Open or Turkish succession is a succession law where the most powerful descendant inherits all.
- Before Holy Fury, available only to Muslims, and is generally their only available succession law
- Muslim Merchant republics use Patrician elective like other merchant republics.
- Iqta realms can use feudal elective only after passing 'Full council authority" council law, which requires Conclave DLC. Once elective succession has been adopted, it will be kept even if the council laws are changed.
- One of the few non-gavelkind succession laws available to tribal rulers (the others being Tanistry, exclusive to Celtic cultures and holders of certain bloodlines, and Eldership).
- With , available to reformed pagans with the Agnatic Clans or Enatic Clans doctrines.
- Fratricidal succession wars may result, as most of the potential heirs may already be landed in an attempt to determine the final succession. Potential heirs also have bad relationships with the successor, due to -20 opinion from "title claimant" and -20/-40 from "brother/half-brother".
- Gender law normally restricted to agnatic . With Conclave, Notable status of women and Full status of women permit enactment of respectively agnatic-cognatic and absolute cognatic.
- All non-inheriting male children receive strong claims on all titles. All female children receive inheritable weak claims.
- Bastards can inherit, an exception to the normal rule. This results in a game over should it happen to the player, as the child will still be considered "non-dynastic".
Sons and grandsons are both equal, and have priority over other relatives. Sons of daughters are not eligible at all (if non-dynastic?). However, if the gender law is agnatic-cognatic (requires Conclave DLC and relevant level of "status of women" law), non-dynastic grandsons can inherit if their mothers are in the line of succession.
The following criteria are taken into account to select the heir:
- the number of titles
- the rank of titles (e.g. duchy > county > barony)
If no close dynastic relative is landed, then the eldest son will inherit, followed by other sons, the father (in the special case of when the title was given and not inherited from him), then brothers, then uncles. Living sons seem to be preferred over elder-branch grandsons when no descendants are landed.
In case of no dynastic heir, whoever has the most land in the realm will inherit, subject to rank restrictions (e.g. duchy > county > barony).
- Land the heir with the best traits.
- Giving him only a castle or mosque which is de jure part of your demesne counties is safest. As a baron-tier ruler, he won't get himself tangled in wars with other vassals, and he'll accept marriage proposals without the "desires a better non-aggression pact" malus. However, if The Reaper's Due is active, barons cannot appoint Court Physicians, leaving them vulnerable to disease.
- Preferably, this heir should have become decadent and accepted "straightening up", thus preventing him from being decadent again.
- Avoid landing other sons when possible to reduce succession troubles (and to prevent them from fathering lots of grandchildren who may cause even more decadence). However, sons who have become decadent and straightened up can be considered for succession.
- Control the number of potential heirs by marrying women who are 40 years old. Arrange marriages for sons (a mix of fertile and old women and hit the maximum of 4) before landing them.
- Gender Law (Requires Conclave DLC or game rules setting)
Adopting agnatic-cognatic allows matrilineal marriage, which is useful if females of your dynasty have desirable genetic traits. However, all grandsons (even non-dynastic ones) stand to inherit if their mothers (your daughters) are in the line of succession. Marrying claimants to female dynasty members matrilineally means that your dynasty stands to inherit land once the claims have been pressed.
For absolute cognatic, note that matrilineal marriages in Islam are monogamous. This, combined with female fertility ending at age 46, means that you have less heirs. However, your sons are more likely to have the -20 opinion modifier for full brothers, rather than the -40 one for half-brothers. Also, remember that female rulers can die during childbirth or be incapacitated by a Troubled Pregnancy, potentially causing a regency; the Final Months of a pregnancy will always trigger a regency for female rulers.
Since open succession combined with polygamy typically produces an unusually large number of claimants compared to conventional feudal realms, it is usually fairly easy to find a claimant for any given title whom you can invite to your court, land, and then press the claim for. You can further combine this with the favor mechanic to rapidly conquer large swathes of Muslim realms, even if you yourself are not a Muslim.
Reformed Pagan Strategies
- Unlike Muslims, reformed pagans with Open succession do not have to worry about decadence.
- If reformed pagan is a nomad, Open succession is arguably superior to Nomadic succession as all males (with Agnatic Clans) / females (with Enatic Clans) of the dynasty will be eligible to inherit. (Nomadic succession disinherits dynasts of a different culture.) If playing as a Khagan, Open succession allows children to inherit instead of losing the Khaganate to a vassal clan.
- However, as nomads cannot hand out titles to courtiers easily, they have some difficulty in determining the succession.
- Gender Law
- Due to the same reasons listed above, it is probably better to choose Agnatic Clans over Enatic Clans unless the dynasty has a heavy female presence.
