Rulers can enforce realm peace to force all vassals to end their wars. It is often used to prevent vassals from growing too powerful, or to enable changes to succession law.
Vassals can use favors to request that the council votes on realm peace. Vassals can also use favors to block use of realm peace for a few years.
Requirements
御前会议DLC- The council must be empowered to vote on laws
- The council must be content (no recent succession or tyrannical bypassing of the council)
- The council must vote to approve enforcement (the ruler cannot bypass the council for tyranny on realm peace votes)
- Realm Peace was not started within the last 10 years (5 years of enforced peace followed by 5 years of cooldown)
效果
经过四个月的等待期，封臣之间的一切战争都会无条件和平（并非一定！）.
五年内，直属封臣不能互相宣战。此外，“附庸的附庸”不能发出派系的最后通牒，因为这也会导致内部战争。
对于正在发动内部战争的封臣，会受到严厉的好感惩罚。[可能只有进攻者]. 好感度显示为“-40 暴君”，但只适用于少数附庸，而不是所有，如暴政。
Alternatives
If you can't or don't want to enforce Realm Peace for the entire realm, you can use other methods to intervene in specific wars between vassals.
- Pass laws prohibiting wars between vassals, with Imperial Administration
- Demand Peace interaction, with
The Reaper's Due - Revoke titles from one participant to weaken or even unland them
- Grant titles to one participant to strengthen them
- Force one of them to rebel against you, perhaps by excommunicating and arresting them
- Invalidate their CB by e.g. assassinating the claimant in a Claim war
