National decisions[edit]

Execute decision.pngForm Spanish Nation Militarily

Global expansion in newly discovered areas and the establishment of colonies is transforming Spain into one of the most powerful and wealthiest nations of our time. Spanish explorers are constantly moving into new territories and extending our borders. Immense amounts of gold and silver are being brought back to our motherland, filling the coffers of our state Treasury.

Potential Requirements Allow

  • changes to Spain.
  • If this country owns Madrid, Madrid becomes the capital.
  • gets a claim on all not owned provinces of the Spanish region.
  • gets the modifier "Increased Centralization" for 20 years:
    • Autonomy.png -0.05 Monthly autonomy change
    • National unrest.png +1 National unrest
  • Prestige.png +25 Prestige


Aragon is an interesting choice, and an uncommon one as the Iberian choices of Castile Castile and Portugal Portugal are usually heavily favored. Castile is Aragon's main threat, Spanish ambitions have them working to absorb Aragon into a common Spanish state. France France is warmongering to the north and the Berber countries are waiting to strike in the south. France is very hard to defeat while the Berber countries are very big nuisance as the player deals with affairs in the Iberian Peninsula.

French alliance[edit]

An alliance with France France is useful for two reasons. Firstly, it gets rid of the secondary threat of France expanding her southern border. The alliance also does not bring much risk to Aragon, as Aragon is hidden behind France from European threats (and France will drag Aragon into wars). As for Castile Castile, Aragon's primary concern, France is a powerful ally that can keep Castile at bay. An alliance with Portugal Portugal may not be a bad idea, especially if Aragon intends to expand into Castile, but most times, an ally who isn't involved in Iberian politics is a good idea.


The Mediterranean islands are useful for developing a strong navy and trade presence. Sardinia Sardinia and Sicily Sicily are good choices. Navarra Navarra is an easy choice on land, and should be taken before Castile Castile or France France get to it. After developing this far, the player will notice a lack of good missions, and Aragon will only be a middle-level European power. The next options depend greatly on Aragon's unique situation.

  • Capture North African cities! At least those that give the trigger "Barbary Pirates" for Iberian cultures. This will propel Aragon farther into a powerful naval force. This also allows for an African campaign if Aragon wants to wage crusades into Muslim territory.
  • If Aragon can find Castile Castile in a weak spot, try to exploit it. Diplomacy may be a good idea for Aragon if Wealth of Nations is not installed. If Aragon wants a strong personal union, try to royal marry whoever Aragon wants to change their dynasty.
  • Portugal Portugal will like you if they are not getting along with Castile Castile.
  • Italian ambitions, or other islands. Do not be afraid to exploit a weak Naples Naples or Venice Venice. Crete Crete, Malta, Sicily Sicily and other Italian/Mediterranean states offer excellent opportunities to expand trade and naval power. Ensure France France stays on Aragon's side when entering Central European politics.

Mid/late game[edit]

As Aragon's path is not well defined, the player can choose Aragon's own destiny. If Aragon conquers the parts of the Iberia Peninsula needed for Spain Spain and forms Spain, get ready to colonize. If Aragon gets in Europe have fun with the complex politics. A trading titan will want to be involved with Crimea and the Alexandria trade node. Try to plan ahead with Aragon's idea groups.

Strategy #2[edit]

Early game[edit]

Take the mission to vassalize Navarra Navarra immediately and use the casus belli to get Navarra as their vassal. This prevents Castile Castile from getting Navarra. Remember to culture convert unaccepted cultures. After finishing these missions, attack France France if it is still in the Hundred Year War. If not, wait for a good time to strike such as when Castile and Austria Austria are at war with France. Get Austria as an ally and try to get Portugal Portugal as an ally. This is will scare away Castile and prevent them from attacking you. By this time, culture conversion of unaccepted cultures in Aragon's provinces should be finished, Navarra should be annexed, an army up to the force limit should be built, and a French province should have a claim fabricated upon. Declare war with France and use the fabricated claim as the casus belli. Defend in the Pyrenees if France sends its army to attack (which they should not if they are involved in a war with another power) . Once their army is crushed, siege out their southern provinces but keep a hunter-killer army to kill small groups of French units. Work your way up France and in the peace deal, take three or four provinces. Repeat this until France is very weak (do not forget to culture convert any captured provinces). Relations with Austria should be maxed out.

Note: It is no longer possible to culture convert French provinces until France no longer exists. It is preferable to get them as an accepted culture by taking enough of them to do so, and/or taking Humanist ideas early enough (2nd or 3rd Idea set).

Mid-game/ late-game[edit]

Aragon should now be so strong that Castile Castile is far weaker. With this shifted power balance, Austria Austria will like the player much more than Castile, which the AI usually allies with. This means war can be declared on Castile and Austria will join your side. This time, be a warmonger and take as many provinces from Castile as possible. Try to get Castile to annul treaties with Austria and release Galicia Galicia and Granada Granada. Do this one more time and don't culture convert, they're in your culture group. Now, hopefully you have the provinces to make Spain Spain, if not go to war with Castile a few more times. Now form Spain once all the required provinces are captured. Now you use the strategy which Spain would use which is to win the colonialism race. Do not forget to integrate Naples Naples.


Aragon should be a major naval and colonial power, yet they should not forget their military or economy.

  • Economic ideas should be the first idea to support your economy and ready the nation for colonialism. It also adds a nice boost to the player's income which is vital in war.
  • Exploration ideas should be the second idea group. Colonize an African province and aim for North America. The competition in North America is not as fierce as in South America. Try to block any other power from gaining a foothold in North America. Colonize Asia after getting the coastal provinces of North America. Then colonize the interior of North America.
  • Expansion ideas are great for the added boost to trade, colonialism, and ability to diplo-vassalize nations.
  • Take either Naval or Quality ideas. The Quality ideas might be preferred since they help both army and navy.
