Demesne

Alert demesne.png A demesne is a character's collection of personal holdings. Such holdings may either be counties or baronies. A ruler's capital is an important part of their demesne.

A character's demesne (pronounced /dɪ'meɪn/, almost but not quite like "domain") will usually provide the majority of their income, as well as a decent amount of levies (both from land personally held and from vassal barons). It is within one's demesne that most construction occurs, including construction of new settlements in county empty slots.

Each ruler (except nomads) has a demesne limit, and exceeding it causes a penalty to taxes and levies. This limit is what forces rulers to distribute power to vassals rather than directly controlling their entire realm. A ruler's demesne limit is based on tier, personal and spouse stewardship, succession type, and centralization law.

Icon demesne.png Demesne limit[edit]

Nomadic rulers do not have a demesne limit. Instead, Khagans will be increasingly pressured to give out excess nomadic counties (defined as counties with 0 or 1 settlement) to vassal clans (or to start a new clan), as excess counties lower clan sentiment, which lowers vassal khans' opinion towards the Khagan. If the Khagan continues to hold onto too many counties, a minor clan can rise up in rebellion to force the Khagan to recognise it as a major clan. The Clans screen will indicate whether a Khagan needs to give out nomadic counties. However, while nomads are in control of holdings to carry out pillages, their liege tax is reduced until the pillages have destroyed the holdings.

When a ruler is over their demesne limit, they suffer penalties due to inefficiency:

  • Reduced opinion from vassals (-10 per settlement over limit)
  • Reduced demesne levies, except in the capital (-20% per, up to -90% with the 5th)
  • Reduced demesne income (-20% per, up to -90% with the 5th)
  • Reduced tax from vassals (-20% per, up to -100% at 5 over)

There is a 2-month grace period when a ruler goes over their limit due to acquiring new titles. However, if a ruler goes over their limit due to a reduction in stewardship skill, the penalties kick in immediately.

The demesne limit is (the   notation refers to rounding   down to the nearest integer):

 

Gavelkind[edit]

Gavelkind Bonus = 1.3 (+30%) if you are under Gavelkind or Elective gavelkind succession law, 1 otherwise.

Rank[edit]

Each rank has a base demesne value:

Rank Base demesne Notes
Baron/Count/Duke 1
Great Duke 2 A "Great Duke" is a Duke with 2 or more duchy titles.
King 3
Emperor 4

Unlike feudal lords, Patricians have different base demesne sizes. The base is 2 for a patrician and 3 for a doge, no matter what rank title they hold.

Stewardship[edit]

The stewardship bonus is (in case of polygamy, only the primary spouse's stewardship is used):

 

Here is a table of the   values required to achieve a certain increase in demesne limit relative to the limit you would have without Gavelkind and with 0 stewardship (note that this is different from the stewardship bonus, since the actual stewardship bonus is multiplied by 1.3 in the case of Gavelkind):

Succession Rank +1 +2 +3 +4 +5 +6 +7 +8 +9 +10 +11 +12 +13 +14 +15 +16
Not Gavelkind any 7 14 20 27 34 40 47 54 60 67 74 80 87 94 100 107
Gavelkind Duke 4 9 14 19 25 30 35 40 45 50 55 60 66 71 76 81
Gavelkind Great Duke 3 8 13 18 23 28 33 38 44 49 54 59 64 69 74 79
Gavelkind King 1 6 11 16 22 27 32 37 42 47 52 57 63 68 73 78
Gavelkind Emperor 0 5 10 15 20 25 30 35 40 46 51 56 61 66 71 76

This table can be computed using  

Tribal[edit]

Tribal rulers get a +2 bonus to their demesne, at a cost of -10 to their vassal limit.

Law bonuses[edit]

Centralization Bonus depends on the Centralization law, available to dukes and above:

Level Decentralized Low Centralization Medium Centralization High Centralization Centralized
Bonus +0 +1 +2 +3 +4

With the  Conclave DLC, absolutism (all council laws in ruler's favor) gives +2 demesne size.

Breakdown[edit]

The in-game tooltip breakdown may be confusing, as values are rounded as integers for display, but formula uses float values behind.

Here's an example illustrating the tooltip discrepancy for a king with 12 stewardship married to a wife with 9 stewardship under gavelkind succession:

  • Rank Base Demesne: 3*1 = 3, displayed as +3
  • Stewardship Bonus: 0.15 * (12 + 0.5*9) = 2.4, displayed as +2
  • Gavelkind: 30% * 5.4 = 1.6, displayed as +1
  • Total: 3 + 2.4 + 1.6 = 7, displayed as +7 and not +6

Wrong settlement type[edit]

Characters get a 75% penalty to income and levies in demesne settlements that do not match their government type. These settlements should generally be given to a vassal of the correct type or to a courtier (who will automatically take on the correct type).

Other considerations[edit]

  • If playing as a  Muslim Caliph or a   reformer of a pagan faith with the Temporal leadership type, consider holding a temple in one of the denomination's holy sites to increase moral authority.
  • If aiming to change religion, consider holding a county of the relevant faith's holy sites for the option of secret conversion. In particular for Abrahamic faiths, consider holding the county of Jerusalem. Another way of secret conversion is via a demesne county's religion.
  •   Holding counties which are considered important on the Silk Road can boost your income as you build and upgrade trade posts.
