A Dynasty represents an unbroken Noble line descending from the same Landed character who founded the Dynasty. Each Dynasty is made up of multiple Houses and Families working towards bringing Renown upon the Dynasty. A Dynasty can be renamed by the Dynasty Head at any point.


Each Dynasty will have a Founding House, usually of the same name as the Dynasty, which is the first House of that Dynasty. Ruling Dynasty members of Feudal or Clan Government who are distant by blood to the current House Head may choose to create a Cadet Branch, a new House under the Dynasty. Each House has its own name and motto, usually inspired by the location in which they are founded and the founding character, which can be changed at will by the House Head. They will also have a unique coat of arms that has two quarters copied from the Dynasty coat of arms.

Creating a Cadet Branch has the following requirements:

  • The character must be blood-related to their current House Head
  • The character must not stand to inherit any of their current House Head's titles
  • The character must have sufficient Prestige
  • All ancestors of the character are dead

If a House Head demands the religious conversion of a House member and the member refuses, it will result in the creation of a new Cadet Branch.

Each character born from a Marriage will belong to the father's House unless the marriage is Matrilineal.

House Head[edit]

The House Head is the leader of a House. House Heads have the power to legitimize bastards, call House members to war at no cost and demand that they convert to their Faith. In addition, House Heads will get a  Weak Hook on all newly born House members and monthly prestige from living and landed members of their house. If a faith has the Must be approved doctrine for divorces but no head of faith, the House Head must approve of divorces.

When a character creates a Cadet Branch, they become its House Head, and free from the direct influence of their old House Head unless they were the Dynasty Head.

When a House Head dies, their Primary Heir becomes the next House Head. One exception: The house head at the start of the game is determined differently. If the founder of the house is still alive, the founder will always be the house head. If the founder is not alive, then the house head at game start will be the house member with the largest realm size. This is why Ludwig II is the Karling house head in 867, even though he is not the oldest male child.

Dynasty Head[edit]

The most powerful House Head of a Dynasty (as determined by military strength) will be the Dynasty Head. If another House Head becomes 10% stronger than the current Dynasty Head, they will become the new Dynasty Head. The Dynasty Head gains Monthly Prestige from living and landed members of their Dynasty. The Dynasty Head has access to the following interactions with dynasty members of the same faith:

The interaction is not limited to Diplomatic Range but is not available if the Dynasty Head's faith has the Pacifism tenet, the Dynasty Head is at war or truce with the Byzantine Empire or the Byzantine Empire title was destroyed.

Dynasty Legacies[edit]

Dynasty Legacies are permanent modifiers and unlocks that can be unlocked by the Dynasty Head and affect every member of a Dynasty. Each Legacy contains five unlocks, and if an AI character becomes Dynasty Head it will only unlock Legacies belonging to the tree with the highest current progress. The first Dynasty Legacy costs 250  Renown to unlock and each one afterwards costs 500 more than the previous one.

  • Give titles to dynastic members: Landing Dynasty members allows them to have their own Court, allowing them to better procreate. Under partition type succession, giving titles to junior heirs reduces the number of claims they receive, reducing infighting.
  • Allow landed dynastic members to be independent of you: Dynastic members who are Vassals (direct or otherwise) of another dynasty member do not generate Renown.
  • Wed dynasty members to non-vassal rulers: Being married to a ruler generates 80% of the Renown that holding their primary title in one's own right does.
  • Interests of the Dynasty come first: Consider alliances with dynastic members, and help them with their wars, especially those which would cause them rank demotion due to the loss of their top-tiered title, or allow them to advance in rank. On the other hand, they only need one title to increase their Renown contribution.
    • With dynastic vassals, consider revoking their titles as a last resort.
    • Disgruntled dynastic vassals can be given independence (or granted to your liege as their vassal) so that they don't add power to factions. This has the added advantage of increasing Renown gain.
    • Dynastic wars should be avoided as much as possible.
