I thought I was safe from this with the imperial crown to hold it all together in the same way a King can hold dukes together after inheritance. Just tired of fighting unification wars. All the kings are pretty loyal to me since they just got their crowns. or is it because I didn't make enough crowns for the empire?
I handed out the titles for Vladimir, Novgorod, and Lithuania, created Ruthenia and kept it. i have the lands for Estonia and Chernigov but didn't have the money.
