Right, well I'm the sovereign ruler of the territories of the Khegit Khanate and the Sarranid Sultanate, with 99 right to rule and a whole mess of lords at my disposal. The war with the Sarranid's recently finished and we've been at peace for about a month or so. So I decided it's time to push my claims for the throne of Caladria and deal with the Rhodocks. So I go to my minister and tell him to declare war on the Rhodocks. I take an absolutely massive hit to my honor (like 25 or so) and lose a metric ton of reputation among my lords. Ok, so I started a war without provocation. I load back (yes, I don't play it on realistic, so sue me), and go attack a caravan instead. The same thing happens. I tried attacking a lord of that faction...same deal.
So does anyone know of any way to start a war without all my lords hating me and losing a quarter of my honor? Because I'm too big, too powerful and have too much right to rule to hope that someone else will declare war onto me...
