Catalonia is a nation in Iberia. It does not exist in any start date, but can be released by separatist rebels, as part of a war settlement or peacefully as a vassal. Their primary culture is Catalan (Iberian) and the nation has cores on all provinces with this culture (Roussillon (197), Girona (212), Barcelona (213), Urgell, (2987), València (220), Alicante (1750), Tarragona (2988) and The Baleares (333). In 1444, Aragon controls Catalonia's cores. It can take the decision to form Spain.

Form Spanish Nation Militarily
This section may contain outdated information that is inaccurate for the current version of the game. The last version it was verified as up to date for was 1.25.
Since Catalonia doesn't exist at any starting point of the game, the player must release Catalonia from Aragon and begin as their vassal. The country will begin at a disadvantage, as Aragon will have higher development in addition to a larger starting army and navy. The player will need to immediately seek support for their independence from any rivals of their overlord, preferably a powerful neighbour such as France or Castile. Ideally an independence war should be declared before Aragon has time to secure powerful allies or unite with Castile in the Iberian wedding.
Should Catalonia win its independence, it's worth bearing in mind that the Iberian wedding will not occur if Aragon does not directly border Castile, so taking provinces to separate the two could be advantageous. A foothold in Italy could also be useful, to allow for potential expansion into Naples or Sicily in future.
At this point, the strategy for Catalonia will be similar to that of Aragon. Securing allies that rival Castile and expanding further into the Iberian peninsula will allow the military formation of Spain, opening up opportunities for colonization and domination of the Mediterranean.
