Shield Aragon.png
The Crown of Aragon emerged as a major power from humble origins as a mere County in the Pyrenees. After winning its independence from the now much reduced Kingdom of Flag of Navarra Navarra, Aragon entered into a union with the County of Flag of Catalonia Barcelona. Its monarchs were eager participants in the Reconquista, the campaign of conquest against the Muslim states of Iberia, which saw Aragon expand to its current southerly extent and add the Kingdom of Flag of Valencia Valencia to the composite Crown.

The fates of Aragon and Navarra are once again tied together; the King of Navarra is also the heir to the Aragonese throne. Should King Joan manage to survive his father Alfons V while preserving the independence of Navarra, the two nations will be joined in a personal union under one monarch.

On the subject of dynastic unions, the Kingdom of Flag of Naples Naples in southern Italy is also subject to the Crown of Aragon. Aragon rules Flag of Sicily Sicily directly, but Naples has yet to be fully integrated into the Crown following King Afonso’s conquest of the kingdom in 1442. The former King of Naples, René of Anjou, has fled to Flag of Provence Provence where he continues to insist upon his claim not only on Naples but also on Aragon itself as well as Flag of Jerusalem Jerusalem.

Aragon’s relationship with its powerful neighbour Flag of Castile Castile is difficult to pin down. Though these nations share a dynasty, the feuding House of Trastámara is rarely at peace with itself. At times it seems as though peace may be possible and that the two Crowns could be united into one, while at other times it seems that the kingdoms are destined to struggle against one another for eternity as bitter rivals.

Beyond dynastic matters, Aragon is a nation deeply concerned with dominating trade in the Mediterranean. Aragon’s Consulate of the Sea aims to regulate and administrate all trade in the region, while Catalan and Valencian merchants struggle against merchants from Flag of Genoa Genoa and Flag of Tuscany Tuscany to control the flow of profit. Aragon also has designs upon the elusive silk trade. Silk has traditionally seen almost no production in Europe; its secrets are closely guarded but now seem to be within reach.

Aragon is a Catholic country that lies along the Iberian shore of the Mediterranean Sea, possessing the islands of the western Mediterranean. They border Flag of Castile Castile, Flag of Navarra Navarra and Flag of France France and have a personal union over Flag of Naples Naples. They, along with Castile, Flag of Portugal Portugal, and Flag of Navarra Navarra, can form Flag of Spain Spain. Their primary culture is Aragonese (Iberian). Historically, they united with Castile through marriage.

Missions[edit | edit source]

Main article: Aragonese missions

Aragon's missions mostly center around holding onto their Mediterranean possessions, gaining new ones, and uniting Iberia.

Events[edit | edit source]

Main article: Aragonese events

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

Iberian wedding[edit | edit source]

The Aragonese version of the Iberian Wedding event can only happen if Aragon is controlled by a human player and Castile is controlled by the AI. In the event that Aragon is not human controlled, the slightly different original Iberian Wedding event may fire instead.

Between 1450 and 1530, if neither Flag of Castile Castile nor Aragon are vassals and the monarch of one of them is male and the monarch of the other is female, then there is a high chance of this event happening. The event can also happen if Castile has a regency regardless of the gender of Aragon's ruler. After it fires, Flag of Castile Castile can enter into a personal union led by Aragon with a -50% Liberty desire.png liberty desire reduction if you choose to take the union with Flag of Castile Castile. You can also choose to refuse the personal union, and instead take a better heir. Usually it is recommended to take the union, as it will allow you to circumvent the Aggressive Expansion, and what it will take to core the provinces from Castile if you want to end up forming Flag of Spain Spain. Also, its just a bunch of free land, plus a way to further move down your mission tree.

Aragon-Navarra succession[edit | edit source]

“Joan II de Trastámara” is Flag of Navarra Navarra's starting ruler and Flag of Aragon Aragon's starting heir. If he dies in one country, he also dies in the other one. If he ascends to the throne of Aragon, the event The Death of King Alfonso will happen if its conditions are fulfilled which can lead to a personal union between the two countries.

Strategy[edit | edit source]

Strategy The below is one of many player suggested strategies for Aragon. Bear in mind, due to the dynamic nature of the game, it may unfold differently for other players.

