The Europa Universalis IV Converter is a DLC for Crusader Kings II. It turns a saved game of CK2 into a mod for Europa Universalis IV. The DLC was originally available as a pre-order bonus for EU4; shortly after that game's launch it was made available separately as DLC, priced at €/$9.99.

On GNU/Linux the savegames are exported to ~/.paradoxinteractive/Crusader\ Kings\ II/eu4_export/mod/.


Start date[edit]

  • A CK2 save (from any year) is turned into a mod for the EU4 start-date of 1444, allowing the player to continue on to 1821.

Nations and national ideas[edit]



  • With Minimal Crown Authority (Autonomous Vassals), kingdom-level vassals and duke-level vassals will become vassal states rather than integrated into the whole realm.
  • With Conclave enabled, this is tied to a realm's council power. With council power abolished, the whole nation will stay independent. If any council laws are active, there will be some vassals. The centralization law doesn't affect this.
  • A maximum of 4 EU personal unions are created from a nation's largest vassals. The rest will stay part of the nation.
  • Muslim nations get vassals instead of personal unions to somewhat represent that they use an Iqta system rather feudalism.

The Holy Roman Empire[edit]

  • The Holy Roman Empire is implemented using EU4's HRE mechanics. All vassals remain unless crown authority is Absolute.
  • The seven largest vassals within the empire will become electors and the rest of the direct vassals will become normal princes.
  • If crown authority is absolute the HRE becomes a single nation instead. With Conclave DLC, the HRE becomes a single nation when the council is not enabled.


  • Technology is determined by a realm's total tech level compared to the average tech of all realms. Those with high tech levels will be in the western tech group. In the case of Sunset Invasion, the Aztec and Inca will also receive High American as their tech level.
