Conquest of The New World – Siglo de Oro Steam Achievement Guide

Conquest of the New World – Spain Strategy (Deity)

Initially I thought Siglo de Oro was a “Seal of Gold”. I was wrong: It translates to “Golden Age”, “Golden Century”. A Golden Age it was indeed: The Spanish colonization of the Americas was by far the most extensive and impressive and given its head start (Columbus sailing west) it was also the longest: The Spanish colonial empire, starting 1492, lasted until 1975. Quickly after Columbus made landfall in the West Indies, the Spanish had conquered the Incan empire in the south and the Aztec and Mayan realms in Central America. All this is even more impressive since the Spanish had just reclaimed their homeland from Moorish rule in the very same year 1492. Read more about the Reconquista in the Into the Renaissance Spain Strategy (Deity) guide.

Over centuries the Spanish monarchy managed to not only be a major player in Europe, but to establish an empire where the sun never sets. As early as June 1494 the Portuguese and Spanish had split the globe into two hemispheres with the Portuguese claiming the land between Brazil in the West and present day Indonesia in the East and the Spanish gaining exclusive rights to establish colonies anywhere else, ranging from west of Brazil to the most eastern islands in Asia.

The following Steam Achievement Guide is basically the same as Conquest of The New World – Tea and Crumpets for Everyone Steam Achievement Guide, which describes how to succeed with England. The same strategy was already validated with Conquest of The New World – Tout le Monde Francophone? Steam Achievement Guide and now, winning on Deity, with an even higher score will be my final validation. If you need more details on something, please check out the English strategy first. I will use this guide to point out small variations and improvements to the aforementioned strategy.

Part 1: Dominate Europe

Chapter 1: Initial Build Order and Research

The AI in this scenario is dominant as always. So as usually we need to defeat the main AI players as early as possible.

Now in Conquest of the New World, European Nations can not declare war on each other until the discovery of Piracy. This means in order to get the Siglo de Oro, you need two things:

  1. Direct your Research straight to Piracy
  2. Meanwhile build a military strong enough to capture those European capitals

The initial build order shows exactly that focus on Production improvements and right after only units:

Seville no 2nd city founded the first 75 turns
1. Ironworks (5)
2. Forge (8)
3. Cargo Ship 1 (11)
4. Navigation School (16)
5. Cargo Ship 2 (18)
6. Seaport (bought with Gold from unique ability)
7. Cargo Ship 3 (26)
8. Cargo Ship 4 (28)
9. Galleas 1 (29)
10. Galleas 2 (31)
11. Galleas 3, 4, 5, 6
12. University of Oxford (turn 47, Researching “Warships”)

Upgrade to Frigates

2x Trebuchets
2x Conquistadores
Researched Piracy turn 48

This build order pretty much guarantees to by turn 54 have an army of:

  • 6 Frigates
  • 4 Privateers
  • 2 Trebuchets
  • 3 Conquistadors

After conquering Portugal, this grew to 7 Frigates and 6 Privateers, so +30%.


  1. Navigation (10)
  2. Trapping (15)
  3. Calendar (18)
  4. Printing Press (24)
  5. Education (29, starting University of Oxford ASAP)
  6. Imperialism (34)
  7. Piracy (48)
  8. Gunpowder
  9. Chemistry
  10. Economics (72)
  11. Banking
  12. Religious Orders
  13. Treasure Fleet
  14. Advanced Piracy (111)

The Spanish Unique Ability — Seven Cities of Gold

Gold bonus for discovering a Natural Wonder (Bonus enhanced if first to discover it). Culture, Happiness, and Tile Yields from Natural Wonders doubled.

This bonus is great: You’ll most likely discover at least 2-3 natural wonders and will receive around 1000 Gold. In my game I bought a seaport further improving production in Seville, thus speeding up the European conquest.

European Social Policies

Timing is essential: First getting the production bonuses is great for building the army. Only then adding City Sack and Ransom supports the European conquest.

Chapter 2: Conquest of Europe

With the army listed above it was as planned super easy to gain my Siglo de Oro by conquering the European capitals. Already in turn 52 I declared war on Portugal. Lisbon fell in turn 58, granting more land for Seville. A fact that will make Spain and Portugal more powerful when you play them and conquer the respective other.

Making peace with Portugal turn 59 I headed straight for England: I picked them next, because with their unique ability, making their navy even more powerful they had to be taken out as quickly as possible. They already were on a good way building their navy so it took several until Plymouth got captured (turn 65)! It granted me another 3 treasures (so 3x 25VP and 300G). In the peace deal in turn 67 I only got 9 Gold per turn.

Before heading for the Netherlands I needed to ally their cultured City States for the Culture boost. Taking this time was okay, since shipping to the Netherlands always takes a bit longer due to the English Channel protecting them from big fleets. After healing all units and bringing them in position, I declared war in turn 70. Amsterdam fell in 2 turns (71) and in turn 76 we had peace.

During the peace negotiations with the Dutch, war with France was already going on: La Rochelle fell in turn 78. War with France was going on for some longer as France already had quite some colonies on the other side of the Atlantic.

Playing Spain, Europe was liberated only in turn 78, some turns later than in the France game. Still: With Seville getting stronger than any other European capital due to taking the tiles from Lisbon, this will be the most successful playthrough of the Conquest of the New World Scenario!

Part 2: Conquest of the New World

Chapter 3: Defeating the European’s Colonies

Having a Northern Archipelago is the best that can happen: All cities are accessible by our battle fleet. In this game, I took one French city, made peace, healed and went for the Dutch cities. In a peace treaty I demanded their continental cities (because they’re harder to conquer). Then I went for France and England again and after 10 turns declared war on the Netherlands for the third time. Capturing their last northern city, I demanded their second-last continental city, leaving them only a tiny naval base easily conquered in the 4th Spanish-Dutch War.

