But Meissen should be a lot bigger than Merseburg, Merseburg was mainly just the city itself
I have use the same map you can see in this article. And I have give them a part of the Osterland. Or for a better look here.. One map of 1200 and one map of 1000. So I use Merseburg ans Zeitz as followers of the marches.
I concur, but would it not be better to make it into a entity that could work also with the Oborites? I personally made a county of Wargrien and tied it to Lübeck
Okay... I make it to Wargrien. And rename it after it became part of the HRE and/or Denmark. So okay?
But as you said before, ~8 provinces is the best number... So I think it needs to stay like that. Of course Olesnica is pleased to be added. I was also thinking about Oswiecim, but I wasn't sure about this (if not as Silesia, then maybe Lesser Poland).
Oswiecim is possible, yes.
