Development is a province attribute, which replaces the former system of static base tax and manpower. There are three kinds of development in a province - base tax, production, and manpower, corresponding to administrative, diplomatic and military power respectively. Players with the Common Sense.png Common Sense DLC can increase province development values by using monarch power.

Province development is involved in some Age Objectives:

  • Having a cored province with at least 30 development is an objective in the Age of Discovery.
  • Having a capital with at least 50 development is an objective in the Age of Revolution.
  • Having a total development of at least 100 while the nation's capital is not in Europe, Asia and Africa is another objective in the Age of Discovery.
  • Having a subject with at least 250 development is another objective in the Age of Revolution.

Effects of development

A province gains per development level in:

Tax Base Icon.png Base tax:

Regiment recruit speed.png −1% Local recruitment time

Gold Icon.png +1 yearly tax income base

Production.png Production:

Local goods produced +0.2 Local goods produced
Local shipbuilding time.png −1% Local shipbuilding time

Local manpower modifier.png Manpower:

National garrison growth.png +1% Garrison growth

Manpower.png +250 maximum manpower

Irrespective of category, every point of development has the following effects on the individual province (note that only coastal provinces get sailor and naval force limit bonuses):

Possible number of buildings.png +0.1 Possible number of buildings
Supply limit modifier +2% Supply limit modifier
Local missionary strength.png −0.1% Local missionary strength
Land forcelimit.png +0.1 Land force limit
Naval forcelimit.png +0.1 Naval force limit
Sailors.png +30 Sailors
Local trade power.png +0.2 Local trade power
Possible Manchu banners (local) +0.066 Possible Manchu banners
  • Development cost.png+3% local development cost per point above 10 total development. This increase rises by 3% every 10 total development (+6% at 20, +9% at 30, etc.).
  • Province war score cost.png+1% Province warscore cost
  • Overextension.png+1% Province overextension value
  • Core-creation cost.png+10 Core creation cost
  • Diplomatic annexation cost+8 Diplomatic annexation cost
  • Culture icon.png Increases the percentage of the local province culture in the player's nation.
  • Estate loyalty If the province belongs to an estate, the estate's loyalty will increase as if it had been granted a 1 development province.
  • Institutions.png Increases the institution presence in the province by (new development level/6). This is capped at +10% increase.
  • Institutions.png Most institution spread modifiers scale linearly with province development.
  • Removes 5% Devastation icon.pngdevastation(with adjustment based on local autonomy).

Development levels over 30 no longer contribute to higher coring and culture conversion costs. For every 10 levels of development, a province gets an additional building slot.

In addition, the nation gains Caravan power.png+1 caravan power for each 3 total development levels, up to 50.

Developing a province

Development cost tooltip.

Monarch points (Administrative power.png, Diplomatic power.png or Military power.png) can be used to increase base tax, production, and manpower values, respectively. A province's base tax, production or manpower cannot be increased if its value is already more than that of the other two combined (for example, if the province's base tax is 3 and production/manpower 1 each, only an improvement of production or manpower is possible). In other words, the cap for one development type is equal to the other 2 plus 1.

Base cost

The base cost for developing a province is 50 monarch points. Development efficiency from administrative technology affects the base cost by additional −10% at level 17, 23 and 27.

Development cost modifiers

The development cost modifiers influence how much it costs to develop a province. The cost to develop provinces increases by +3% per point above 10 total development. This modifier itself increases by 3 for every 10 total development. For example, a province upgrading from total development level 30 to 31 will have "Development: Development cost.png+99%" modifier.

All development cost modifiers are applied in an additive fashion.

Note that without the Common Sense.pngCommon Sense’ DLC the modifiers are exchanged. (National) Development cost modifiers are replaced by a (national) goods produced modifier of the same amount with reversed sign. Local development cost modifiers are replaced by tax income of a tenth with reversed sign.

Stacking development cost modifiers

Developing a province to get an institution can be expensive in terms of monarch points; it is recommended that the player choose to develop a province with multiple modifiers that stack. To be specific, to attain the maximal reduction in development cost, the player should choose to locate their capital in a province with a Centre of Trade, temperate climate, farmlands, and that produces cloth or cotton. The following provinces have this combination of modifiers: Antwerp, Baghdad, Constantinople, London, and Prague. These provinces have a cumulative reduction in developing cost of -20% (-5% from farmlands, -5% from CoT, -10% from cloth/cotton).

Ideas and traditions

These modifiers lower the cost for developing a province. Without the Common Sense.png Common Sense DLC, development is not possible; these modifiers are replaced with a Goods produced modifier.png goods produced modifier of the same size.

Exploiting development

A province can be exploited for short-term benefits by permanently reducing its development by 1.

  • Exploit Tax Base Icon.png Base Tax to gain 60 months' worth of that province's tax income
  • Exploit Production.png Production to gain 60 months' worth of that province's sailors
  • Exploit Manpower.png Base Manpower to gain 60 months' worth of that province's manpower

A province has to have at least 2 development in a category for it to be exploitable, and is required to have at least a territorial core. A province cannot be exploited within the 20 years following its last exploitation, even if it changes owners.

AI behavior

AI generally will not develop provinces to more than original development * 2 or 10 development, whichever is higher. These numbers can be changed in defines.[1]

The exception to this rule emerges when the AI develops one province for the purposes of institution spread, introduced in Patch 1.18. At this time the exact behaviour of the AI regarding this is not well understood. The AI does not develop provinces anywhere as efficiently as a human player may do so.[2]
