A claim on a province is an assertion that that province should be part of a nation, and can be gained in several ways. Claims exist in two versions: permanent and temporary.

Temporary claim[edit]

A temporary claim is a type of claim which can be acquired through the fabricate claims covert action, events and missions[1]. A temporary claim will disappear after Time Icon.png 25 years if the claimed province is not owned by the claimant country (note that the claim retains its original expiry date, thus disappearing immediately if it has expired and the claimant country no longer owns the province). If the claimant country is at war with the province owner at the original expiry date, the claim will not expire until the end of the war.

Beside generation of a conquest CB (towards the current owner of the province), claimed provinces also provide the following benefits when conquered:

  • Core-creation cost.png -10% Core-creation cost
  • Local autonomy.png -10% Local autonomy

Fabrication[edit]

A diplomat can be sent to fabricate a claim on a neighboring province or a province across a single sea zone as long as the claimant nation and the onwer of the target province are at peace with each other (claim fabrications started while at peace will proceed normally even if war ensues between the two countries). If the diplomat is discovered, nations in the area will get a base 2.5 aggressive expansion relations modifier[2] and the claim will require 4 times more days to be completed[3]; the agent can only be discovered once per fabricating claim.

The base time to fabricate a claim is Time Icon.png 1 year[4]. This time can be affected by:

The modifier “time to fabricate claims” was renamed with patch 1.16.

Permanent claim[edit]

An example of a permanent claim from an EUIV developer diary

A permanent claim is a special type of claim which can only be granted by nation formation decisions. A permanent claim will never expire, and can only be revoked through war or events.

Having a permanent claim on a province provides:

  • The Conquest casus belli towards the current owner of the province.
  • Reduces core cost and core creation time by 25%.[5]
  • Reduces local autonomy after conquest by -10% for non-overseas provinces (from 50% to 40%)

AE generation reduction[edit]

Having claims (either permanent or temporary) on a province can reduce the aggressive expansion generated by taking the province if the correct casus belli was used to declare the war.

Casus Belli AE Modifier
Annexation War x0.50
Government Form War x0.75
Conquest x1.00
War for the Emperor x0.50
