Each country has an opinion of every other country that they know of, expressed as a numerical value, which ranges from -200 to +200, and a descriptive attitude, which indicates an overall "mood" and general intentions. A country's Relations with another determine how likely it is to hurt or help them, such as entering agreements with them or joining coalitions against them. Relations are shaped by diplomatic actions, the countries' relative power, their proximity, recent wars, religion, casus belli and events. As such, how country A views country B is sometimes very different than how country B views country A.

态度

The player can learn about another nation's view of their nation by hovering over the small symbol in the diplomacy screen next to the numerical representation of their view of the player's nation. Attitudes are affected by a number of factors, including opinion level, aggressive expansion, the distance between two countries and whether they border, and their relative military strengths. For example, a nation usually will not have the outraged attitude towards a nation it has a positive opinion of.

The attitude of a nation affects its willingness to accept diplomatic proposals, manifesting as modifiers that affect the decision of AI nations during diplomacy. For example, nations with the hostile attitude will almost never agree to an alliance even if mutual opinions are positive.

  • Neutral attitude Neutral: This is the default attitude for nations far away from the player's. If a nation views the player as neutral, war can happen under certain circumstances, however, a good relationship with these nations can often prevent this.
  • Hostile attitude Hostile: This nation wants to fight the player, either to conquer land or break free from them. Unlike rivalry or outraged, this attitude is more opportunistic, and the nation may switch to another attitude if the player no longer appears as an appealing target. Growing in military strength or improving mutual opinions may change this attitude.
  • Rivalry attitude Rivalry: If a nation sees the player as their rival, they will want to destroy the player and will be very unlikely to change their opinion. In contrast to someone who is outraged or simply in a military alliance against the player, a rival will be the player's enemy for the foreseeable future. A nation will stop being a rival if it becomes either far weaker or far stronger than the player's nation.
  • Outraged attitude Outraged: If a nation is outraged by the player's behaviour, they will actively seek to destroy the player. These nations are an enemy and will be so as long as the reasons for the outrage are present. They will very likely join a coalition against the player. Then they will revert to their "normal" view of the player. This attitude is linked to a high aggressive expansion modifier towards the player's nation and will change if aggressive expansion decreases.
  • Defensive attitude Defensive: This nation views the player as an ally in a defensive alliance. They are less likely to join offensive wars, however, unless they strongly dislike the target (especially if they're rivals).
  • Friendly attitude Friendly: This nation views the player as a natural ally. They will not declare war on the player, and are unlikely to join their allies in a war against the player as long the diplomatic landscape doesn't change significantly, even if relations are bad. These nations will seek to ally with the player. Nations that regard the player as a historical friend are predisposed to hold the friendly attitude towards the player.
  • Protective attitude Protective: This nation wants to guard the player's nation—by diplomatically vassalizing them. It will guarantee the player's nation and defend it from enemies, easily accepting alliances though possibly as a prelude to vassalization, but also usually refusing to partake in any offensive wars.
  • Loyal attitude Loyal: This subject nation views the player positively, has low Liberty desire.png liberty desire, and will cooperate in times of war and be little inclined to declare independence.
  • Disloyal attitude Disloyal: This subject nation views the player negatively or with hostility, has high liberty desire, and will refuse to defend the player's land or pay taxes, and be more inclined to declare independence.
  • Rebellious attitude Rebellious: This subject nation views the player as weak and unjust, and will be very likely to declare an independence war.
  • Overlord attitude Overlord: This country views the player as one of its subjects.
  • Domineering attitude Domineering: This nation feels like the player should be its subject nation, and will pursue any attempt to make it that way.
  • Threatened attitude Threatened: If a nation feels threatened by the player they will seek safety in an alliance either against or with the player. This happens when the player is becoming relatively stronger than them. Here it is better to ally with them, because even though they fear the player they will often be ready to fight with them in a defensive war. However, they are still the player's enemy and will break the alliance as soon as the power landscape changes.
  • Unknown attitude Unknown: The nation doesn't know the player's exists, or else the nation is human-controlled and thus unpredictable.

