两类王权法（英文：crown laws）决定了一个国家的国王或皇帝的权力：
王权法总是适用于他们的法理国家，即使那些省份目前属于另一个国家（不同宗教时例外）。因此，如果一个省份法理上属于另一个被征服的王国，并且那个王国有一位国王，他们的王权法将适用于这个省份。如果国家的一部分法理上属于未正式建立的王国，则采用主头衔的王权法。
王权法中具体适用于封臣的方面基于封臣的首都所在地来决定。一位封臣完全有可能获得高王权导致的好感修正，即使他的大部分地产都位于一个低王权的王国。
只要国家当前没有被摄政统治，没有处于内战，或者王权法之前没有被当前统治者更改过，不是部落制国家，则王权法可以随时提议投票。
如果 
御前会议DLC激活，王权法分离成其组成部分的法律（参见领地法）；神职叙任权大体与之前一样。
王权
王权（英文：Crown Authority）决定了国王/皇帝对他们的封臣有多大权力，并且影响国家的几个方面。它是王权法并且决定了每个王国/帝国的基础。它决定了：
- 封臣义务提供的征召兵数量。此数量从封臣自治的0%开始，每级王权增加20%，最高到绝对王权的80%。该法律无视好感和征召兵法律，只要它更高。因此，更高王权意味着玩家能够在他们的封臣不喜爱他们的时候（例如，某次继承后）也能调集更多征召兵。
- 封臣为他们自己的战争能够调集的征召兵数量。Vassals must leave 20% per level of their demesne levy troops in their holdings, as if they were garrison troops. When raising levies from their vassals, however, dukes get the benefit of crown authority without suffering the opinion penalty from their counts.
- 在每一级王权增加国王的特权。
- 来自封臣的好感修正，这使得因为低好感，他们更不愿意提供税收和征召兵，更有可能加入派系。
- 封臣为降低王权而加入派系的倾向。
王权有五级，从封臣自治到绝对王权。随着王权增加，君主变得更加强大，而封臣因为失去一些特权，对他好感降低。
如果由一位公爵创建一个新王国，默认等级为限制王权。由已存在的国王或皇帝创建的其他王国获得其当前主头衔的王权等级。这使得在创建一个新王国之前，将自己的主头衔转换为拥有最高王权等级的王国是明智的行为。
增加王权时，所有该王国头衔下的法理封臣对你的好感-30，持续5年。
| 封臣好感 | 国王特权 | 继承法 | 最小征召兵 | 要求 | |
|---|---|---|---|---|---|
| 封臣自治 | +5 | 均分继承法，选举君主制 | 0% | ||
| 限制王权 | -5 | 剥夺头衔。 | 幼子继承法 | 20% | 法律化 I |
| 中等王权 | -10 | 随意剥夺异教徒和异端的头衔，封臣不能互相开战。 | 年长者继承法 | 40% | 法律化 II |
| 高王权 | -20 | 封臣头衔不能被外国人继承。 | 长子继承法 | 60% | 法律化 III |
| 绝对王权 | -30 | 封臣不能发动战争。 | 80% | 法律化 V |
无王权法
如果所属法理王国不存在（或者如果法理王国存在，但国王信仰其他宗教），独立伯爵和公爵默认没有王权法。该情况在大多数方面的功能类似封臣自治王权等级，但有两个例外：头衔可以被剥夺，并且任何继承法可以被选择。这意味着在创建一个王国前，有可能采用长子继承制（通常也是非常理想化的，因为在低王权的情况下采用是不可能的）。独立的伯爵和公爵可以皈依不同于其法理国王的宗教，以逃避法理王国（如果存在的话）的王权法。但是，如果转化为一个法理国王认为是异端或异教的宗教，法理国王可能发动圣战。
封臣自治
也称为“最低王权”，是最弱级别。没有最小征召兵。封臣头衔不能被剥夺。最高级别封臣可以使用“采用选举继承法”派系——降低王权的努力对野心勃勃的公爵有很强吸引力。
限制王权
在限制王权等级，领主被允许剥夺头衔。此能力极其重要，因为你可以从任何叛乱封臣处随意剥夺一个头衔，允许你以一种使国家更稳定的方式来重新分配权力。该级别有时也称为“ 低王权”。这是未改革原始宗教和商业共和国可以达到的最高级别。
中等王权
在中等王权，领主可以随意剥夺异端，异教徒的头衔。他们的头衔可能被重新分配给更喜欢你的封臣，而不必去处理那些巨大的好感惩罚。如果要求改信被拒绝（因为低好感，特别是 
角色），玩家宗教有低宗教权威，或者计划转变为其他宗教，这种能力十分重要。
封臣不能互相开战。这可以防止一位封臣变得过于强大，也有利于将他们的野心转向对外扩张。然而，有两个例外。封臣的封臣仍然可以反叛他们的领主（通常有派系）。如果封臣国王的主王国头衔不是帝国的法理封臣，可以无视此规则。
解锁年长者继承法。
高王权
通过高王权后，头衔不能再被任何外国角色继承，因此将不再会由于继承而失去国家的一部分。这使得继承更易预测。
Plots of sub-vassals against their lieges are disabled at this Crown Authority Level, as are plots of dukes to weaken each other. This further reduces the amount of fighting between vassals. The only remaining possible intra-vassal wars are counts attacking their lieges directly, without using a plot.
解锁长子继承法。
绝对王权
绝对王权（也称为“最高王权”）赋予最后一个特权：封臣不能发动战争（叛乱是例外）。这意味着封臣将不能再通过从国外夺取土地来变得强大，并使他们更易于管理。除非是帝国法理封臣，它不适用于任何国王封臣。

神职叙任权
Investiture laws are Crown Laws that only apply to Catholics; no other religion has them. The choice of law represents the historical conflict between the nobility and the Pope about who should appoint the local bishops. Investiture law decides if the Pope appoints bishops, or if their liege does.
