I am currently in the process of editing the monarch files for the various states of Europe, from information I have from an unrelated project. The editing mainly consists of adding the exact date of the change of power from one monarch to another, although there have been a few other minor adjustments such as changing names to the native language and the adding of well-known nicknames or titles. As of this moment, I have modified Baden, Bavaria, and Spain (the last as a result of the Aragon project I recently posted - don't worry, Ferdinand is still in the Spanish list
), but I should have others finished soon as well. I will gladly put these at the disposal the IGC team, or anyone else who would want them for that matter.
