Main article: Aragonese events

Aragon's events focus on various significant events in their history.


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.

  • If Spain is a duchy, change its government rank to kingdom.


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.

(Note: The Iberian wedding event cannot happen to Aragon if it is controlled by a human player.)

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.

  • 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.

Strategy #3[edit]

Main strength of Aragon is its unique position with heavy presence in Genoa trade node. You can expand in all possible directions, and these directions depend just on player preferences. While both Portugal, Castile and France are better at colonizing than you are, you can simply sit at home and take benefit of trade directed almost from all over the world. No need to invest in Exploration, since your Iberian neighbors will colonize New World for you. No need to spend tons of money on colonial maintenance. Just control few important provinces with trade centers and estuaries, get Eastern trade directed around Africa or through Alexandria, cripple Castile and Portugal so they are no threat to you and always keep France at your side.

  • Beside your original provinces in the home trade node, Provence, Genoa and Firenze must be acquired. Lyonais would be nice but good relations with France are preferable. Northern Italy is generally out of the Emperors protective umbrella by 1490, and it's good time to pick what you need without making too many enemies.
  • Take Southern Iberia from Castile and Granada, and both Lisboa, Porto and Tangires from Portugal. Few extra province taken from Castile will ensure they never again pose any significant threat to you. If you want to form Spain, do it, but living and colonizing Castile is just too good a money cow to slaughter, so leave several provinces for them to direct trade to you. Portugal is actually quite good as an early ally, but, unfortunately, they got historical friendship with Castile, and will most likely fight against you on their side if precautions aren't taken.
  • While low on manpower, mercs are cheap for you. Both Innovative and Administrative make them even more attractive. Since you probably won't aim at controlling all Mediterranean coasts, province coring won't be as crucial, and Innovative provide many extra benefits.
  • Navy is everything to you. Maritime, Quantity and Naval are probably the best to ensure your enemy will need to go huge distances and waste diplomatic power getting military access just to reach you. Blockade straits and ports and your opponents will be far less likely to get any significant advances on you in wars. This will do wonders with Turks, your most likely nemesis in mid game.
  • Trade is great. Just get it latest as number four idea group.
  • Expansion might be an interesting choice if you plan to direct Asian trade around Africa. Otherwise Economic is much better for tall growth. CBs can be gained by spamming lucrative trade nodes with light ships and getting foothold there in trade conflicts. Again, aim at estuaries and trade centers, and create trade companies if Wealth of Nations is enabled.

How you use all this wealth from trade is up to you ;-)