Flag of Aragon Aragon is an interesting yet uncommon choice, as Flag of Castile Castile and Flag of Portugal Portugal are usually heavily favoured. Castile is Aragon's main rival, and Spanish ambitions have them working to absorb Flag of Aragon Aragon into a common Spanish state. Both Flag of France France to the north and the Berber states to the south are waiting to strike. France is quite difficult to defeat while the Berber countries act as a large nuisance should the player focus on affairs in the Iberian Peninsula. Flag of Castile Castile cannot form a Personal Union over Aragon via the Iberian wedding if Aragon is controlled by a human player. Instead, Aragon may have its own version of The Iberian Wedding fire, making Flag of Castile Castile a junior partner in a Personal Union under Aragon, essentially reversing the original event to be in Aragon's favor.

Opening moves and Ideas for beginners[edit | edit source]

Flag of Portugal Portugal may attack if Flag of Castile Castile decides to take advantage of Aragon's situation. Also, they are much less likely to declare war on Aragon and have one of their own allies join. Therefore, an alliance with Flag of France France is desirable for any player playing Flag of Aragon Aragon, as it allows the player to defend or expand into Iberia with relative ease due to the strength of the French military. The alliance will also prevent Flag of France France from expanding into Aragon's lands making Aragon's situation much more hopeful. In addition to these benefits, Aragon can call France into an offensive war fairly often due to the favors mechanic, so long as the player is willing to aid Flag of France France in their offensive campaigns.

Alternatively, if Flag of Castile Castile starts friendly with Flag of Aragon Aragon, the player could safely declare war on Flag of France France after subjugating Flag of Navarra Navarra. Flag of Aragon Aragon has a very defensible position on the Pyrenees Mountains. High attrition to the French in the winter and low supply limit will weigh battles toward the defender's favour. When France is in a crippling war, the player may decide to declare war. It would be beneficial to ally Flag of England England, Flag of Portugal Portugal, and/or France's rivals. England almost always rivals on France in the 1444 start date, so Aragon can promise them land, deliver, and keep the rest for the Aragonese Empire. An opportunity may arise during the Surrender of Maine, depending on whether Flag of England England decides to give back Maine or not.

Naples: Flag of Naples Naples, after the Emperor update, has changed a bit. After Alfonso V dies, an event will fire which will give you the option of releasing Naples, or keeping with 50% liberty Desire. It is possible to keep them, but you will need to heavily manage their liberty desire, at least until the modifier dies down, though only at around 0.5% a year. Of course, you may release them and try to pursue their lands in the future.

Expansion[edit | edit source]

The player has many avenues for expansion. The most challenging, yet the most fruitful, is expanding in the Iberian Peninsula. The weakest country of which is Navarra: a one province minor located in northern Iberia. Aragon's unique mission to subjugate Navarra allows a declaration of war before they get any major allies; Aragon also has event, which allows Aragon get a personal union over Navarra peacefully. After Flag of Navarra Navarra and Flag of France France are dealt with, the player may expand into Castile. This would allow Aragon to grow quite large in size and to become the dominant Iberian power. In general, it is advised to attack Flag of Castile Castile while they are in the Castilian civil war, allowing Aragon to conquer Iberia with minimal resistence from a now-disorganised Castille. However, since the chance of Iberian Wedding is quite high, there may be no need to fight Flag of Castile Castile.

In addition to conquest in Iberia, the player may choose to colonize. Once they have reached a certain technological level, they will have the opportunity to expand into the New World or the African continent. In both places, the player will have vast opportunities for wealth and prestige. With the new native policy mechanics, it is easier to maintain colonies without garrisoning large forces in these settlements. When low on manpower, mercenaries are a good choice for Aragon. Aragon's first national idea is -15% mercenary maintenance.

With the Golden Century.png Golden Century DLC enabled, the Aragonese mission tree allows the player to obtain a myriad of permanent claims when you finish each mission. With control of Sicily and Sardinia, the player also has the advantage of taking all locations in the Mediterranean. This allows Aragon to expand into Italy with the help of Naples or into North Africa with the support of Portugal or another friendly power. Flag of Portugal Portugal could be subjugated under a personal union by the mission just like Flag of Castile Castile, so Flag of Aragon Aragon's colonization may not be as essential as in the previous patch.

Trade[edit | edit source]

Flag of Aragon Aragon has an advantage in that they are located in their own trade node of which they own all the provinces, with the exception of two owned by Flag of France France. Their Italian provinces provide incentive to keep expanding into the Genoa trade node. The player may decide to focus on trade instead of colonisation, as the major powers' trade might just flow straight to Aragon, with the help of merchants. With this strategy, the exploration and expansion idea groups may not be obtained in exchange for the trade and/or economic ideas. It would be beneficial to annex provinces with desirable trade goods and trade power to dominate the Genoa trade node. Once Genoa trade node is fully controlled, the player may also seek the other Mediterranean end node, Venice trade node.

