Each country has an opinion of every other country that it knows 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 the other country, such as by entering agreements with it or joining coalitions against it. Relations are shaped by diplomatic actions, the countries' relative power, their proximity, their recent wars, their religions, the casus belli that they have against each other, and events. As such, how country A views country B is sometimes very different from how country B views country A.
Attitude[edit | edit source]
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.
While the descriptions below refer to the player, AI nations also have attitudes towards other AI nations.
- 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: 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: 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: 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.
- Ally: This nation views the player as an ally.
Available only with the The Cossacks DLC enabled.
- 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). However this attitude will not deter the AI ally from joining your offensive wars, unlike the threatened attitude, which will give −120 reasons to join your wars.
- 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: 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: This subject nation views the player positively, has low liberty desire, and will cooperate in times of war and be little inclined to declare independence.
- Disloyal: This subject nation views the player negatively or with hostility, has high liberty desire, will refuse to participate in wars, defend the player's land or pay taxes, and is more inclined to declare independence.
- Rebellious: This subject nation views the player as weak and unjust, and will be very likely to declare an independence war.
- Overlord: This country views the player as one of its subjects.
- Domineering: This nation feels like the player should be its subject nation and will pursue any attempt to make it that way. An allied nation that develops a domineering attitude toward the player will tend to break any alliances, as the domineering attitude gives -1000 reasons to stay in an alliance.
- 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: The nation doesn't know the player exists, or else the nation is human-controlled and thus unpredictable.
Attitude table[edit | edit source]
- Antagonize: The AI considers them a potential target for war
- Annex: The AI desires complete conquest of them
- Weaken: The AI want to weaken them by releasing countries, allying/guaranteeing their neighbours, etc.
- Coalition: The AI want to form a coalition against them (Applies for rivalry attitude if the rival has at least 50 Aggressive Expansion against the target nation)
- Warn: The AI want to send warnings
- Vassalize: The AI want to vassalize them
- Ally: The AI actively desires an alliance with them
- Befriend: The AI want to raise relations with them
- Protect: The AI want to protect them
- Threat: The AI want to protect themselves against them
- Ignore: The AI want to actively ignore them
Manually setting attitude[edit | edit source]
Available only with the The Cossacks DLC enabled.
- Main article: Diplomatic feedback#Managing attitude
Player nations have a default attitude towards other nations based on what the attitude of an AI nation would be. Players may manually adjust their attitude, however, to one of Friendly, Neutral, Hostile or Threatened.

