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 MarchEdit

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  -15% Liberty Desire and receive the following military bonuses:

Military bonusesEdit

  +25% National manpower modifier
  +30% Land force limit modifier
  +30% Naval force limit modifier
  +20% Fort defense
  −20% Fort maintenance
  +20% Manpower recovery speed
  −20% Land maintenance modifier
  −20% Naval maintenance modifier

A march only receives these bonuses as long as it has less than 25% of the  development of its overlord.

March force limit contributionEdit

Marches increase the suzerain's   land force limit by 2, as opposed to 1 from a vassal. This contribution can be increased by the following.

Creating a MarchEdit

Marches are created from a   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.

  •   Ottomans starts with
    •   Crimea as a march from 1 May 1478 to 20 July 1774.
    •   Tripoli as a march from 1516 to 1710.
    •   Algiers as a march from 1516 to 1821.
    •   Tunis as a march from 1593 to 1704.

Revoking a MarchEdit

The status of a march can be revoked for the price of   −1 stability and   −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.
