Hi - I'm playing Poland in a 1444 start ironman game, I managed to add Krakow to the HRE near the game start, and as it's my capital, Poland joined the HRE and so I get the benefit of -10% Tech/Stability costs etc. No other Polish provinces are in the HRE. I've now diplo-annexed Masovia - if I move my capital to Warsaw, will I have to leave the HRE? My relations with Austria now suck and my relations with the electors are not good enough (yet) to become Emperor myself, so I won't be able to add Warsaw to the HRE for while. If this would result in me leaving the HRE, I think I would be better leaving my capital in Krakow, to benefit from the HRE tech bonuses, until I can become Emperor. NB: I intend to stay Eastern Tech.
