War and combat are regular performances in Mount and Blade II: Bannerlord, and you will find yourself combating at least one of the various powerful factions in the game. You may find yourself declaring war against them, and if you do, eventually, you may need to regroup to recover your forces and resupply your armies. The best way to do this is by making peace, which is an essential focus of any war.
At this time, the standard method to declare peace with another faction, much like declaring war against them, is displayed. Right now, it’s grey when you view it in the Kingdom menu. However, you can antagonize another faction enough times by raiding their villages and caravans, provoking them into initiating a war against you.
For those who want to work out peace with a warring faction, you do have an alternative. You need to seek out one of the leaders of the warring faction to speak with them. Upon approaching them, you have the option to speak about finding peace between the two of you. You can view who is a leader in a faction by checking it in your encyclopedia and hitting the left-alt key while wandering around the map. You want to locate armies with distinct names underneath them.
Unfortunately, it’s not as simple as swaying them to understand you want to form peace. You need to barter with them. How much you need to bargain will vary. Sometimes, the price for peace is a bit too high, so you may have some difficulty trying to make it happen.
When you do come to an arrangement, you will find that the faction’s villages, strongholds, and armies no longer have a red outline around them. You won’t have to worry about combating them moving forward unless you do something to oppose them directly.
In future updates for Bannerlord making peace should be substantially easier. You’ll be able to reach out to a warring faction by referencing it in the Kingdom tab, but the process may work the same where you need to barter to make it happen.
