Marrying to form alliances is a powerful option at your disposal in Crusader Kings 3. It can let you control territories you’re interested in without having to go to war. Similar to Crusader Kings II, having a powerful ally in your backpocket goes a long way. There are some really powerful people in the game whom you can take advantage of. Aside from bolstering your military power, you’ll also need an heir which can’t be done without marriage. In this guide, we’ll walk you through everything you need to know about how marriage works in Crusader Kings 3 and forming alliances through them.

Crusader Kings 3 Marriage – How to Get Married

When it comes to marrying in Crusader Kings 3, there are a couple of ways to do so i.e. ‘Find Spouse’ and ‘Arranged Marriage’. Regardless of what you choose, not every nation will accept your proposals so set your expectations accordingly. Before we talk about creating alliances, let’s briefly go through these options:

  • Find Spouse – Choosing this option will display a complete list of possible candidates from all around the world.
  • Arranged Marriage – This option will show you suitors from your own court including family members, knights, lovers, courtiers, guests, etc.

To start and see which characters you can form alliances with, click the picture of the character you wish to find a spouse for and then either click ‘Arranged Marriage’ or ‘Find Spouse’. This will show you a complete list of potential suitors whom you can form alliances with. If you’re interested in someone not listed, you’re sadly out of luck.

It’s important to remember that people who are above everyone else in the line of succession e.g. children and grandchildren make the most valuable suitors. After them comes family members like cousins, nephews, nieces, etc. Another important thing is to accept the fact that it gradually becomes difficult to form new alliances if you already have a whole lot of them. But even then, don’t let this prevent you from forming multiple alliances.

Also, since traits can pass onto children, it’s important to double-check things like traits, personality types, lifestyles, skills, etc. You should try to make use of a filter that will let you choose these things.

Allies and War

First of all, it’s important to note that waging war on an ally will add -25 Popular Opinion for 3 years. As for war against someone else, each of your allies must accept the ‘Offer to Join War’. There’s another interaction called ‘Call to War’ which your allies can accept or reject depending on different things e.g. their opinion of you, etc.
