Region

The region mapmode

A region is the highest level of geographical organization in the game, formed by groupings of provinces.

Region mechanics

Each region can be administered by a governor, who gives various bonuses or maluses to all owned provinces and territories in the region based on their traits and attributes. Additionally, regions are the fundamental unit by which a country's levies and legions are raised and organized. Each region in a country has a certain army strength based on its non-slave integrated culture population, which be either raised as a levy under the command of the region's governor or recruited to form part of a legion based in that region.

Capital region

The region containing a nation's capital city is the nation's capital region. The capital region is always governed by the nation's ruler, with the effects of his/her attributes and traits applied to all provinces and territories in the capital region as if the ruler was a governor.

Every state/territory in the capital region gets the following modifiers:

• +0.05 Local Provincial Loyalty

Note that this modifier stacks with the modifiers for the capital province and territory.

As the capital region does not have a governor who takes a portion of the income, is more loyal than other regions of the state, and helps the ruler with their power base, full control is recommended before expansion elsewhere.

However, during a civil war, the territories where a rebelling character has holdings (even those within the capital region) will always join the rebels.
