All countries have their governing capacity to rule their provinces. Governing capacity represents the ability of a nation to rule its lands efficiently. It is modified by government ranks, types, and reforms, along with administrative technology and estate privileges. Every province takes a share in governing capacity, based on its development. The share is halved if the province is assigned to a trade company and divided by four if it is in a territory. This reflects the historical difficulty of fully integrating every part of a large country, especially faraway or overseas lands. The player must decide which areas to turn into states, and which areas to leave as territories and trade companies.
Province governing capacity cost
Every province will contribute itself to governing capacity. The base value for each province is its total base development. It is modified by 100% for state, 50% for trade company and 25% for territory. Pirate republics get additional +75% governing cost penalty, while merchant republics get additional +25% governing cost in states and −25% governing cost in trade company provinces, making it 125% and 25% respectively.
Increasing governing capacity
Governing capacity represents the ability of a nation to rule its lands efficiently. Each nation has a base value of 200 governing capacity. Besides the nation can take Expand Administration action in government reform tab, giving +20 additional capacity by spending 20 reform progress (the cost will increase by +20% every time the action is taken). Additional modifiers are then applied as follows:
If the limit is reached, the country will get penalties. At 100% over limit:
|+100%||Stability cost modifier|
|+20%||Core creation cost|
|+50%||Aggressive expansion impact|
|−1||Militarization of state|
These are things that modifies governing capacity limit:
|+20||(unrecognized string “expand administration” for Template:Icon) Expand Administration (repeatable)|
| Adm Tech|
There are also ideas that change governing capacity:
A custom nation can have a national idea of up to +25% governing capacity.
