A vassal is a country under the power of other country, made by the player or by the AI.

Ways to get a vassal

  • Ultimatum.
  • Peace Negotiations.
  • Offer Vassalization.
  • Having a nonexistent country's capital (only AoC).
  • Creating a new country (Only AoH2)


The vassals will always have their lord's flag aside from their name, and the type of government's image will be modified. They can be called for fight in a war, like allies and it's much easier to make unions with them.

Lords can tax their vassals, which is called a Tribute. The lords can change the amount of taxation on their vassals, but this can affect the Liberty Desire. Any country can have a vassal, so a lord can be also a vassal from another country.

Since AoC 2, the vassals are independent from the lord (the player cannot control them), have their own wars and being capable of expanding.

Liberty Desire

A characteristic from AoC 2; every vassal has it: Liberty desire. Depending on the lord's relations before the vassalization, the initial Liberty Desire can be 0% when they had a good relationship (like +30) or 55% because of their very bad relationship (like -25). Is also Increased by High Tributes

Once that the Liberty Desire is very high, the lord will have the involuntary option of declare the vassal's independence or declare war.

Liberty Desire can change with actions made by the player, making a positive relationship and a more cheap tribute can decrease the Liberty Desire, but making the contrary can increase it.

Vassal's liberation

In AoC 2, a country can stop being a vassal if:

  • The vassal chooses the diplomatic action; "declare independence" (note that the lord will most likely declare war if this action is taken)
  • The lord liberates the vassal
  • The lord receives and accepts an ultimatum that demands the liberation of the Vassal
  • The lord liberates the vassal during peace negotiations (note that this usually only happens if the lord loses the war but can also happen in other, rare scenarios)
