So I thought I'd have a go at Poland for the first time just by conquering Mazovia to see how playing Poland was like. However I'm on a roll now and I'm really enjoying this Poland game. I wanted have good relations with the Empire next to me, so I joined my provinces into the HRE, I still have a PU with Lithuania and a PU with Bohemia just came out of the blue just by having a RM with them which was a very nice surprise.
I now have good relations with all the electors and it now seems likely that I will become the next Holy Roman Emperor, snatching the title from Burgandy. I'd like to form/unite the HRE, however I have no experience with being the emperor before, so do any of you have any hints and tips on being the Emperor and getting good imperial authority?
Thanks for the any help.