教宗神职叙任权
When a kingdom or empire uses Papal Investiture, bishops will be generated randomly. With 
Sons of Abraham, rulers in good standing with the Pope can spend gold and piety to nominate a bishop.
The historical investiture controversy began in the eleventh century. After the year 1000, the Pope will have a negative opinion of kings/emperors with Free Investiture, and occasionally request that they switch to Papal Investiture. Catholic kingdoms start out using Papal Investiture, and can always switch to Free Investiture, but cannot switch back to Papal Investiture before the year 1000, unless requested by the Pope as a condition for officiating a coronation ceremony.
Emperors who have Papal Investiture can only ask the Pope to officiate their 
coronation ceremony.
If the HRE has Papal Investiture, clergy electors under the Princely elective system have increased voting power.
自主神职叙任权
If a ruler has Free Investiture, they will be able to appoint the successor to any bishopric that is their direct vassal, and every vassal within the de jure kingdom will be able to do the same. This makes vassal bishops considerably happier with their lieges, as they are grateful for having been appointed, and they will get +10 opinion with whoever their liege is. Former courtiers that was appointed will have an additional +50 opinion toward the liege. Any vassal under the liege that has bishops as their vassals will also be pleased, as they now have control over their bishops. Free investiture will also enable appointment of an antipope.
However, the Pope will be quite unhappy with this state of affairs. A ruler with free investiture has a penalty to acceptance of papal requests and is more vulnerable to hostile requests such as excommunication. Furthermore, after the year 1000, rulers with Free Investiture will get -30 opinion with the Pope and may receive a letter from the Pope demanding Papal Investiture. Rulers may choose to comply (this raises the moral authority of the Church by 2%), refuse (reduces MA by 2%), bribe the Pope (costs 200 gold), or if Learning skill of the ruler is above 16, refuse on theological grounds (gives you piety).
This means that over time, Free Investiture does have the potential to be a moderate money drain. However, as long as the realm is moderately large, the gold needed for a single Papal bribe is unlikely to be more than a couple years' income at most. The largest disadvantage to Free Investiture is the much increased risk of excommunication; as long as there are political enemies and a lack of traits which the Church likes, the player can easily end up excommunicated, giving every Catholic in the world a casus belli against them and reducing all Catholic vassals' opinion by 15.