Relation modifiers[edit | edit source]Please help with verifying or updating this section. It was last verified for version 1.25.
Aggressive expansion[edit | edit source]
Please help improve this article or section by expanding it with:
- AE caps for different peace terms(vassalizing seems to be capped at 100 dev and forcing union is capped at 250 dev. But it might be that peace terms modifier multiplied by the dev is capped at 50)
- how exactly is AE from no-cb and breaking truces impacted by the other modifiers(e.g. religion, culture, hre membership, distance)
- modifications if the aggressor is the defender in a war
- describe everything in a manner which can be understood easier
- impact of threaten war
- AE increase when target and loser are subjects of the same overlord
- Vassal actions: overlord gains full aggressive expansion penalty from all actions of its vassals
- AE for each province is calculated separately and then rounded down
- add more AE impact modifiers (ae_impact in the game files).
Aggressive expansion is a game mechanic modeling the negative diplomatic impact on other nations caused by aggressive behavior, mainly when expanding the country through annexing provinces and force vassalizing enemies. If a diplomatic relation suffers from aggressive expansion penalty, it will be listed in the detailed relationship view. When negotiating a peace, the additional amount of aggressive expansion that makes the sum go beyond -50 will be listed in the interface with the notification of countries that might join coalition against the player.
Causes[edit | edit source]
AE is generated by various peace terms, by breaking a truce, and by declaring a war without a casus belli. The amount of aggressive expansion that a target country gets towards an aggressor country for actions of the aggressor against a loser country depend on the religion, culture, distance and various other attributes of the target country compared to the provinces taken or towards the loser country or the aggressor.
The peace deal description in the game contains a base aggressive expansion which is independent of the target country and calculated as follows:
- development is the development of the conquered province (capped at 30) or the development of the target country (for peace terms which affect the whole country)
- CB modifier is 100% for Conquest, 75% for Imperialism, 25% for Reconquest
- Noncobelligerent modifier is 150% for non-co-belligerents and 100% otherwise
- Peace term modifier:
The base aggressive expansion is then modified based on the target country:
- Religion modifier is based on the state religion of the target country compared to the state religion of the loser. It is 50% if they are the same, 0% if they are different, but in the same religious group and -50% if they are in different religious groups
- Infidel conquest modifier is 50% if the target country has the same state religion as the loser country and the state religion of the aggressor country is in a different religious group
- Culture modifier is 50% if the primary culture of the target country is the same as the culture of the province, 25% for different culture in the same culture group, 0% for unrelated culture
- HRE modifier is 50% if the conquered province and the target country are part of the HRE
- distance is the ingame distance between the conquered province and the nearest province of the target country. This value is rounded down to the nearest multiple of 100 and capped at 400.
- Ally modifier is 2/3 if the target nation is allied to the aggressor and 1 otherwise
- Subject modifier is 10% if the target nation is a subject of the aggressor and 100% otherwise
Effects of Aggressive Expansion[edit | edit source]
- Opinion will be reduced by the aggressive expansion penalty. The negative penalty will decay by a base of +2 per year, further increased by bonuses to improve relations.
- Attitude towards the aggressor may change to outraged as the aggressive expansion penalty increases in strength. It is less likely for a nation with a high opinion of the aggressor to become outraged, but this is not foolproof if too much expansion is taken.
- Coalitions may be formed against an aggressor by nations with at least a −50 aggressive expansion relations modifier. There must be at least 4 nations who do not hold a truce with the aggressor, have at least a −50 aggressive expansion modifier, and have a negative opinion of the aggressor in order for a coalition to form. Coalitions are unlikely to form if the combined power of all potential members is much lower than that of the target country and its allies.
AE impact modifiers[edit | edit source]
The base formula for aggressive expansion impact above is also further modified by additional modifiers which are added to the formula afterwards. These modifiers include:
Additional modifiers include:
- 20% for having The Girondists faction in control as a Revolutionary Republic. Requires .

Border friction simulates the tensions felt by countries with neighboring provinces due to things like trade value, immigration, etc.
- Border friction events can occur between nations with this modifier. These events will occur more or less often depending on the opinion held between both nations.

Historical friends and rivals[edit | edit source]
Historical friends and historical rivals are pre-set by the scenario's starting conditions, and do not change over time (except by events). 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 occur when historical friends are fighting each other.
List of historical friends in 1444:
- Austria – Hungary
- Bosnia – Serbia
- Bremen – Hamburg
- Bremen – Lübeck
- Bremen – Riga
- Castile – Portugal
- Denmark – Norway
- Hamburg – Lübeck
- Hamburg – Riga
- Kochin – Vijayanagar
- Lithuania – Poland
- Livonian Order – Riga
- Livonian Order – Teutonic Order
- Lübeck – Riga
- Portugal – Spain
- Theodoro – Trebizond
- Venice – The Knights
List of historical rivals in 1444 as defined in countries' history files.
Improving relations[edit | edit source]
There are several diplomatic actions available if a country wants 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 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 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 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.
Changing own opinion[edit | edit source]
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 affect diplomatic options. For example,
- In order to form an alliance, opinion in both directions must be positive.
- Declaring war against a country viewed too positively hurts stability.
- In order to take the decision to Revoke Restraint of Appeals, the country must have +100 opinion of the Papal State.
If Castile was to improve relations completely with France. France would like Castile +100 and Castile 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.
