Bohemia views Brandenburg as their suzerain overlord.
Lüneburg views Brandenburg as their suzerain overlord.
Pommerania views Brandenburg as their suzerain overlord.
Personal Union wiht Bohemia was planned, albeit keeping me from becoming the emperor. Vassalizing Pommerania is a strategic stepping-stone in forming Preußen. Lüneburg just triggered a personal union on me, provoking a was with Austria. Not planned.
I am bleeding diplomatic power because of this, and still have to deal with what remain of the Teutonic Order. I suppose full annexation of them and then transfer their provinces to Pommerania is my only way forward.
Not touching the Hansa until after the Preußian lands are well integrated. Not voluntarily anyway. #eu4
