本指南描述了通过婚姻增加家族权力的策略。这些技巧可以用于取代所有皇家血统，让家族成员登上所有王座。
这对我有什么好处?
让你的家族持有很多头衔有巨大的好处：
- 头衔的未来整合：采用年长者继承法或任何选举继承法，你的继承人可能已经有头衔。如果你最年迈，你可能继承采用年长者继承法的头衔。如果你代表家族的年长一脉，你可能会继承衰落甚至绝嗣的年幼支脉。
- 启用均分继承法，适当规划仍然可以确保继承时不会失去头衔。你自己没有子女，一位家族内继承人将继承你所有的头衔。
- 更容易接受婚姻。家族成员间结婚，你和AI都不需要关心婚姻是否入赘。
- 更容易结盟：家族成员更愿意成立互不侵犯条约和同盟。
- 不需要授予宣称者领地：为家族成员索取宣称后，他们总会成为你的封臣，所以你不需要放弃宝贵的直辖头衔。这使得你更有效地宣称女亲戚的头衔，只要头衔不是男性继承。
- 保证选举君主制下的安全，在你使得这些王国成为你的帝国法理一部分后。
- 家族威望，给予你的子女初始威望。它也直接有助于接受婚姻和枢机选举。
- 更多控制教宗和骑士团（启用
亚伯拉罕之裔）的机会。你的家族每控制一个将给予你（和其他同家族伯爵+统治者）+2每月威望和+1每月虔诚。雇佣骑士团将更便宜。 - 内阁（启用
御前会议）中的效忠者，在大多数议题上，即使没有人情也会投票支持你。 - 更高好感（+5 同一家族，每有一本关于自己家族的书将有更多好感加成）
拥有庞大家族也有一些潜在缺点：
弑亲者：你将有更少的安全谋杀的选择，并且你的继承人更可能决定杀死同家族的某人。
近亲繁殖：你可能会小心避免近亲结婚，但AI统治者不会。
腐化：如果家族成员是你的封臣，而且你的领地是家族之中最大的，那么庞大的穆斯林家族就有腐化的风险。更重要的是，家族发动的失败圣战将导致腐化激增。- 家族继承（选举均分继承法，凯尔特选任法，长老选举制或年长者继承法）可能更难预测和控制。
- 选举君主制下，家族内封臣相比家族外封臣对你的好感更低。家族内封臣也可以创建派系以要求采用均分继承法。
避免获得头衔
虽然是可选的，但是在自己保持伯爵或公爵头衔的同时“玩婚姻游戏”可以很有趣。
你需要不必太多微操就可以统治，同时也不太可能被入侵的地方。像冰岛这样的偏远地区相对来说比较安全，不会受到入侵，但却让许多统治者处于外交范围外。一个强大王国或帝国的附庸公爵可能更好。
选举君主制对于这种玩法来说几乎是必须的，原因如下。首先也是最重要的是，如果你决定的继承人去世而且/或者把他自己逼到l不适任的地步（弑亲者，专断等等），你也不是完全不走运。第二，你可能需要避开一些遗产。这种玩法不要试图继承法国，而是要保持法国的自治以及是你的血统在统治着它。最后，你可以选择一位女性继承人以利用勾引和入赘选项。
儿童
显然，为了让你的血统遍布世界，你必须有多个的孩子。
生育能力
选择高生育能力的配偶：
，
，
或高外交/管理教育特质。你也可以使用角色设计器来让你的第一位统治者有这些特质以及/或者额外的基础生育能力。
勾引生活重心让你想要多少孩子就有多少孩子。在45岁之前，女性每年可以生育一个孩子，她们可以尝试隐瞒自己的风流韵事，也可以希望统治者/继承人承认孩子是自己的。男性可以养育多位私生子。

Marriage
Now you have a brood of children, maybe with high intrigue or maybe with high fertility, ready to go out into the world and propagate your bloodline - these are specific strategies to get as advantageous a marriage as possible.
Males
By far the simplest way to get your dynasty going somewhere else is to simply regular marry your sons to landed women. Their children will be of your dynasty and the requirements for this are ridiculously low, if you are king-level or above then basically the sons which are heir and pretender (first 3) will be able to marry just about any landed woman and this can easily be done just via the normal marriage rings.
Considerations
Your married male family members are by far the largest threat to your continued autonomy as if you marry your son to a Queen, she may suddenly decide she wants your land and presses his claim. Though this wouldn't end your game, it would certainly put a large damper on it. To that end, try to make sure that you are on good terms and/or they are unable to press or too far away to consider it. This should definitely not override potentially great opportunities, though; it is simply a consideration.
Females
Females are somewhat trickier as you can't simply marry them off; you need a matrilineal marriage and those are extremely difficult to do. Sometimes, you can get a matrilineal marriage that the AI will actually accept, but more often than not, you have to pull some tricks out. Here are some strategies specific to getting these marriages.
Matrilineal marriages
AI will only consider matrilineal marriages/betrothals if the woman/girl is your sister, daughter or granddaughter. For other women/girls in your court, you must invite heirs and have the marriage take place in your own court.
