Well then since you asked so very nicely, there are a variety of answers none of which are more than likely going to answer your questions since I don't know every factor of increasing unrest.

1. An enemy is using a spy against you in some way on multiple provinces.

2. You haven't found all the sites and a few are causing Unrest. Have you Acashic Record cast on all these provinces?

3. Opposing dominion in provinces controlled by you creates unrest.

4. Stealth armies cause unrest (I don't know) and there are stealth armies running through your lands.

5. Global Enchantments are causing unrest.

6. You are not killing your unrest all the way. Unrest produces more unrest and scales upward if you leave it unchecked.


Try leaving the opponents dominion on your provinces, killing all the unrest by turning your tax to 0% until it's all gone, then turn it to 100% and see if it rises, if it rises in only places with opponents dominion, then you might have your answer. If it raises in other places, try casting an Acashic Record on it to see if there are any stealth sites causing unrest, or send over a crew to patrol and try to catch any spies/bards.

Besides that, you'll have to figure it out. I've had unrest problems in my domains before, but never to the extent you apparently have.
