A province is an administrative division of land in Imperator: Rome.

Provinces are groupings of territories, and are themselves grouped into regions.

Province mechanics

  • Each province has access to the trade goods produced in its territories, and can have a set number of import routes to bring in goods from other provinces.
  • Each province has a governor policy.
  • Each province has a loyalty value.
  • Each province has a food supply and food capacity.
  • Each province has a capital, can be changed spending 25 political influence.

Provincial investments

Provinces can be improved repeatedly with investments for 80 Political Influence each. The cost can be reduced by heritages and technological advances.

Each investment takes 2 years to prepare and reduces the output of the province by 1% during this process. The resulting effects are permanent as long as the province is inhabited and the owner isn't changed.

All 4 types of investments can be applied to the same province, unlimited amount of times.

  • Install Provincial Procurators: 4% Population Output and 0.01 Monthly Province Loyalty
  • Promote Infrastructure Spending: +1 Building Slot.
  • Entice Business Investments: +1 Import Routes
  • Make Religious Endowments: +3% State Religion Happiness in Province

Sparta with Magna Graecia gets 2 unique investments.

Capital province

The province with the country's capital is its capital province.

The capital province is always loyal and has extra import routes. A trade good surplus in the capital province also applies a nationwide capital surplus modifier.

Each pop in the capital province has a +25% output modifier (stacking with the capital city and region modifiers).

Provincial loyalty

Every province has a loyalty value, representing how happy it is with the central government.

Loyalty changes monthly; it is lowered by unrest in the territories, proportional to their population. Assigning regional troops to the governor may lower unrest by up to -4.

Loyalty increases from:

  • the governor's loyalty (+0.25 at 100 loyalty)
  • the Harsh Treatment policy (+0.3 at 9 finesse)
  • the military investments (Provincial Procurators) (+0.01 per level)
  • Courts of Law in cities (+0.02 each, adjusted by population size)
  • 0 unrest (+0.1 adj. by population size)


At 33% loyalty the province is considered disloyal.

Territories in disloyal provinces can't be interacted with, blocking building construction, pop movement and cohort recruitment.

If a significant portion of the nation's population lives in disloyal provinces, the nation will progress towards a rebellion.

Governor policies

All policy effects are modified by the governor's Civic power.png Finesse.

The values below are given for 9 Civic power.png.

At 0 Civic power.png the effects are reduced by 90% Each point of Civic power.png above 9 increases them by 10%.