Catholic emperors who have vassalized the Pope should consider having Free Investiture before their (and their successors') coronation by the Pope, so that the Pope can ask for a law change rather than independence (which is another valid and popular request).
Recommendations
- Unless often excommunicated, use Free Investiture for a steady increase in gold. With , emperors would want to use Free Investiture to have flexibility in choosing who to crown them, and to satisfy a papal request for Papal Investiture in exchange for coronation.
- Medium Crown Authority generally grants the best of both worlds.
- To control inheritance and loss of land, it's probably a good idea to invest in High Crown Authority.
- To change your laws to Seniority succession, Medium Crown Authority is required.
- To change your laws to Primogeniture succession, High Crown Authority is required.
- It's generally recommended to have Limited Crown Authority, unless the ruler and their heir have no reason to revoke vassal titles.
- If independent and a duke or count, and the de jure kingdom exists, consider converting to a religion that has "religious differences" to the de jure king's religion. Succession laws can then be controlled and will not draw the de jure king's attention by being a heretic or infidel.
单一王国的多重王权法
It is possible that a Kingdom title does not get a set of crown laws of its own, but automatically receives those of its liege's title. This is displayed in the laws screen with the message in the format "The Crown Laws of <empire> apply in <kingdom>" where the law buttons would usually be.
If the kingdom is both a de facto and de jure vassal of its liege, its crown laws are the same as its de jure liege. Otherwise, the kingdom has and sets its own crown laws.
Some examples:
- The King of Italy is a vassal of the Holy Roman Emperor. The Kingdom of Italy has and sets its own crown laws, because the HRE is not its de jure liege.
- The King of Bavaria is a vassal of the Holy Roman Emperor. The Kingdom of Bavaria uses the same crown laws as the HRE, because the HRE is its de jure and de facto liege.
- The King of Frisia is independent and the HRE exists. The Kingdom of Frisia has and sets its own crown laws, because the holder has no de facto liege.
- The Holy Roman Emperor is also the King of Germany. The Kingdom of Germany has and sets its own crown laws, because the holder has no de facto liege.
- The King of France is also the King of Aquitaine. Both the Kingdom of France and the Kingdom of Aquitaine have and set their own crown laws, because the holder has no de facto liege.
在两个或多个王国的王权法适用情况
A kingdom or empire's de jure territory is often held by different independent realms. Which crown law applies to a particular county at any given time can be seen by using the de jure kingdom or de jure empire mapmodes and mousing over the county in question.
These are the rules for which crown law applies in a county in order of highest to lowest priority:
- The de jure kingdom's crown laws inside its de facto realm.
- The de jure empire's crown laws inside its de facto realm.
- The de facto top liege's crown laws if the de jure liege title is held by a character of a different religion.
- The de facto top liege's primary title's crown laws if no de jure liege title exists.
- The de jure kingdom's crown laws in the realm of an independent duke or count.
- No crown laws apply, if its de jure kingdom and empire do not exist and its top liege is a duke or count.
Some examples:
- The king of France holds the county of Paris. The crown laws of France apply.
- The Holy Roman Emperor holds the county of Köln. The crown laws of the HRE apply.
- The Catholic Holy Roman Emperor holds the county of Paris and the king of France is Catholic. The crown laws of France apply.
- The Catholic king of France holds the county of Köln and the Holy Roman Emperor is Catholic. The crown laws of the HRE apply.
- The Sunni sultan of Andalusia holds the county of Paris and the king of France is Catholic. The crown laws of Andalusia apply.
- The Sunni sultan of Andalusia holds the county of Köln and there is no king of Germany nor a Holy Roman Emperor. The crown laws of Andalusia apply.
- The independent duke of Valois holds the county of Paris and there is a king of France. The crown laws of France apply.
- The independent duke of Köln holds the county of Köln and there is no king of Germany nor a Holy Roman Emperor. No crown laws apply.
