Province
A province is an administrative division of land in Imperator: Rome, formed by groupings of territories and themselves grouped into regions. Ingame, many important mechanics such as food, trade, and
territorial loyalty are handled at the provincial level, as well as certain diplomatic actions such as fabricating claims and peace term demands.
Provincial loyalty[edit | edit source]
Every province has a province loyalty value, representing the local level of support for the central government and the willingness of the province to follow its orders. Disloyal provinces will refuse to follow orders from the capital and may eventually revolt in a rebellion or join a
civil war - managing the loyalty of provinces is one of the most important aspects of running an empire.
Province loyalty changes monthly depending on the sum of all province loyalty modifiers. Territory Provincial Loyalty modifiers affect individual territories and are scaled to the territory's
relative population in the province before being applied to the territory's province's loyalty,
Local Provincial Loyalty modifiers are applied to provinces and affecting its loyalty directly, and
Provincial Loyalty modifiers affect all owned provinces in the country.
Unrest - itself driven largely by
the happiness of the population - is the main factor that decreases
province loyalty, giving
-0.08 territory provincial loyalty for every point of
unrest. As territory provincial loyalty is scaled to the share of the province's
population in the territory, large cities will therefore have a much greater effect on province loyalty than lightly populated settlements. Governor
corruption (-0.25 at
100 corruption) as well as lacking a governor to administer the region altogether (-0.35) will also give a significant malus to
province loyalty. The main way to reduce province loyalty loss is by tackling the source, such as building
forts or increasing
pop happiness to reduce
unrest or by replacing corrupt governors.
If dealing with the source of loyalty loss is not enough, monthly province loyalty can also be increased by:
- +0.004 for each point of
governor loyalty above 50 (to a maximum of +0.20 at
100 loyalty)
- +0.03 per governor
finesse, plus +0.03 base when using the Harsh Treatment governor policy
- +0.01 for each level of the
Provincial Procurators province investment
- +0.10 (maximum) from territories with
0 unrest, scaled according to the share of the province's
population in the territory
- +0.05 (maximum) for each
Great Temple and
Grand Theater in a
city, scaled according to the share of the province's
population in the territory
- +0.01 (maximum) for each
Court of Law in a
city, scaled according to the share of the province's
population in the territory
- +0.25 for 2 years after using the
Anabasis unit ability
- +0.03 from passive modifiers of various deities (+0.0375 if their
holy site is owned)
- +0.04 per
100% omen power for various omens (+0.05 per
100% omen power if their
holy site is owned)
- +0.05 with the
Central Urban Spaces national idea
- +0.02 with the
Petition of Minorities
Civic invention
- +0.02 with the
Reduced Governorship
Religious invention
- +0.02/+0.04/+0.07/+0.10 for a
great wonder with the
Government Traditions effect, based on the effect's tier
- +0.05 with a
ruler with the
Blood of Seleukos trait
In addition to its monthly loyalty change effect, the Anabasis unit ability will also immediately increase the province's loyalty by 5.
Once a province's loyalty drops below 33, the province is considered disloyal and will refuse follow orders from the central government. Territories in disloyal provinces cannot be interacted with, blocking building construction and pop movement. Changing governor policy, however, is still allowed (as long as the governor is still loyal).
If a province's loyalty drops all the way down to 0, it will immediately
rebel. A new state will be formed from the province (or possibly a previously existing one that has been annexed), and it will either declare a independence war or join an ongoing one if there is a nearby province that has already rebelled. While the rebellion of a single province is unlikely to be successful, widespread discontent and unhappiness can be dangerous for even the strongest empires.
Province capital[edit | edit source]
- Main article: Province capital
Every province has a province capital for each country that controls part of it, representing the center of the local administration. The province capital gets significant bonuses and is generally the largest and most important territory in the province, determining who controls the province during a war and being one of the main recipients of
enslaved pops. If desired, the province capital can be moved during peacetime to a better location at the cost of
province loyalty.
