no, i'm talking about something similar to native and the pretender rulers (can't think of that word). you could in turn help them regain a region and make them king and in turn you get a huge thank you.
peasant revolts don't lead to anything, lots of death, lords armies destroyed but no new factions or emergent ones.
again every "suggestion" i can think of is not worth the effort until maybe past the final release.
You should do the Taleworlds approach, release a playable version and then add stuff on.

I'm joking ofcourse
