What the factors for the AI when deciding tributary wars? I'm playing a vassal in scotland and my liege was declared war on by a king of England, and when I seized the the throne the old scottish king who was now my vassal was still processed as being a tribute of england, so I revoked all of his titles and not too long after the very same English king that had attacked before now attacked me for a tributary status, and since England is pretty OP in 1066 I had to surrender. Are certain characters more likely to declare tributary wars than others? How can I prevent tributary wars against me? Note: This king of england had about a 48 opinion of me and that usually would keep me safe for a while but not with him for some reason.
