直辖领法律

Demesne laws are de facto laws, defining the relationship between a ruler and their vassals. When the Conclave DLC is active, they are replaced by realm laws.

The obligations section (without Conclave activated)

Laws are graded from low to high e.g. the higher the taxes, the lower the vassals's opinion will be.

Note that levies here refer to maximum levies - the amount of their levies that a vassal with an opinion of +100 would provide. Crown laws handle minimum levies.

Highest level requires the Legalism technology:

• Harsh Tax laws require Legalism VI
• Maximum levy laws require Legalism VII

中央集權

A centralized state is important for the liege to grow powerful, but a decentralized state might be easier to maintain (or necessary, if the liege has many direct vassals). If the Conclave DLC is activated, this law is found under the Realm laws tab. Dukes and above can enact centralization laws.

Law	Vassal limit	Demesne size	Requirements	ID
Decentralized	+10	-	-	centralization_0
Low Centralization	+5	+1	Legalism I Low Tribal Organization or higher (for tribal rulers)	centralization_1
Medium Centralization	-	+2	Legalism II Medium Tribal Organization or higher (for tribal rulers)	centralization_2
High Centralization	-5	+3	Legalism III High Tribal Organization or higher (for tribal rulers)	centralization_3
Centralized	-10	+4	Legalism V Absolute Tribal Organization or higher (for tribal rulers)	centralization_4

部落組織度

Tribal organization applies to independent tribal rulers of duke tier and above. It replaces crown laws (without Conclave) or subsumes council laws (with Conclave). It can only be changed one increment at a time, but unlike crown law a ruler may change it more than once in their lifetime.

Law	Unreformed pagan vassal opinion	Effects	Without Conclave	With Conclave	ID
Minimum Tribal Organization	+5				tribal_organization_0
Low Tribal Organization	-5		Title revocation allowed	The council now votes on wars and laws	tribal_organization_1
Medium Tribal Organization	-10		Free revocation from infidels and heretics	The council now votes on grants and revocation	tribal_organization_2
High Tribal Organization	-20	Tribal vassals provide levies and taxes Tribal vassals can no longer called to war	Can set tax & levy rates	The council now votes on imprisonment, exile, and execution	tribal_organization_3
Absolute Tribal Organization	-30	Can adopt feudalism Can found a merchant republic			tribal_organization_4

Viceroyalty

With the Charlemagne DLC, independent feudal emperors can grant kingdoms or duchies to vassals as Viceroyalties. Unlike regular titles, viceroyal titles automatically revert to the liege upon their holder's death, lessening the chance that vassals will grow too powerful or pass their titles on to disloyal heirs. If the Conclave DLC is activated, this law is found under the Realm laws tab.

Note that having viceroy vassals will upset your feudal duke+ vassals who are not themselves viceroys. The opinion penalty is -2 for each viceroy kingdom and -1 for each viceroy duchy held by a direct vassal. This may make it difficult to manage a realm with both hereditary kings and viceroy kings.

Law	Vassal limit	Privileges	Requirements	ID
No Viceroyalties				vice_royalty_0
Kingdom Viceroyalties	-5	Allows nominating Viceroys	Legalism IV	vice_royalty_1
Duchy Viceroyalties	-10	Allows nominating Minor Viceroys	Legalism VIII (or automatic with Imperial Administration)	vice_royalty_2

Administration

Applies to independent feudal emperors. The Byzantine Empire starts with Imperial Administration, while other realms will only be able to adopt it later in the game.

Law	Vassal limit	Feudal opinion	Privileges	Requirements	ID
Feudal Administration	-	-	-	-	feudal_administration
Imperial Administration	+25	-10	Enables Duchy Viceroyalties law Free revocation of viceroyal duchies Free revocation of duchies (without Charlemagne) Free retraction of vassals, even from kings	Absolute crown authority Majesty V.	imperial_administration

Note that if the player is an emperor and don't see an option within Demesne Laws / Realm Laws to choose between "Feudal Administration" and "Imperial Administration", they may need to scroll down to see those options.

Note that Imperial Administration automatically gains ability to have kingdom and duchy viceroys, regardless of legalism.

Changing demesne laws

Rulers can seek approval to change a demesne law every 5 years. All vassals get a vote, weighted depending on their titles. Muslims change laws using piety instead and do not need voter support.
