Secure the High Kingdom of the North Sea: What does "England must be departitioned" mean?

I am playing Crusader King 3 with the Northern Lord flavor pack. There is a decision to "Secure the High Kindom of the North Sea".

One requirement reads:

  • The Danelaw currently has De Jure Counties, and England must be departitioned first

I am currently King of Norway, Denmark, and England as well, trying to hold it for 30 years. Now I realize I also have to fullfill that requirement and I have no clue what it entails.

What does departitioning England mean? (The Danelaw already exists. I am fighting with them for the North Sea Heartlands as well.)


The requirement means:

  • England must have had a de jure partition split, meaning the Danelaw and England coexist
  • afterwards you still have to usurp the remaining Danelaw. (I conquered England when the Danelaw existed already. I don't know if it could work with conquering England as an Danelaw King)

Once I conquered all of the remaining Danelaw territory, an event appeared proclaiming that the Danelaw title was destroyed and all Danelaw claimants lose their claim, only England remains.

Event upon destruction of the Danelaw ending the partition with England

Decision for the creation of The North Sea Empire
