A march is a military orientated subject nation, which receives bonuses to its army, navy and forts at a cost of paying no taxes to its overlord and being more difficult to annex. Marches are more helpful subjects in wars, and can make an excellent buffer state between an overlord and its enemies.

Benefits of a March[edit | edit source]

A march doesn't pay taxes to their suzerain and cannot be annexed as long as they are designated a march. In exchange, they have Liberty desire.png-15% Liberty Desire and receive the following military bonuses:

Creating a March[edit | edit source]

Marches are created from a Vassal.png vassal via the "Designate March" button under the "Influence actions" section of the vassal's diplomacy window. Vassals are usually keen to become marches, and will sometimes ask their overlord to make them one. As of the Common Sense DLC, there is a -1000 malus towards an overlord accepting a request from a vassal to become a march if the vassal is next to colonizable territory, not bordering any of the overlord's rivals or enemies, or the vassal is in the overlord's culture group.

Although Art of War is required to designate a march, sometimes it is possible to have a march subject without the DLC.

  • Flag of Ottomans Ottomans starts with

Revoking a March[edit | edit source]

The status of a march can be revoked for the price of Stability.png −1 stability and Icon diplomacy relations.png −50 relations, decaying at a base rate of 2 per year. Revoking a march returns the subject to vassalage, allowing diplomatic annexation by the overlord 10 years after the revocation. Note that the stability cost penalty can be negated by completing the Diplomatic idea group.
