For a list of all provinces, see List of provinces.

In Europa Universalis IV, the world is divided into continents, regions, areas, and provinces. Provinces are the smallest of these divisions and are the basic unit of the game mechanics. They contribute to a nation's tax, manpower, unrest, overextension, and trade.

Each province comprises a small geographic region, with a town or city at its center, although cities currently have no functionality outside of aesthetics.

There are 3137 provinces in total.


Terms and mechanicsEdit

Provinces are the heart of any nation in Europa Universalis IV. They provide income, manpower, and trade goods.


Main article: Development

Development is the measure of a province wealth and productivity. The level of development of a province contributes to local trade power, land and naval force limits, supply limit modifier and the total number of buildings that can be built in a province. Development is further divided into base tax, production and manpower. Each can be improved further with the appropriate monarch points.


Main article: Tax

Each province has a base tax, roughly corresponding to the population and wealth of the area. The amount shown is the tax earned each month from that province, after all the modifiers have been accounted for.


Main articles: Production, Trade goods

Each province produces a specific type of resource or trade good. See Trade for a complete list of trade goods. The figure given ingame is the monthly production income. Production efficiency further increases the income received.


Main article: Manpower

Every province contributes a certain amount of manpower to the manpower pool of a nation. This is affected by the province manpower development level, and are modified by ideas, government type and buildings.


Main article: Land warfare

Provinces can be defended by forts. Provinces that lack a fort will fall easily to the enemy. Forts exert a Zone of Control around itself and surrounding provinces, and must be taken before an enemy army may pass through. In times of peace, a fort may be mothballed in order to save maintenance, at the cost of it falling into disrepair and possibly not being able to defend the province. Nations may start off with forts in strategic locations. Capital provinces without a fort starts with a special level 1 fort that does not exert Zone of Control around itself, and has a smaller garrison.


Main article: Trade

Related closely to production is trade. Each province produces a certain amount of trade power and contributes trade value to the trade node it is attached to.


Main article: Local autonomy

Autonomy represents the degree of control the government of the nation exerts over a province. The lower it is, the more control the government has. Autonomy determines how productive a province is to a nation.A province with 100 local autonomy won't pay tax and won't give manpower and trade power.


Main article: Rebellion

In troubled times, various parties may decide to rebel against the national government. This is represented in-game by unrest. The type of rebels that may appear are shown in the province screen, and also in the stability and expansion government tab. Unrest can also be lowered by increasing the local autonomy, but will decrease the income and manpower that province produces.


Provinces that have been besieged or occupied or where their owner has scorched the earth gain   devastation.

Devastation is expressed as a percentage: 0% indicates that no devastation is present in the province, while 100% represents an extreme amount of devastation.


The effects of devastation are scaled linearly according to the percentage value. At 100% devastation, a province would incur the following penalties:

  −100% Local goods produced modifier
  −50% Supply limit modifier
  −100% Institution spread
  +10% Local development cost
  −100% Manpower modifier
  −100% Sailors modifier
  −25% Local hostile movement speed
  −25% Local friendly movement speed

On the state level, prosperity cannot be achieved while any province in the state has any amount of devastation.

Causes and remediesEdit

Devastation changes according to the following factors:

+0.1 Under siege (even friendly)
+0.1 Under blockade (even friendly)
+0.2 Occupied
−0.08 Under its owner's control
−0.83 In the zone of control of a friendly active fort (not if occupied)
−0.25 Edict of Absolutism (requires   Mandate of Heaven)
−0.05 In states with Metropolitan (requires   Third Rome)

Looting a province increases devastation by significant (but unspecified) amounts, observed anywhere from +0.07 to +2.1. Once the province's loot is depleted, the devastation increase reverts to the usual +0.2 for being occupied.

Devastation can be manually removed by developing a province. Development removes devastation at 5% per point (with adjustment according to local autonomy).

Cores and claimsEdit

Main articles: Core, Claim

Cores represent the parts of the nation that it considers rightfully theirs. Cores belonging to nations that do not exist are greyed out. A province can have an unlimited amount of cores. A nation may claim another province through espionage or boundary disputes.

Culture and religionEdit

Main articles: Culture, Religion

Each province has a primary culture and religion. Provinces that have foreign cultures or do not share the state religion tend to be more rebellious and less productive.


