By the way, I know we have already had the discussion long ago, but the division of Catalonia in Old and New Catalonias is so many layers of wrong that it's bothering me a lot. It's both inaccurate, since such division wouldn't be used until the 1800's and by historians, and ineffective, since it removes the de jure claims the Counts of Barcelona should have to be competeing for Muslim lands with Aragon, who now has the upper hand in a royal way.
The thing is because you need two duchies to create a kingdom, you wouldn't be able to form the Kingdom of Catalonia with de jure Catalonia only.
