{{version|3.0}}

'''Divine marriage''' is a feature of some religions that allows and encourages characters to [[marry]] close relatives [[File:Dynasty close relative.png]].

Initially, two religions feature divine marriage: [[Zoroastrianism]] [[File:Zoroastrian.png|24px|alt=|link=]] and Messalianism [[File:Nestorian_Heresy.png|24px|alt=|link=]] (a heresy of [[Christianity#Nestorian|Nestorian]] Christianity). It is also available as a {{icon|hf}} [[Pagans#Doctrine|doctrine]] choice when reforming a Pagan religion.

== Benefits of divine marriage ==
At the moment of a divine marriage, the ruler gains Piety: 50 for Counts, 100 for Dukes, 200 for Kings and 300 for Emperors. A similar amount of either Prestige or Gold is earned.

Some permanent [[opinion]] modifiers apply:

==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