Main article: Buildings

Nations may further develop their provinces by building improvements and infrastructure. The number of buildings that can be built in a province are limited by its development level.


Main article: Capital

Every nation in Europa Universalis IV has a capital province. The capital is considered the political center of the nation and should be defended at all costs. Capitals can be moved at the cost of 200 administrative points.

Main trading portEdit

Every nation has a main trading port province which is by default located in the same province as the capital. Trade is automatically collected in a nation's main trading port without the need to station a merchant there, and without suffering from the -50% total trade power cut suffered when collecting trade income in another node than the one of the main trading port.

Relocate main trading portEdit

The main trading port can be moved to another province at the cost of 200   diplomatic power. This enables countries to move their trade collection to richer trade nodes over the course of a game, without needing to move their capital city as well.

After the move, trade collection will automatically occur in the trade node which now contains the main trading port. Automatic collection will immediately cease in the original trade node.

Within a given trade node, the effects of the main trading port will be identical regardless of which province is chosen as the main trading port.

Main article: Island

Some provinces are considered islands or on an island which is important for some events, achievements and decisions.

Climate and weatherEdit

Each province has a climate and may experience winters and/or monsoon of varying severity. There are map modes for climate and weather.


The arctic climate is harsh, where there is not much large vegetation.

Arid provinces give:[2]

  %−10 Local settler increase
  −20% Supply limit modifier
  0%+1 Attrition for enemies
  +10% Local development cost


The tropical climate makes it very hard for new cities to grow, as diseases and heat are large obstacles.

Center of TradeEdit

With   Dharma, Centers of Trade (CoTs) can be upgraded or downgraded manually, but cannot be created or removed. However, some events (such as Growth of the port) allow a natural harbor to growing into a CoT. Manual management can be done in the building interface, where the CoT icon occupies 2  building slots. As a result, a province with a CoT can only build 10 buildings at most, rather than the usual maximum of 12 buildings.

The base cost to upgrade a CoT from level 1 to level 2 is 200 ducats, and the base cost from level 2 to level 3 is 1000 ducats.

You can only upgrade a CoT:

  • to level 2 and 3, if the province is part of a state or Trade Company.
  • to level 3: a nation may only have as many level 3 CoTs (World Port, and World Trade Center) as they have   merchants.

Downgrading a CoT will cost 10  prestige, but this option is available only if country has positive prestige. If a province changes ownership, via war or diplomatic actions, the level of the CoT will automatically drop by 1; if the province becomes a territory, the CoT automatically drops to the minimum level of 1.

For a list of all CoTs, see Economic list of provinces.

Religious centerEdit

The importance of this province as a Religious Center will make it very difficult to convert.

Religious centers have   −5% local missionary strength.[10] This modifier will only be active if the province currently has the religion the modifier is tied to:

  • Roma -  Catholic

States and territoriesEdit

Main article: States and territories

Within a country, each province is either part of a state or a territory. This distinction affects provinces in a variety of ways, such as by determining their minimum local autonomy.


Each province has a terrain type associated with it. These terrain types can have both positive and negative effects. Combat is affected majorily by terrain type and can even make the difference between glorious victory or shameful defeat. Terrain types and their corresponding positive/negative effects can be seen here:

Supply limit
Local defensiveness
Movement cost

Attacker penalty
Local development cost
  Glacial +2 +25% −1 +50%
  Farmlands +10 +10% −5%
  Forest +4 +25% −1 +20%
  Hills +5 +10% +40% −1 +25%
  Woods +6 +10% −1 +15%
  Mountain +4 +25% +50% −2 +35%
  Grasslands +8
  Jungle +5 +50% −1 +35%
  Marsh +5 +30% −1 +25%
  Desert +4 +5% +50%
  Coastal Desert +4 +35%
  Coastline +6 +15%
  Drylands +7 +5%
  Highlands +6 +10% +40% −1 +20%
  Savannah +6 +15%
  Steppes +6 +20%

Farmlands, grasslands, and drylands terrain also get +1 possible number of buildings


Both province and city names can be changed by left clicking on them in the province tab. With the Wealth of Nations expansion, province names can also be dynamic and scripted to be unique for either the province owner, the province culture or the province culture group (in that priority).
