Cusco is a landlocked country in the Andes region of western South America. They border Flag of Wanka Wanka to the north, and Flag of Colla Colla to the south. Cusco is the strongest of the Andean countries and is therefore suitable for forming Flag of Inca Inca and completing the Sun God achievement.



Main article: Cuscoan missions

Cusco has a unique (if small) mission tree focused on conquering a neighbor and potential rival,   Wanka.


Cusco has several country-specific historical events.[1]


 Fall of the Chanka & the Rise of Cusco

After years of struggles and having been dangerously close to total defeat by the Chankas in 1438 the kingdom of Cusco has now risen to a greater position than it has ever had previously. Having saved the kingdom, the young king Pachacuti went on to conquer the Chanka kingdom itself shortly afterwards, a state that for long times has exacted tribute not only from Cusco but from many of the states in the Andean world since the fall of the old Wari Empire.\nApart from marking Pachacuti as the greatest leader of the Cusco kingdom to date, the fall of the Chankas have given us access to their great treasury, a huge collection of gifts from neighbors and tributaries. This is exactly the kind of capital needed to buy the services necessary to reform and expand our kingdom. At this point nobody knows Pachacuti's plans but what is certain is that he has the means to steer Cusco in whichever direction he could wish.

 Cusco - Navel of the World

One of the first things on Pachacuti's agenda is the reshaping of Cusco. While our capital has served its purpose over the years it is in many ways no more than a rural village, often flooded by nearby rivers. Such a city is no longer fitting for a kingdom with ambitions such as ours. By creating a small model version of the city $MONARCH$ has drawn up plans for an entire redesign of the city, necessitating the complete evacuation of the city for the duration of the project.
While the manpower and material needed for this project are readily available inside our new borders mobilizing the various chiefs under our control entails a generous use of gifts and feasts. That is however a price we will have to pay for our new capital.

  • loses  25 diplomatic power.

Cusco (808) gets the modifier “Restructuring of Cusco” for 20 years, giving the following effects:

  •  0.5 yearly prestige,
  •  −15% local manpower modifier.
Our resources are better used for other things.
If Cusco has a stability of less than +3,
  • then it gains  1 stability,
  • else it gains  50 administrative power.

 Reconstruction of Cusco Complete

After almost 20 years the great project of restructuring Cusco is complete. The land has been leveled to create huge plazas and beautiful buildings erected, the nearby rivers have been led into canals.
The city is built to be the capital of an Empire rather than a small kingdom and is organized into four regions matching the way which we divide our realm in the Andes. The royal centre is located at the junction of the regions of Antisuyu, Qullasuyu, Kuntisuyu and Chinchaysuyu and these regions divide the Cusco valley as well as our empire.

Cusco (808) gets the modifier “Cusco” for the rest of the campaign, giving the following effects:

  •  0.5 yearly prestige,

 Machu Picchu

Just as the city of Cusco was in need of being reshaped in order to fit the wider ambition of the Cusco kingdom $MONARCH$ is now in need of a stately Estate to match the importance of his person and his lineage. On a mountain completely surrounded by the Urubamba river $MONARCH$ has planned the city of Machu Picchu, a royal retreat for his court and his Panaca and a beautiful place for a ruler of his magnitude to reside in.

Trigger conditions
  • This event fires only once.

 Tawantinsuyu, the Empire of the Incas

Once one of many small regional kingdoms our state now holds land in all the four regions of the Andes. Our kingdom has transformed into something greater, a mighty empire of many peoples united under a strong class of rulers. To our subjects we are simply their overlords, the Incas.

A good strategy for Cusco focuses on forming Inca and preparing for the arrival of western countries.

Playing primitiveEdit

Cusco and Inca are   Andean nations in the primitive technology group. Being primitive brings a series of downsides:

  • +50%   Development Cost in owned provinces;
  • cannot embrace   Institutions, even if they spawned in the provinces;
  • cannot build ships, or navy-related buildings;
  • start with Level 1 in   Administrative,   Diplomatic and   Military technology levels
  • does not have   Feudalism embraced.

Reforming the religionEdit

The Inti religion requires that all 5 government reforms be enacted, and that the player holds a core province that borders a neighbour who has embraced Feudalism in order to be able to reform. Each reform has to be enacted while having at least +1   Stability and 100 Authority. On enacting it, 3   pretender armies will spawn in random locations, the player's Authority will be reset to 0 and the player will take a -2   Stability hit. The player is thus encouraged to prepare beforehand by setting their Army Maintenance to 100% and activate their forts.

The only other ways to gain Authority, other than the monthly tick (based on total   Development of the player's nation), are events and lowering a province's Autonomy. The player is encouraged to take risks and shoot for the highest Authority gain option in events, which will usually come at the cost of rebel spawn or some   Local Unrest. On the other hand, raising   Autonomy in newly-conquered provinces or accepting outcomes that raise Autonomy will lower Authority. In a way, the player is able to exchange Authority and Autonomy in both ways.

