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

Creating a March
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.

- 奥斯曼 starts with
- Any eligible country can get 哈卜尚 as a march through the Siddi State of Habsan event.
- 奥斯曼 can get 克里米亚 as a march through the Fate of the Crimean Khanate event.
Revoking a March
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 after 10 years.Note that the stability cost penalty can be negated by completing the Diplomatic idea group.
In addition to the generic subject interactions, marches have the following unique options:
