{{version|3.0}}

'''血亲圣婚''' 是某些宗教的特色， 允许并鼓励角色跟近亲[[marry|结婚]][[File:Dynasty close relative.png]]

最初有两个宗教允许血亲圣婚： 
[[Zoroastrianism|琐罗亚斯德教]] [[File:Zoroastrian.png|24px|alt=|link=]]和祷告派 [[File:Nestorian_Heresy.png|24px|alt=|link=]] ([[Christianity#Nestorian|聂斯脫里派]]的异端)

同时也可以在改革原始宗教时作为{{icon|hf}}[[Pagans#Doctrine|教义]]而被选择。

== 血亲圣婚的好处 ==
血亲圣婚时，统治者会获得虔诚：一般的是50、公爵是100，国王是200、皇帝是300，并可以赚取类似数量的威望或金钱。

并会有一些永久性[[opinion|好感]]修正：

==Strategies==
=== Positive genetic traits ===
If using [[Ruler Designer]], consider giving your starting ruler the positive genetic traits {{iconify|Genius}} or {{iconify|Quick}}, {{iconify|Strong}} and {{iconify|Attractive}}. This does not reduce the risk of {{iconify|Inbred}}, but does improve the pool of potential spouses for your heir.

=== Mitigating the risk of inbreeding ===
Zoroastrians who choose to partake in divine marriages are at high risk of [[inbreeding]]. The risk of your dynasty dying out due to bad congenital traits (characters being inapt to rule, having fewer children and dying younger) is quite serious after a few generations. To prevent this you may:
* Prefer half-siblings (0.25) to full siblings (0.5) or offspring (0.5)
* Take [[concubines]] to produce heirs with more genetic diversity
* Marry dynasty members past child-bearing age
* Land dynasty members frequently to increase the pool of characters you can marry in the long term (unlanded characters are limited on number of children)
* [[Heir#Selecting_your_heir|Skip inept heirs]], e.g. using [[feudal elective]] succession