侵略扩张

侵略扩张(Aggressive Expansion)是模拟侵略行为对其它国家负面外交影响的机制,主要由吞并省份和强制附庸带来。

如果外交关系中有侵略扩张的负面影响,它会显示在详细的关系视图中。

当签订合约时,侵略扩张合计超过50的国家会被列出,这些国家可能会加入针对玩家的包围网。

产生

  • 吞并省份:-0.75/发展度
  • 威胁战争:-1/发展度
  • 附庸: -0.5/发展度
  • 联统: -0.1/发展度
  • 割让殖民地:-0.25/发展度
  • 保护国: -0.25/发展度
  • 撤销选帝侯:-25
  • 宣战时降低稳定:-10/稳定
  • 附庸行动: 宗主国获得附庸产生的全部侵略扩张(包括保护国,朝贡国除外)

省份超过30发展度的部分不计入侵略扩张

影响

  • 侵略扩张惩罚会减少外交关系 。 这个负面修正会以基础+2每年的速度衰退,衰退速度受改善关系修正。
  • 当侵略扩张超过-50,且外交关系为负时,对本国的态度 会变为愤怒的
  • 当侵略扩张超过-50时,且不在战争中或停战期,可能会加入对本国的包围网。There should be at least 4 nations with -50 aggressive expansion modifier and negative (below 0) opinion about you, in order for coalition to form. If there are 3 such countries, or one of them has positive opinion, it will not form.

如果你的国家是天主教,成为教廷控制者会使Aggressive expansion impact.png侵略扩张减少-20%

以上各项修正叠加,可以在国家修正中看到最终数值。

宣战理由
  • 征服省份: *100%(即宣称,1.16由75%变为100%)
  • 收复核心: *25%
  • 开除教籍: *50%
  • 宗教战争: *75%
  • 帝国主义: *75%
  • 民族主义: *50%

宣战理由只对它的目标省份有效。如收复核心只对有核心的省份AE*25%,其它省份仍然*100%

其它叠乘修正
  • 割取'非联合作战' 国家土地,侵略扩张 * 150%
  • 行政效率

侵略扩张还需乘以行政效率,吃100过扩产生的侵略扩张总是相同的,不论行政效率是多少。

  • 防守方减成 *75%

当进攻方宣战理不是相互的,防守方议和产生的侵略扩张乘以75%

非相互的战争理由包括征服省份、收复核心等,在防御这种战争时割地,有额外*75%的侵略扩张减成

相互的战争理由包括宗教战争、帝国主义、民族主义等,他们的防御割地与宣战理由享有同样的侵略扩张减成,不再享有重复的防守方减成

传播修正

侵略扩张产生后,从产生地向外传播到各国。定义几个名词:

进攻国——发动战争和割取省份的国家

防御国——被割取省份的国家

目标国——产生侵略扩张的国家,计算距离的终点

如果进攻国未发现目标国,不产生侵略扩张(视野外的国家不产生侵略扩张)

以下叠加型修正,取决于防御国国家与目标国的关系

叠加型
  • 同文化组国家 +25%
  • 同一文化国家 +50%
  • 不同宗教组 国家-50%
  • 同宗教组 (异端)国家+0%
  • 同一宗教国家+50%
    • 满足上一条的基础上, 如果进攻国不同宗教组 +50%.
  • 神圣罗马帝国成员 +50%
  • 有同一个宗主国+50%

割地时,文化是比较被割让省份文化与目标国主流文化。强宣时,比较防御国首都文化与目标国主流文化。

宗教的判定,只看防御国和目标国的国家信仰,与省份信仰无关。

同一个宗主国,意思是你割某个国家附庸的地/强宣某国附庸,那么产生的AE对这个国家的附庸+50%

距离修正

侵略扩张的传播距离,是侵略扩张产生省份到目标国边界的距离。其计算方法与边界距离(Border distance)一致。

  • 传播距离<=100 无距离衰减
  • 100<传播距离<=200 *0.75^2=56%
  • 200<传播距离<=300 *0.75^3=42%
  • 300<传播距离<=400 *0.75^4=32%
  • 400<传播距离 *0.75^5=24%

侵略扩张产生省份就是被割取省份,每个省份分别计算距离。强制宣战时,被宣战国家首都是起点。

两个国家之间的边界距离,是两个国家距离最近的核心省份之间的距离,这个距离可以在debug_mode中看到。(边界距离的计算包括附庸)

距离估算方法:外交官每天在两个国家首都间行走20距离,可以通过天数计算首都间距离

同盟减成
  • 同盟联统国产生66.7%的侵略扩张
  • 附庸国(包括朝贡国)产生10%的侵略扩张

衰减

  • 侵略扩张惩罚以基础+2每年的速度衰退,衰退速度受改善关系修正,在每年1月1日生效
  • 和谈时解放国家/割让省份或归还核心给敌方阵营 -0.375/发展度
  • 和谈时取消附庸/联统国 -0.25/发展度

以上两个侵略扩张衰减不受任何修正,全球所有国家都减一样的侵略扩张

边境摩擦

Border friction simulates the tensions felt by countries with neighbouring territories, due to migration, land rights etc.