It is recommended to cut down the colonial powers' size, but not completely destroy them so that those countries can still colonise. One possible way is allowing your junior partner Flag of Castile Castile and Flag of Portugal Portugal to colonize for you.

Mid-to-late game[edit | edit source]

As Flag of Aragon Aragon's path is quite different from Flag of Castile Castile, the player can choose Aragon's own destiny and recognise the nation's Mediterranean ambitions. Flag of Aragon Aragon also has an achievement called Consulate of the Sea. Should Aragon move further into Europe, the player may contend with the complex politics. The Aragonese trade empire should be involved with the Crimea and the Alexandria trade nodes. The player should try to plan ahead with Aragon's idea groups. Berbers, Italians and the Ottomans are your main enemies; Flag of Russia Russia,Flag of Austria Austria, and Flag of England England are advantageous late-game allies.

If Aragon conquers the parts of the Iberia Peninsula needed for Flag of Spain Spain and forms Spain, colonization is recommended.

Ideas[edit | edit source]

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

  • Economic ideas is a powerful idea group allowing the player to build a strong economy in preparation of the future.
  • Exploration ideas is a very strong idea group allowing the player to colonize the new world and become a colonial power.
  • Trade ideas are very powerful if the player desires to create a trade empire.
  • Innovative may be desired for a further mercenary cost reduction and cheaper technology.
  • If Aragon decides to create a vast mercenary army, Administrative ideas would be a very good choice for its mercenary benefits. If the player is very aggressive, the core-creation cost reduction will also be beneficial.

Optimal Start for More Experienced Players[edit | edit source]

Opening Moves: There are a few things to do before unpausing the game. The player should ally Flag of Austria Austria, Flag of Castile Castile, and one or more strong rivals of the Flag of Ottomans Ottomans. Additionally, rival Flag of Morocco Morocco, the Ottomans, and Flag of France France, as you will be expanding into them in the near future. Optionally, one can disinherit the current heir, but this can be risky as it does pose the risk for a worse heir, and the hit to Yearly prestige.png -50 is significant. Estate privileges don't matter all that much, so apply whichever privileges are most preferred to the player. Next, the player should build up to army and naval force limits, and it may even be recommended to hire the Free Company or another small mercenary stack. Once prepared, ideally on the 11th of December, declare a no-CB war on Flag of Byzantium Byzantium. Usually, Byzantium will ally either Flag of Serbia Serbia, Flag of Theodoro Theodoro, or another small orthodox nation. In this war, the goal is to vassalize Byzantium and obtain ducats and/or war reparations from their allies. It is recommended to vassalize Byzantium because the player can use their cores to further weaken the Ottomans and increase their own holdings. After this war, there are a couple options for expansion and a few have been listed below. Sometime during or after this war, depending on RNG, your ruler will die and an event will fire which gives Aragon a personal union with Flag of Navarra Navarra. This event will also lead to another event allowing the release of Flag of Naples Naples as an independent country or the retaining of the personal union. It is important that the player doesn't give up the union with Naples, and begins to manage the added +50 liberty desire. This can be done through supporting loyalists and improving relations with Naples.

Expansion Routes : 1: Flag of Provence Provence. They start off the game allied to Flag of France France, so the player has to be very opportunistic. If they become vulnerable at any point, don't hesitate to declare an offensive war, especially if they are excommunicated or if their ally France won't join. This gives Aragon permanent claims in Southern France, and can eventually lead to claims on all of France.

2: Balkans: At this point, the player should have Flag of Byzantium Byzantium as their vassal. This means you have a reconquest Casus Belli on Flag of Athens Athens, Flag of Ottomans Ottomans, and Flag of Epirus Epirus and can attack them to grow Byzantium. However, the mighty Ottoman Empire will be a difficult target for Aragon alone but with the assistance of strong allies a war is winnable.

3. North Africa: Aragon gets claims through missions on nations like Flag of Tunis Tunis, Flag of Morocco Morocco, and the Berber nations in general. Expansion into these areas should be straight forward in this manner. For added ease, the player could take Religious idea group.png Religious ideas to access the Deus Vult CB to take trade from the Tunis, Safi, and even Alexandria trade nodes. While the benefits of invading North Africa may seem small, they are essential if you want to form Flag of Roman Empire Roman Empire, get the Consulate of the Sea achievement, or get the Mare Nostrum achievement.
