Power projection

From Europa Universalis 4 Wiki

Power Projection is a mechanic which rewards nations for acting aggressively towards their Rivals. It encourages nations to have long-lasting feuds and to work against worthy adversaries. Aggressive acts include embargoing, declaring war, taking provinces, subsidizing enemies of rivals, and sending privateers. Its value is capped at +100.

Subject nations, except tributaries and daimyos, cannot have rivals and hence cannot get power projection.


Power Projection.png Power projection is gained through static effects that last until cancelled and event modifiers which decay over time. All event modifiers decay at a rate of −1/+1 power projection per year and are counted for each rival separately (Insulting a rival is the only notable exception here). Event modifiers do stack, but are capped at a maximum value. Everything exceeding this value is lost.

Example: 23 power projection is left from eclipsing rivals. Eclipsing another one would add another 10 power projection, potentially resulting in 23 + 10 = 33 power projection. However the value is capped at 30, so 3 power projection is lost and the value is set to 30, decaying at the normal rate of −1 power projection per year.

Factor Amount Maximum
Long-time rivals +1/year +5 per rival
Embargoing a rival Up to +10 depending on the embargo's impact on the rival's trade
Subsidizing a rival's war opponent +0.5 per percent of total income given, while the war lasts
Privateering in a trade node where a rival has trade power Up to +10 depending on impact on the rival's trade
Rights of Man.png Great power +10 to +25 according to rank
Mandate of Heaven.png Completed age objective +3 per objective
Declaring a war against a rival +10 +20
Honouring call to arms with a rival as war leader +10 +20
Taking provinces from a rival or giving them to a vassal in peace +0.5 per development +100
Signing a peace in which a rival loses provinces +0.5 per development +100
Vassalizing a rival +0.5 per development +10
Insulting a rival while not in a truce +5 +5
Dharma.png Scornfully insulting a rival while not in a truce +10 +10[Note 1]
Humiliate/Show strength +30 +30
Eclipsing a rival +10 +30
Supporting rebels in a rival +50, modified by the percentage of income used by the supporter 50
Empty rival slot −1 per year[Note 2] −20 per empty slot[Note 2]
Dishonouring a call to arms against a rival −20 −20
Losing provinces to a rival −0.5 per development −100
Being humiliated/shown strength −30 −30
  1. Doesn't stack with regular insults.
  2. 2.0 2.1 If there are fewer than three eligible countries that are not allies, the extra empty slots don't contribute to the penalty.

If a rival is replaced, completely conquered or ceases to be an eligible rival, all static effects gained against that rival will be lost; except for replacement, the loss power projection is generally compensated by the other factors that apply (conquest, losing provinces, vassalizing, and eclipsing). Power projection resulting from event modifiers is not lost, and continues to decay normally.


Having positive power projection provides several scaling bonuses. There is no penalty for having negative power projection; it is capped at 0. For each point, the following bonuses are given:[1]

Trade power.png +0.2% Global trade power
Prestige.png +0.005 Yearly prestige
Morale of armies.png +0.1% Morale of armies

Horde unity +0.005 Yearly horde unity

Having at least 25 power projection gives:[2]