历史盟友与宿敌

Historical friends and historical rivals are pre-set by the scenario's starting conditions, and do not change over time. These modifiers don't only affect relations by giving −25 or +25 bonus.

Historical rivals will almost always rival each other and if that's no longer possible, they will never make an alliance. If historical rival country is a vassal or lesser partner in personal union, it will have +50% liberty desire modifier. For example: Oirat and their vassal Mongolia, Denmark and Sweden after The Scandinavian Constitution event.

Historical friends on the contrary will gladly and often make alliance with each other. If historical friend become a vassal or lesser partner in personal union, it will have -50% liberty desire, which makes this relation very stable. A good example for this is Polish-Lithuanian union. Historical friendship can be removed by Growing Animosity event, that can occure when historical friends are fighting each other.

List of historical friends in 1444:

  • Austria – Hungary
  • Bosnia – Serbia
  • Denmark – Norway
  • Lübeck - Bremen
  • Lübeck - Hamburg
  • Poland – Lithuania
  • Portugal – Castille
  • Riga - Lübeck
  • Riga – Livonian Order
  • Teutonic Order – Livonian Order
  • Venice – The Knights

改善关系

There are several diplomatic actions available if a country want to improve relations with another country.

  • Improve Relations action is the most direct way. A country can get up to +100 relation points with another country. It takes time and ties down a diplomat.
  • Send Gift will get a country up to +25 relation points for a one-time gift of money. The relation bonus will last for 5 years, effects from several gifts do not add up, only the last gift will affect relations.
  • Give Subsidies will transfer a specified amount of money each month to the target country for a certain duration. Maintaining subsidies will improve the target country's relations with the subsidizer each month, up to a maximum of +15. This will disappear entirely once subsidies stop, unlike Improve Relations which ticks down over time.
  • Offer Military Access to the target country, allowing their land armies to pass through the territory of the one who offered. Acceptance will raise the target country's opinion of the offering country by +10.
  • Transfer Trade Power ask a target non-subject nation to transfer a percentage of its trade power to the requester. Grants a mutual relation bonus of +20 per 100% of power transferred. (only with Wealth of Nations.png Wealth of Nations enabled)
  • Influence Nation gives +25 with the target country for one time their yearly income, if you are Great power and the target nation is not. Lasts for 10 years and for that duration the target country receives a monarch point on whatever category it has the lowest influx of. (only with Rights of Man.png Rights of Man enabled)
  • Take on foreign debt improves relations by +10 for every loan of debt the target country has that you take over. Requires being a Great power while the target is not.. (only with Rights of Man.png Rights of Man enabled)

The following actions will tie down Diplomatic Relations point.

  • Royal Marriage may arrange royal marriages with others. This will improve relations by +25 while in effect. Only available to monarchies, Noble Republics and Dutch Republics.
  • Proclaim Guarantee will call the nation that guaranteed into the war if someone declares war on the guaranteed country. Grants the nation that guaranteed +10 relation points.
  • Offer Alliance proposes to form an alliance with the target nation. Grants +50 relations if accepted.

改变自己的观点

Although human-controlled countries do not have game-defined attitudes toward other nations (except their rivals, subjects and overlords), they still have numerical opinion values which enable or effect diplomatic options. For example,

  • In order to form an alliance opinion in both directions has to be positive.
  • Declaring war against a country viewed too positively hurts stability.

As of patch 1.13 improving relations goes both ways however the improver only gets the bonus at half speed to a cap of +50. For example, if Austria was to improve relations completely with France. France would like Austria +100 and Austria would like France +50.

One way to raise one's own country's opinion of another country is to ask for military access. Other opinion modifiers work both ways: a royal marriage, having the same dynasty, rival modifiers and religion modifiers affect both countries' opinions.
