An alliance is an agreement between two rulers that they can call upon or join each other's wars via a character interaction. Declaring war on an ally will add -25 Popular Opinion for 3 years.
建立同盟
已结婚的两个角色之间会自动创建一个同盟，并且当两个统治者的两个近亲家庭成员已婚或已订婚时，也会自动创建一个同盟。 在结婚提议界面上可以查看结婚提议是否会导致结盟。 此外，如果满足以下要求之一，则两个统治者可以协商联盟：
- Both rulers are at least 3rd degree relatives
- 其中一位统治者解锁外交生活方式的技能自卫谈判
同盟的接受度取决于两个统治者的主头衔差距，军事力量以及彼此之间的好感
Opinion。 此外，接受还可能受到以下因素的影响：
| Source | Acceptance |
|---|---|
| Terrified | +100 |
| Intimidated | +50 |
| Vassal | +40 |
| Claims | +25 |
| Same House | +15 |
| Heir | +10 |
| Source | Acceptance |
|---|---|
| Rival | -100 |
| Evil Faith | -80 |
| Hostile Faith | -60 |
| At War | -50 |
| Astray Faith | -40 |
| Different Faith | -20 |
A proposed Alliance can be accepted by using a Hook, either Weak or Strong.
加入战争
When a character is at war, each one of their allies will have the option to join the war via the Offer to Join War character interaction, which the targeted character will always accept. Alternatively, a character who is at war will have the option to ask their allies to join a war via the Call to War character interaction. The acceptance is determined by the character's Opinion, modified by the following:
| Source | Acceptance |
|---|---|
| Heir | always |
| Spouse | always |
| Defensive War | +50 |
| Defensive War against their Ally | -25 |
| Offensive War against their Ally | -50 |
| Enemy is Heir | never |
| Enemy is Spouse | never |
召集盟友加入防御性战争没有威望花费。但是，在进攻性战争中，将根据盟友的等级花费一定威望：
| 等级 | 花费（ 威望）
|
|---|---|
 男爵 |
750[1] |
 伯爵 |
75 |
 公爵 |
150 |
 国王 |
350 |
 皇帝 |
750 |
Allies declining a call to war invitation will suffer an opinion penalty with their ally ( -10 for one year for offensive wars; -20 for three years for defensive wars).
结束同盟
当“建立同盟”中列举的要求不再满足时同盟会立刻终止。正在进行的战争并不会受到影响。
