Monarch power is a measure of a ruler's influence and ability to govern their country. It is a central mechanic in Europa Universalis IV, influencing how effective a country is at technological improvements, diplomatic relations, and infrastructure investments.
There are three types of monarch power:
- Administrative Power represents the internal organization and development of a country.
- Diplomatic Power represents the external influence of a country, including diplomacy, naval power, trade, exploration or colonization.
- Military Power represents innovations and leadership for armies.

Generating monarch power
Monarch power is generated at the beginning of each month. There are four sources of monarch power: ruler, country, advisors, and power projection. Based on these factors, the monarch power gain of each type can range from 2 to 15 a month.
A country can only store an amount of monarch power of each type equal to 999 modified by the technology cost modifier of its technology group.
A country can have an advisor for each power type, providing 1–3 points a month. An advisor's maintenance cost starts at 1 ducat a month for a +1 point advisor at the game's starting date. The cost increases quadratically with advisor skill level, and slowly inflates by 0.5% per game year. It is also modified by inflation.
All tech groups have a base power production of 3 points per month. Prior to patch 1.7, low tech group nations also produced fewer points (1–2).
Having at least 50 power projection provides an extra +1 points a month for all monarch power types.
Increasing monarch power
There are no percentage modifiers to monarch power, though there are effects that modify the cost of specific actions that require monarch power. The most flexible of these are advisor choices; a rich country could temporarily hire an appropriate advisor to get a discount on an immediate purchase.
Monarch power gains are much more independent of the size of a country than other resources such as monetary income and size of military, but large countries often require expending more power on additional provinces and military maneuvers. However, there are a few ways of increasing a country's monarch power, particularly if the country has some other resource to spare:
- Hiring more skilled advisors increases monarch power production at the cost of ducats.
- Many random events have an option to gain or lose monarch power. Often (but not always) this is offset with a corresponding loss or gain of some other resource.
- Republics can re-elect leaders to gain skill in each category at the cost of republican tradition, or elect a different ruler for a different distribution of skills. Other types of government can try to manipulate the heir mechanics through random events, or in the extreme case, arranging for the death of an unwanted ruler or heir in combat.
- Increasing and maintaining power projection of at least 50 by maintaining and acting aggressively towards rivals provides a bonus, at the cost of long-running and often bloody feuds.
- With The Cossacks DLC, steppe hordes can gain monarch power by razing non-core provinces, reducing its development. This gives +25 power of the appropriate category for each point of development lost.
- If an estate has an influence of at least 25 and loyalty of at least 30 then you can also demand support from it. The estates give 50 monarch points at 25 influence and an additional 50 up to a maximum of 200 for every 25 influence above 25. Clergy give administrative points, nobility give military points and the burghers give diplomatic points.
- With Rights of Man active, great powers gain a diplomatic option called Influence Nation that allows them to pay one year's worth of income to grant +1 monarch power to a target independent non-great power nation in their weakest category for 10 years.
Some situations can cause a monthly loss of monarch points:
- Too many diplomatic relationships: having treaties with more countries than a nation's diplomatic relations cap will result in a monthly loss of diplomatic power, equal to the numbers of relations above the limit. The number of diplomatic relation slots can be increased through selecting idea groups, national ideas, or other modifiers.
- In the same way, having too many military leaders will also result in a monthly loss of military power, equal to the number of leaders above the limit. The number of military leaders without upkeep can be increased by ideas, traditions, and policies, by increasing and maintaining power projection of at least 25, by increasing government rank to Empire with The Cossacks DLC, and other factors.
|Available only with the Res Publica DLC or the Common Sense DLC enabled.|
Countries can set a national focus on any of the three monarch power types. The chosen monarch power type receives +2 per month (added to the base gain), while other two monarch power types decrease by one point -1 each month. A focus does not change the overall amount of monarch power generated per month, it merely redistributes it. How often the national focus can be removed or changed depends on the country's Government rank: Duchy = 25 years, Kingdom = 20 years, Empire = 15 years.
This allows a country to catch up faster if behind in a specific technology (especially with Military technology this is a huge impact) or to fill out ideas more quickly. Always be aware of the country's ruler though, because they still play an important role. For example, the current ruler may have very good administrative skill, whereas the heir may be unbalanced and only have 1 or even 0 administrative skill. Due to this, and particularly since changing the national focus takes a long time, planning ahead is essential.
