This guide provides an optimal starting strategy to overcome initial financial deficits and build a strong economic and military foundation, helping you achieve any goal. From moving the capital to granting privileges, diplomacy, warfare, and economic development after the Black Death, we'll explore the key steps to a successful Castilian campaign.
EU5 Castile Beginner's Guide: Strategy for Building the Strongest Economic and Military Foundation
1. 👑 Castile Early Setup: Capital Relocation and Government Strengthening
· Castile starts with an initial financial deficit, but strategic setup can quickly turn it into a surplus.
· It is crucial to move the capital to Seville. Seville offers several advantages, including a high population, a good port, and control over the Guadalquivir River.
· Grant the following privileges to balance satisfaction.

· Set rivals to Navarra and Granada.
· Use the cabinet to increase control over the new capital and strengthen the government.
· Focus technological development on diplomatic capacity and institutional growth. If not close to Italy, you might choose 'Food Purchase Cost'.
· Delete all fortresses except those in Burgos and Santander near Navarra to significantly increase income.

2. ⚔️ Early Diplomacy and War Strategy: Conquering Navarra and Granada
· Begin espionage in Granada and Navarra, and improve relations with France.
· Ally with Aragon to create a stable environment for beginners. There's no need to rush the formation of Spain (no Imperial rank granted, unique development H4).
· Manage low-control regions by releasing 'Guitia' as a historical vassal.
· After achieving a spy network of 20 in Navarra and Granada, create a 'Conquest' casus belli.
· In the first parliament, change the administrative system from 'Adanto System' to 'Amalgamation Division', and 'Feudal Nobility' to 'Autocracy'.
· Achieving 100 legitimacy will result in a surplus. The cabinet should focus on 'Diplomatic Efforts' for the alliance with France, then revert to 'Government Strengthening' after the alliance.
· Plan to build a road from Seville to Valladolid and construct a Provincial Governor in Valladolid.
· During the Navarra war, check for Aragon's intervention. If Aragon defends Navarra, use Aragon's help to declare war on Granada first, inducing a two-front war.
· A two-front war can be easily won by blockading the straits with naval recruitment to prevent Moroccan landings, and subduing Navarra with northern forces and Granada with southern forces.
· Beginners should avoid invading the Maghreb. The enemy is strong, and there's a risk of malaria.

3. 🗺️ Renaissance Era Territorial Management and Vassal Control
· In the Renaissance era, always choose 'Administrative Focus' to leverage provincial infrastructure and proximity speed advantages.
· Navarra should be fully annexed, not made a vassal or march.
· There are two ways to handle Granada.
OptionDetails
When invading MaghrebOccupy 4 regions from Morocco and a Maghreb region (capital or mountain fortress region)
For easier gameplayFully annex Granada, then occupy specific regions from Morocco

· Newly acquired territories are managed as follows.
RegionHandling MethodNotes
NavarraRelease as a historical vassal (vassal state)Prevent economic losses in low-control regions like Bilbao
Almería, Granada, MálagaRelease as a March
CadizRetain directly and integrate through the cabinetMany cores and easy to secure control

· Ceding the Cadiz region to Málaga is also an option.

4. 💰 Economic Development and Black Death Preparedness Strategy
· Key priorities are 'Proximity Speed' development in the Renaissance era and constructing a 'Provincial Governor' in Valladolid.
· If funds for the Governor are insufficient, import gold from the market. Disable market automation and manually import gold, then cancel gold imports once the Governor construction is complete.
· Since Navarra serves a defensive role, other fortresses can be deleted.
· After allying with France, stop improving diplomatic reputation and refocus on government strengthening.
· In preparation for the Black Death, build hospitals in Seville, Cordoba, and Valladolid.
· Economic investment should focus on increasing RGO (Raw Goods Output) levels in regions with over 60% control.
Good RGOsCaution
Wood, Copper, Silver, Gold, IronDuring population decline due to the Black Death, maximum RGO levels may decrease and labor shortages may worsen, so invest carefully.

· Safer investments include constructing profitable buildings like markets and tailor guilds, building roads, and investing in capital buildings such as garrisons, royal courts, and royal guards.
· A general rule is not to invest in regions with less than 60% control.

5. 🌍 Expansion Goals and Government Reforms: Naval Governor and Portuguese Personal Union
· Once the economic foundation is stable, consider the following expansion goals.
Expansion GoalsFeatures
MaghrebClose to mainland and easy to secure control
RomeReduce the Pope to a single province in Rome and vassalize for infinite funds (current exploit)
NaplesHigh population, good RGOs, natural harbor
ConstantinopleHigh population, excellent RGOs, even better natural harbor (requires Ottoman/Bulgarian/Serbian military access, long fortress sieges)

· Construct a Naval Governor in Naples or Constantinople to increase control and income.
· To integrate vassals, force religion on the Andalusian vassal, then force culture. This will temporarily lead to disloyalty but will eventually recover.
· After achieving 50 naval power, change 'Autocracy' to 'Port Administration' in government reforms to construct a Naval Governor (e.g., Genoa).
· For the second development, choose 'Official City Rights' and build towns and cities in profitable locations. For example, in places like Carmona with poor clay RGOs, you can forgo RGO income and increase building income.
· If a claim to the Portuguese throne arises (a good claim to make your heir king), declare war and win with France's help. Upon the king's death, a personal union with Portugal will form. At this point, you should start improving relations with Portugal.

6. 📈 Prosperity After the Black Death and Castile's Future
· Despite a 50% population decrease due to the Black Death, you can achieve remarkable economic growth, turning a monthly 40 ducat deficit into nearly a 100 ducat surplus in just 20 years.
· With this strong foundation, you can pursue various goals in your Castilian campaign.
Future GoalsDetails
Personal UnionsAttempt personal unions with Naples, France, England, etc.
Territorial ExpansionIncrease income by conquering Maghreb
Conquer Alexandria, establish a Naval Governor, and secure immense income from the Nile Delta
ColonizationBegin overseas exploration and colonization of the Americas

· The early setup presented in this guide will provide a solid foundation to achieve any goal.
