Province

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 cities, and can have a set number of import routes to bring in goods from other provinces.
Each province has a set governor policy.
Each province has a loyalty value.

Capital province

The province containing the nation's capital city is the nation's capital province.

The capital province has extra import routes, as it is affected by both the provincial import routes and the capital import routes modifiers. 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). All cities in the capital province also have +0.05% population growth.

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 province's territories, and increased by the skills of the governor of the province's region, as well as any troops assigned to them.

Territories in disloyal provinces can no longer be interacted with, blocking any pop actions and cohort recruitment. If a significant portion of the nation's population lives in disloyal provinces, the nation will progress towards rebellion or civil war.
