And you also can't raid "within a realm" in the current system. That would be funny tho, imagine if you had to have higher than 0 crown authority to stop raiding within the realm....
Yeah but I think you should, as you say under low crown authority. Anytime you see references about the Public peace in history it’s referring less to stopping what would have been considered “legitimate claim wars” and more about stopping the incessant inter-baronial raiding and pillaging that was ripping the countryside apart and turning it into a living hell for the peasantry and burghers.
This usually happened during low points of central authority. Examples being England during the Anarchy, the Rhine during the various periods of Robber Barons, and was the general state of France (particularly around Ile-de-France) in the 10th to 12th centuries.
To highlight this mindset, allow me to post a quote from Bertrand de Borne a petty Nobleman and troubadour of the 12th century:
“"We are going to have some fun. For the barons will make much of us ... and if they want us to remain with them, they will give us barbarins' (i.e. coin of Limoges). And again: 'Trumpet, drums, flags and pennons, standards and horses white and black—that is what we shall shortly see. And it will be a happy day; for we shall seize the usurers' goods, and no more shall beasts of burden pass along the highways by day in complete safety; nor shall the burgess journey without fear, nor the merchant on his way to France; but the man who is full of courage shall be rich.'”
This is the kind of Roleplay that I want to see in CK