Capital province[edit | edit source]
The province with the country's capital is considered its capital province.
Every pop in the capital province has a +10% output modifier (stacking with the capital city and capital region modifiers). In addition, the capital province is fixed at
100 loyalty regardless of any province loyalty modifiers and so will never rebel.
The capital province is also where the special countrywide capital trade good surplus bonuses are gained. As the target of the capital trade routes modifier, which usually has contributions from the default commerce policy and country ranks as well as usually being the most populous province with a high population of
nobles and
citizens, this together means the capital province is usually the center of trade in a country with a large variety of imported trade goods.
Provincial investments[edit | edit source]
Provinces can be improved repeatedly with province investments to improve the administration and infrastructure of the province. Province investments have a base cost of 80 political influence each, modified by the specific province investment cost modifiers (
military provincial investment cost,
civic provincial investment cost,
oratory provincial investment cost, and
religious provincial investment cost) that can be reduced by heritages and various
inventions. There is also an additional cost of
20 gold for every currently existing investment in the province, including others of a different type, which is not affected by the provincial investment cost modifiers. Each investment takes 6 months to prepare and reduces the
output of the province by 1% during the process. The resulting effects are permanent as long as the province remains colonized and the owner does not change. Province investments cannot be cancelled once started, and only one investment can be made in a province at a time. Once a province investment is finished, a notification event will appear in the event queue.
It is also possible to get free province investments from forming nations, adopting certain
inventions and
military traditions, and as a reward for certain mission tasks, which allows a country to make a provincial investment without spending any
political influence or
gold. Note that the 6-month duration to implement the investment still applies.
All 4 types of investments can be applied to the same province an unlimited amount of times.
Install Provincial Procurators (Military):
+0.01 Local Provincial Loyalty and
+1 Fort Infrastructure Capacity
Promote Infrastructure Spending (Civic):
+2.50% Population Capacity
Entice Business Investments (Oratory):
+1 Local Import Routes
Make Religious Endowments (Religious):
+1 Local City Building Slots
With the Magna Graecia DLC, Sparta gets two unique province investments for the military and religious slots, replacing the standard province investments:
Free Helots (Civic):
+1.50% Population Capacity,
+2% Integrated Culture Happiness, and
+4% Local Freemen Output
Commission Heroic Frieze (Religious):
+4% Supply Limit and
+3% Local Citizen Output
Governor policies[edit | edit source]
Every province can have a governor policy set which determines the priority of the province's administration. Governor policies allow a country to extract more from a province's population, deal with
unrest by increasing
population happiness or cracking down on the population, build up the
civilization value of the province's territories, and more.
When a governor is assigned, they chose a random policy based on the factors listed in the Chance column (with a base chance of 0). This includes directly reassigning a governor without having a vacancy first. As long as the region has a governor, the policy can be changed at a base cost of 10 political influence, modified by the
change governor policy cost modifier. Changing governor policy manually, except for in the
capital region/governorship, also gives
tyranny based on the current ruler's popularity, scaling between
1.25 at
0 ruler popularity to
0.25 at
100.
All policy effects are modified by the governor's Finesse, with the values below are given for the baseline level of
9 finesse. Each point of the governor's
finesse above 9 increases the modifier by 10%, while each point below decreases it 10% to a minimum value of 10% of the base. This is described by the equation below:
Domestic policy | State • Attributes • Characters • Civil war • Culture • Government • Heritages • Laws • National ideas • Position • Rebellion • Religion • Technology |
Economic policy | Buildings and Infrastructure • Economy • Food • Great wonders • Population • Trade • Trade goods |
Territories | Region • Province • Territories • Colonization • Holding |
Military | Military traditions • Army • Distinction • Land units • Land warfare • Siege • Naval warfare |
Foreign policy | Treaties • Warfare • Casus belli • Claim • Diplomacy • Subject nations • Barbarians |
