Also, unrest is max 500. I know, my capitol has it in Discharge.
But what really annoys people up is a huge van army sitting in their lands, grabbing 15-ish provinces in one turn, then moving out with taxes at 200 to siege all the castles they can horde to. Add in a friendly neighbor of Helheim who's doing the same at exactly the same time to the same target, and you've got a nice economic crumble in one turn.