If the player is going for the Sun God achievement it is advised to start with the "Expand the Mitma Policy" religious reform, that provides one   Colonist, as it will be the safer way to grasp high-development colonies before the western nations arrive, and the only way to move towards the eastern coast (where the colonizers will probably be). After that, army-related reforms will be good pick as the player will need to constantly fight rebels or neighboring countries.

It is strongly advised to avoid failing to put down a rebellion, as every successful revolt will remove 2 religious reforms from the player's progress, which can dramatically slow the reforming process and prove costly from a   Stability and   Administrative point of view.

Monarch points managementEdit

From the start date, the   Andean nations suffer a +50%   Technology cost malus for Feudalism not embraced. As time passes and more Institutions are spawned, the technology cost will continue to rise up to +50% per Institution not embraced. To further complicate matters, most of the area the player will have available is on mountain or jungle terrain type, with +25% to +35%   Development Cost penalty. Thus, it is extremely important that the player manages monarch points accordingly, to keep up with their neighbours but keep a hefty amount to be ready to reform when possible.

Since many game-long decisions as Cusco or Inca have the side effect of increasing the   Stability Cost (typically by +5%), the player is encouraged to take decisions that increase Stability when possible. The player will lose at least 10   Stability points due to reforms before being able to reform their religion. On the other hand, the Cusco event tree will trigger some unique events relevant to the capital's growth that will give permanent bonuses for the rest of the game. The player should consider carefully if the provided bonus (totalling +0.5   yearly Prestige and +1   yearly Legitimacy) outweight the immediate   Stability gain.

This being said, it is advised to at least purchase   Military Technology up to level 3, to be almost on par with neighbours (who will develop up to level 5 or 6) and avoid losing the last wars due to dramatic   Military Technology disadvantage. Depending on the player focus,   Administrative Tech 5 could also be hit to gain access to the first   Idea set, which may be Exploration for the added   Colonists and   Conquistadores or Economic to balance the high   Gold income and   Inflation increase.

The first years: unifying IncaEdit

Military ExpansionEdit

Although Cusco starts in a favorable position, it doesn't hold a sufficient edge over its neighbours that allows the player to expand recklessly. It is advised to focus on the southern nations beforehand, as the only other known gold mines in the area are held by   Colla and   Pacajes, which will usually rival one another. By playing with alliances and promising territories without upholding to the promises it's relatively easy to completely annex the southern half of the region in 10 years of less. To the north the web of alliances will probably be tighter, especially on the bottleneck   Wanka.   Ichma and   Huyla will usually be willing to accept alliance offers, but the player should be aware that in the end all alliances will have to be turned into annexations or vassalizations. All nations except   Quito will be annexable in one single 100% peace deal. Unfortunately, the only mission   Cusco gets in the way of local expansion is a permanent claim on   Wanka provinces, that would take less time and effort to build manually. As there aren't really many expansion routes or diplomatic options, the player may find worthy to keep diplomats spying on the nations that are going to be annexed, as spy network helps with aggressive expansion penalty and speeds up sieges.

After satisfying all the requirements to form   Inca, the player is encouraged to do so as soon as possible to benefit from the resulting Cultural Union and the expanded benefits the   Empire rank grants.

The player is encouraged to also annex   Muisca as soon as possible. In order to make this possible, the player must colonize a province bordering the nation and fabricate claims.

While there is no real haste to conquer the area, as it is isolated from the rest of the world, the player may want to speed up the process to acquire more development and bump yearly Authority generation as soon as possible. When the expansion is done the player should be gaining between 5 and 7 yearly Authority from development alone.

The player can combine the spy network construction with the "Transfer Subject"   Age of Discovery bonus to be able to quickly declare a war after the other as soon as they can border the new war target.


The first colonization target for the player should be on the pieces of land that connect the northern border to   Muisca on the southern border of Nieva. After that, the player should focus on reaching the eastern shores. The first colonies to be founded will be in Brazil, and will later spawn in La Plata or Columbia.

The player should be aware that, without   Diplomatic Technology or   Exploration or Expansion Ideas the   monthly settler increase will be the default +10, that will be offset by the -10 malus from the   Tropical modifier found on most available colonies. This will limit colony increase possibility to luck: for instance,   native assimilation given by the presence of a   colonist or by having a ruler with the   Expansionist trait.


Within the first years, the player should also see the first events related to the growth of Cusco as a capital city. As mentioned above, these events grant immediate benefits as opposed to lower, but everlasting ticking traits. The yearly   Legitimacy will only be useful if the player is able to reform to a neighbour under a   Monarchy government type: on the other hand, most of the countries that will neighbour Cusco or Inca when the time for reform is ripe will be Colonial Nations, which usually are   Republics. The player should keep this in mind and be prepared to either be picky about who to pick when reforming, or suffer internal disasters or revolutions that will overthrow the Republic to reinstate a (usually Despotic) Monarchy in order to benefit from this bonus.

In the same way, it is advised to avoid being swayed by events granting "support for Feudalism" in provinces: Cusco will not benefit from the support, and Feudalism will be automatically embraced once Cusco reforms its religion. The player can safely ignore this bonus when weighing their options.