Chapter 4: The Native Americans

Other than playing England and France in the first two European games, I won’t provide a detailed log of the conquest. It’s very individual per map anyways, so I’ll just use the following gallery to highlight some of the main aspects like:

  • promoting battleships for Logistics (2 attacks) and Range as this gives you 4 Range when upgrading to Ships of the Line
  • saving treasures until you get the Conquest of the New World Social Policy as this gives you double VP from treasures
  • bribing the Native Americans to war against each other as every unit they kill themselves is one you won’t have to kill (yes, killing units grants gold, but time is of the essence, when aiming on defeating them)

From my first war with the Inca I got 11 GPT for making peace. The Shoshone gave me 24 GPT. I used only a fraction of it (7 GPT each) to first bribe the Aztecs against the Maya (whose capital I took in turn 113) and later against the Iroquois.

With Veteran Ships of the Line (Range 4 and Logistics) I was able to bombard all their cities, even those 5 tiles inland, from a coastal city on hills. This and a good rotation of ships dealt with the Iroquois army very quickly.

Same worked for the Shoshone, who until late in the game lead the scoreboard. But even their powerful navy fell victim to my veteran Privateers and Ships of the Line.

Eventually playing Spain I got the highest score of any Conquest of the New World games so far: Almost 8000 VP!


Siglo de Oro (Deity) – Conclusion

Civilization 5 Conquest of the New World Spain Deity ExpansionThis last European Steam Achievement playthrough for Conquest of the New World went super smoothly. Other than playing France I never was worried about having enough time to score VP. It worked and it’s been fun as usually. Challenging? Not so much. The amazing 7900 score shows as much! 🙂

The strategy is proven. Most likely the Netherlands and Portugal matches will only result in image galleries.

  1. You think your 7900 VP can’t be topped? Maybe on Deity, this is really nearly untoppable. On *Settler* this CAN be topped: I played on Settler as English Empire, and followed your strategy where I could:
    * My America map had a narrow pass (opportunity to build a “Panama Canal” when placing a city on it) in Central America, and it was possible to sail from Atlantic to Pacific between South America and Antarctica (there existed no Northwest Passage)
    * At the beginning I built up buildings and units exactly in the order given by you
    * Researched for Piracy quickly (I think I had it in turn 52)
    * I had not a single cultural city state on the map, so I was quite behind your social policy roadmap (I unlocked them in the order given in your England Strategy guide, but I didn’t make it to the “Conquest of the new world”-policiy, so I didn’t get double gold for any treasure)
    * I founded exactly one city – in Central America, where I had the opportunity to get a “Panama Canal” (I did not found any other city until the end of the game)
    * When I researched Piracy and had my fleet in position, I conquered Europe in the order Netherlends – Portugal – Spain – France – before heading to America
    * I annexed every European City which I had conquered as soon as I had enough money to buy a Courtyard
    * On the way to America I conquered and annexed a Duch city on an Island with the Belize Barrier Reef in the City Radius (I shouldn’t have annexed this one)
    * Next I conquered all European colonies in North America, while continuing to build some Frigates, Privateers, Conquistadores and Cannons. I annexed a Duch City (New Amsterdam) on a nice place on the North Coast of North America, a and a second city quite south (I think it was a Portugaise colony). I left almost all other cities as puppets; I did NOT raze any city. (on Settler, I have the luxury to have enough happiness). Of course, New Amsterdam built (or bought) a harbour quite early and their workers started to build roads to the nearest cities quite soon.
    * In annexed cities I built / bought production buildings and cultural buildings as soon as possible – and I bought a “Meeting House?” (what is the English name of the Protestant “monestary”? as soon as possible in every annexed city
    * I used three Admirals to get the VP for 1st, 2nd and 3rd place for discovering China
    * I started to attack the Native Empires – and annexed one last city in the Southeast of North America (I had to quickly buy some defense units there) – This was the last city I annexed
    * While conquering the Natives, I tried to capture as many workers as possible – these workers were quite busy to build roads
    * I divided my fleets and armies between North and South Americas to simultanously conquer Native Empires in the North and South. I had conquered the last native city approx. 18 turns before the end of the game
    * I have built quite a few NAOs in my European cities (and also a few in my Central American city) and moved them to China
    * I managed to connect every city in the Americas to my road network (and of course, I had more then one harbour in America). With a Bank and Stock Exchange (and Chocolate Houses where possible) in every annexed city, I had 1295 gold per turn in the penultimate turn of the game.
    * 1 turn before the end I had 8134 VP (as I said – on Settler), and at the end I had 8280 VP. I am surprised that there is no penalty (i.e. getting less VP) for easy games in this scenario!

  2. So the gold reward for finding NWs is boosted? Or you somehow find them before the natives? 1K usually means first to find 2 which i never managed to do…
    Anyway seeing the map timeline depopulating the continent feels, quite satisfying. I usually tries to resettle the area to prevent barbs though.
    Looking forward to the next guide!

    1. Not sure about the reward for Spain. I was thinking that you’ll get 500G regardless of finding it first or not. Just the plain discovery counts, I think.
      Resettling is quite tricky on Deity, since every new city is a serious drain on Happiness 🙂 Thus I only resettle where I find many Luxury resources I still need in as few places as possible.

      The next guide will only be ready in 2018. But so far I can say: I’m having good chances in winning on Deity playing the Aztecs! Merry Christmas, happy holidays!
