Novgorod / Russia

[Ludens]

I guess my advice was not so sound after all. It sounds like a tactical retreat would have been better. You should not weaken yourself fighting rebels if the Almohads look so powerfull. Perhaps you can still do that. Leave the priests in place (as you want those provinces to be Orthodox whether you or the Almohads occupy them), but consider withdrawing your spies, as they are at great risk when the Almohads capture or build borderforts.

I guess I can explain how this happened, as a rebelling province tends to drag nearby provinces into rebellion as well. To prevent this, it often advisable to keep loyalty at 120%. I don't know how one single defeat could cause such chaos, but perhaps your king has low influence. In which case: check your generals' loyalty because a civil war might be brewing. Retreating then is not an option, because it will decrease your influence even more. All you can do then is attack and hope to take out the rebels without losing too many valuable men.

Edit: could it be that one of your ship lines has been severed by the presence of enemy ships? This often causes the characteristic rebellions and the drop in income you describe.
