How To Join A Kingdom In Mount & Blade II BannerlordYou might have to complete the main mission “Rebuild your Clan” to gain enough influence to join a kingdom. If you want to join a kingdom, find a castle in the area and speak to the lord inside. If there is no lord, try a different castle. When you get to a castle lord, tell him that you wish to fight for the kingdom. They will offer you a mercenary contract and pay you for each battle you win in their favor.
This also allows you to join up on armies in the area that are of the same faction. You can join a kingdom mid war and follow the army around netting you good exp, loot, and prisoners. Be wary of raiding villages though, sometimes your companion members get whiny about it. Killing the garrison is fine, its looting after you have beaten them that gets your companions upset.
When you join a kingdom you also take on the enemies of that kingdom. So if they are at war, you also join that war. This means you will be hunted if you are in the enemies lands and you cannot use the villages/shops anymore in the enemy area. If you click onto an allies army, you can join up with them and follow them around. It does still take your food, and the allies will take food if they are starving, but moving as a large unit means more protection. You can also donate troops to the garrisons of castles in the kingdom you have joined.