AI will usually accept matrilineal marriages as long as the man/boy is not in the top three for succession to the requestee's primary title. Thus, look for men and boys who are:
- Not in the court of their parent
- Junior heirs under gavelkind or elective gavelkind
- Heirs of heirs
- Younger children of rulers, if you can murder their older brothers
- Likely to win elections in the future, but currently not among the top 3 candidates
Considerations
Again, don't let Matrilineal marriages get in the way of marrying or betrothing your daughter to a really choice Heir. Sooner or later she'll have kids and you can start marrying cousins. In the meantime it's easier to make non-aggression pacts and alliances.
Heir
A very basic method to actually getting a matrilineal marriage that the AI will legitimately agree to is by using your Feudal Elective government to elect your daughter heir. You may of course use it to elect your niece/cousin/other heir, but the AI will not even recognize that they matter so it's your daughter or nothing. This makes it so when you open the marriage screen it's automatically matrilineal. Be warned though that this has very slim pickings regardless of how powerful you are or how great she is. You may however get lucky so it's worth looking at least.
The Meat
The meat of this strategy is fairly simple: find heirs that have claims and/or extreme daddy issues and invite them to your court. Once there, they cannot refuse a matrilineal marriage and you also have the added bonus of having them in your court so that you can protect them until they inherit. Be warned, however, that if they are extreme foreigners and/or unlikable, someone in your court will probably randomly decide to kill them and practically the entire court will back them, so you must be vigilant.
How to find these is fairly simple - when you go to your daughter's character screen you attempt to regular marry her, or at least open that screen. Sort by rank (crown) and scroll down past the landed guys and right below them will be princes. Hover over them to see if any of them are the heirs to the kingdom and if so take a look if they might be a possible option. Don't discount the guys below the princes as they may not have a minor title but be heirs to a large duchy. This is the easiest way, for the more complete way (these are only the ones that are willing to marry you which may not be half of them) you go to character finder (ruler:no, male:yes, married:no, greathouse:yes) and sort by rank, all the unlanded princes will be at the top underneath mayors/bishops.
To be willing to come to your court, they either need to absolutely hate their father, which is not unusual given the AI's seeming preference for bad ruling traits, or already have a claim which means they were alive and a pretender when the previous monarch before their father died.
It is actually relatively easy to get these guys as the combination of having a title claim and how much the AI loves to give itself arbitrary/cruel/etc, there is probably more than a 50% chance that any given unlanded heir will like you better, assuming you are a likable ruler yourself.
With the Conclave DLC, favors can be used to force an invite to your court, subject to some restrictions. This is the only way to invite claimants of other religions.
Remarriage
Whenever you marry off your children/eligible kin to someone with the intention of spreading your bloodline, mark their spouse as a 
person of special interest (right click -> star on the left). This will notify you if they die so that you can retrieve your guided dynasty missile for reuse somewhere else. If they are male and the heir and/or regent then definitely just leave them there for now and check up on them when their child grows up, if they are female definitely do everything in your power to get them back as there is only a certain window where they can have children.
Courtiers
You don't have to worry about marrying courtiers, but sometimes a Matrilineal marriage is just an easy way to get rid of somebody with a low opinion of you without going to the trouble of a plot. Again, it's good for getting hold of claims or boosting borderline opinions or making non-aggression pacts, as arranging marriages that benefit the courtier (ie giving them land) will make them a bit happier.
Don't worry too much about betrothing the children of courtiers, as they can't leave your court until they're adults anyway, and you can deal with them then.
Female matrilineal courtiers are basically bargaining chips to get the right people to come to court, without having to use your own bloodline to do it.
Muslim Rulers
As Muslim Iqta rulers, you are largely limited to Open succession, and only until late game law changes will you be able to have matrilineal marriage. However the unique inheritance also benefits you in that you will not lose any titles as Open Succession means that the most powerful son inherits all the titles, this also gives you great flexibility in determining your heir. If you do not have any legitimate sons then your most powerful brothers will inherit. If none of your sons have titles then it defaults into agnatic primogeniture, which is fine for you.
After finding your ideal heir you need to look at how you can gain claims to titles that you so desire(and since women can't inherit until late game you will need to fight to seize these titles). Use the guide above to find female young fertile claimants with inheritable claims or look at titles in de jure page and find them. Marry them to your son. Invite as many as possible to your court and then land your son and heir. After that you can marry more female claimants to your son since he is Muslim and landed and thus get to have four wives(along with all their wonderful titles).
After which you would die and become your heir, then your oldest son/heir would inherit your titles and claims. Declare war when convenient and if done correctly, your son and heir would hold the duchy/kingdom and when you die, your realm will be sufficiently enlarged!
Conclusion
Don't despair if your carefully crafted bloodline replacement goes awry. A significant percentage of the time, some random bishop will methodically murder every one of the heirs that would have been of your dynasty and there is nothing you can do about it, really.
However, if it takes and you get past the first generation, then all of a sudden their interests are your interests, namely keeping your dynasty in power. Do what you can to help them out like putting down the inevitable rebellions and especially keep an eye out for usurpers. In addition, since the ruling dynasty is yours, if somehow the entire royal family dies out (mysteriously) then it will now look at your dynasty for possible inheritors.
Once you get to the 2nd generation, you are more or less free to worry about your other "colonies" as the bloodline is mostly established. Feel free to invite your own bloodline over to you like you did their grandfathers to make sure they get decent marriages and/or intermingle the royal families so that if they do lose the royal family, they will search others of your dynasty.
