I wasn't trying to be insulting Tom, but as someone else pointed it out, it's not *that* clear. Unrest could mean any of the following: Low region control, low morale, low loyalty or any combination of the three. War could mean battles but it could also mean looting or a takeover in progress. If you intend for it to be explicit about the cause then make it explicit. E.g:
"You can not move your capital because a battle was fought there recently".
You still didn't read it properly. Look, if it means "because of a recent battle", wouldn't it say so?
It does mean war or unrest. In this case, I'm pretty sure the daily looting I put in keeps the capital as not peaceful. However, I just realize thanks to this discussion that a realm under pressure should be able to move its capital even under these conditions, but at a penalty. I will add that.
