'''Casus belli''' is a Latin term meaning ''case of war''. In [[Europa Universalis IV|the game]], a country with a casus belli (commonly known as just "CB") on another country is deemed to have a valid cause for war. When [[Declaration of War|declaring war]], the player is presented with a list of available CBs. They may pick a CB from the list or choose to declare war without a casus belli and accept the penalties of {{red|+30}} agressive expansion and {{red|-2}} {{icon|stability}} stability

'''Casus belli''' is a Latin term meaning ''case of war''. In [[Europa Universalis IV|the game]], a country with a casus belli (commonly abbreviated to "CB") on another country is deemed to have a valid cause for war. When [[Declaration of War|declaring war]], the player is presented with a list of available CBs. They may pick a CB from the list or choose to declare war without a casus belli and accept the penalties of {{red|+30}} aggressive expansion and {{red|−2}} {{icon|stability}} stability (halved with full [[Diplomatic ideas]]).
  
Each casus belli has a particular '''war goal''' associated with it, generally either controlling a particular province or winning a certain proportion of battles. Meeting the war goal will cause the war score of whichever side has achieved it to gradually rise (up to a max bonus of 25% at a rate of +0.4% per month). The casus belli also determines what peace terms may be demanded at no or reduced [[Diplomatic Power]] cost. Extracting additional concessions beyond those of the original CB ('''unjustified demands''') will cost {{icon|dip}} diplomatic power to be demanded.

The casus belli also determines what peace terms may be demanded at no or reduced {{icon|dip}} diplomatic power cost; additionally, some CBs disallow some peace terms entirely. Extracting additional concessions beyond those of the original CB ('''[[unjustified demands]]''') will cost {{icon|dip}} diplomatic power to be demanded.

Having a claim allows the selection of the targeted province as a wargoal. The covert [[Espionage#Fabricate claims|Fabricate Claims]] diplomatic assignment provides a claim on a single province. The amount of time to fabricate a claim depends on how much claims the country's fabricatede, increasing by 5 spy network points per claim. In addition, many missions, both generic and country-specific, provide 'temporary' claims. Many unification national [[decisions]] give claims on a large region. There are also some events, such as Border Friction, that provide claims.

Having a claim allows the selection of the targeted province as a wargoal. The covert [[Espionage#Fabricate claims|Fabricate Claims]] diplomatic action provides a claim on a single province (for details of which provinces can have claims fabricated on them, see [[Espionage#Covert_actions|Espionage § Covert actions]]). This is an immediate action that costs a certain number of points of spy network strength, starting at 20 and increasing by {{red|5}} spy network points per existing claim. In addition, many missions, events and unification national [[decisions]] give permanent or temporary claims, sometimes on a large region. There are also some events, such as Border Friction, that allow claims to be gained.
  
A claim will expire in 25 years after a nation gets the claim. A claim can't expire during a war with the country you have that claim on.
+
A temporary claim will expire in 25 years after a nation first gets the claim (permanent claims never expire). A claim can't expire during a war with the province's owner; permanent claims never expire, though they can still be given up in a peace deal. Regardless of CB used, claims provide {{icon|core creation cost}} {{green|−10%}} core creation cost, or {{green|−25%}} for a permanent claim.

Conquest is ordinarily the easiest CB to get by simply [[fabricate|fabricating]] a [[claim]], but also the least useful. Taking more than a few provinces with Conquest can quickly result in a large [[coalition]] being formed against the player due to [[Aggressive Expansion]] (AE).  It is still desirable to forge claims before fighting, in order to reduce coring cost and time.

* Holy War and Cleansing of Heresy work on any heathen or heretic, which also removes diplomatic point cost for taking any province, and are both unlocked by the last Religious idea.
* Overseas Expansion, from completing the Expansion idea group, gives greatly reduced AE when fighting Asian and African nations (but is only available if in the Western, Eastern or Ottoman [[tech group]]).

* If you have a special CB due to your government form or religion that allows you to take land, you'll usually be better off using it when possible, since it's tailored to your needs. Claims are still useful in these situations, but not strictly necessary. [[Japan|Daimyo]], [[Pagan denominations#Mayan|Maya]] reforming the religion, the Emperor of China, and steppe hordes all want to conquer land with less AE and maybe warscore cost, while [[Pagan denominations#Nahuatl|Nahuatl]] trying to reform the religion want cheaper vassalization. The revolution target wants to Spread the Revolution (in fact it can hardly do much more), while their monarchist neighbours want to Crush the Revolution.
* Note that a Casus Belli only reduces the cost of provinces that fulfill its criteria. For instance, a Colonialism conquest of <Province> (with that province as the War Goal) has 25% Aggressive Expansion and 50% warscore cost, but only for taking colonies. Provinces on the same continent as the target's capital or directly connected to the capital will incur full costs. When choosing such a CB, it will list the names of all the applying provinces, or show the number of these provinces if there are too many.

