were a bit wrongly portrayed as the whole Rus' would not allow other countries such as Poland or Lithuania to just take a principality so easily, this would only be allowed in infighting between boyars...
In the early ages this is not of a big problem as Rus' was a more or less united state like in the map shown but I would be glad if someone tried to portray a more realistic Rus' like aforementioned in the late ages.
So maybe the mapper can add to this or explain of having both Novgorod and Kievan Rus'? Is there maybe a similar situation somewhere in west Europe so we could copy solution to Rus'?
What is their opinion, I'm just interested from historical perspective, I don't think it's too big issue though if you guys want to leave it as I'm not even sure myself how to realistically portray the states of East Slavs at that time, I just put whatever information I know here as a Kievan myself..
