We have not chosen factions on the basis of complete autonomy, because that would be too restrictive a system to properly simulate the complex factional structures of 11th century Eurasia, instead we have gone for de facto autonomy. Bohemia, Tuscany and Lombardy all recognised the Holy Roman Emperor as their de jure overlord, but were all considered simply autonomies bodies within a larger body. Indeed, by the end and especially after the end of this mod's time-line, the various factions within the HRE became more and more de facto autonomous. Historians today are still perplexed by the fact that somehow the system actually functioned. Those three factions I mentioned, were by the start of our mod almost fully autonomous however, and were starting to become major players in their own right with their theatres and remained such for a long period with our mod's time frame. That is why we have chosen those three to be specific factions separate from the larger body of the HRE that they belonged to de jure: they were very important players within their theatres (Eastern Europe and Italy), and without them those theatres would have, in our opinion, a great void, there would be too little competition, too little division of power. The choices as such have been made both to accommodate historical accuracy (i.e. the factions being de facto autonomous historically) as well as interesting gameplay.
