De jure kingdoms of Britannia

Each one's de jure counties (common/landed_titles), biggest first, on the game's paper map.

How to use these IDs in the console
  1. In Steam, add -debug_mode to the game's launch options (Properties → General).
  2. In the game, open the console with the ` key (§, ~ or ^ on some keyboards).
  3. Paste the command (give_title e_britannia) and press Enter. Using the console turns achievements off for that game.