If the goal of the war is not to seize territory or force-vassalize, then the choice of CB is less important, since extorting money or releasing nations doesn't cause AE. Conquest is fine to use in such a situation. If the country happens to be a rival and releasing vassals or countries is not desired, the special Humiliate Rival CB is ideally suited for this purpose. The drawback is that allies can't be called in on a promise of land with a CB that can't be used to fulfil that promise, so you will need favours.

Casus belli is a Latin term meaning case of war. In the game, a country with a casus belli (commonly abbreviated to "CB") on another country is deemed to have a valid cause for war. When declaring war, the player is presented with a list of available CBs. They may pick a CB from the list or choose to declare war without a casus belli and accept the penalties of +30 aggressive expansion and −2 Icon stability.png stability (halved with full Diplomatic ideas).

Each casus belli has a particular war goal associated with it, generally either controlling a particular province or winning a certain proportion of battles. Meeting the war goal will cause the war score of whichever side has achieved it to gradually rise (up to a max bonus of 25% at a rate of +0.4% per month).

The casus belli also determines what peace terms may be demanded at no or reduced Diplomatic power.png diplomatic power cost; additionally, some CBs disallow some peace terms entirely. Extracting additional concessions beyond those of the original CB (unjustified demands) will cost Diplomatic power.png diplomatic power to be demanded.

List of casus belli[edit]

War goals[edit]

Each CB has an associated war goal. This describes what each side has to do to get ticking warscore, i.e. additional warscore over time from having accomplished the goal. Wargoals include:

  • Take province / Defend province: Control a specific province. This may be a province chosen on declaring the war, or the capital. Each side gets ticking warscore as long as they control the target. Neither side gets ticking warscore if a third party (e.g. rebels) controls it.
  • Show superiority: Have at least 10% warscore from battles. No side gets ticking warscore if neither has said warscore from battles
  • Blockade ports: Amount and rate of ticking warscore scales by the proportion of blockading.

Triggered[edit]

A triggered casus belli appears when certain actions are performed (like insulting other countries), and can also be given by events and missions. Triggered casus belli only last for a certain amount of time before they expire and are no longer valid. Without Art of War.png Art of War, none of these CBs can be used by an overlord on a subject's behalf.

Conquest details[edit]

Having a claim allows the selection of the targeted province as a wargoal. The covert Fabricate Claims diplomatic action provides a claim on a single province (for details of which provinces can have claims fabricated on them, see Espionage § Covert actions). This is an immediate action that costs a certain number of points of spy network strength, starting at 20 and increasing by 5 spy network points per existing claim. In addition, many missions, events and unification national decisions give permanent or temporary claims, sometimes on a large region. There are also some events, such as Border Friction, that allow claims to be gained.

A temporary claim will expire in 25 years after a nation first gets the claim (permanent claims never expire). A claim can't expire during a war with the province's owner; permanent claims never expire, though they can still be given up in a peace deal. Regardless of CB used, claims provide Core-creation cost.png −10% core creation cost, or −25% for a permanent claim.

Choosing a CB[edit]

Conquest is ordinarily the easiest CB to get by simply fabricating a claim, but also the least useful. Taking too many provinces can quickly result in a large coalition being formed against the country due to aggressive expansion (AE). It is still desirable to fabricate claims before fighting, in order to reduce coring cost and time, and the diplomatic point cost.

  • Holy War and Cleansing of Heresy work on any heathen or heretic, which also removes diplomatic point cost for taking any province, and are both unlocked by the last Religious idea.
  • If you have a special CB due to your government form or religion that allows you to take land, you'll usually be better off using it when possible, since it's tailored to your needs. Claims are still useful in these situations, but not strictly necessary. Daimyo, Maya reforming the religion, the Emperor of China, and steppe hordes all want to conquer land with less AE and maybe warscore cost, while Nahuatl trying to reform the religion want cheaper vassalization. The revolution target wants to Spread the Revolution (in fact it can hardly do much more), while their monarchist neighbours want to Crush the Revolution.
    • Becoming revolutionary is a common world conquest strategy, because the bonuses of being the revolution target and the reduced warscore and diplomatic power cost of the revolutionary CB, in combination with Administrative efficiency.png administrative efficiency from high absolutism, make it possible to conquer huge amounts of land very quickly.
  • Note that a casus belli only reduces the cost of provinces that fulfill its criteria. For instance, Colonialism has 25% aggressive expansion and 50% warscore cost, but only for taking provinces that are overseas for both or from overseas colonial nations. Provinces on the same continent as the target's capital or directly connected to the capital will incur full costs (unless they're a colonial nation). When choosing such a CB, it will list the names of all the applying provinces, or show the number of these provinces if there are too many.
  • Also note that the reduced warscore cost also affects options that are set on total province cost. So if a country's warscore cost is just over 100, the reduced cost for being wargoal might just make the country annexable/vassalizable.

If the goal of the war is not to seize territory or force-vassalize, then the choice of CB is less important, since extorting money or releasing nations doesn't cause AE. Conquest is fine to use in such a situation. If the country happens to be a rival and releasing vassals or countries is not desired, the special Humiliate Rival CB is ideally suited for this purpose. The drawback is that allies can't be called in on a promise of land with a CB that can't be used to fulfil that promise, so you will need favours.
