NOTE: This page covers the basics of using the Arrange Betrothal button in the diplomacy pane. For more information on Betrothals, visit the other Betrothal topic.
The Arrange Betrothal button in the Diplomacy pane functions almost exactly like the Arrange Marriage button does. The difference is that when you view the ‘Select a Spouse’ list the first time, the available courtiers will now include children. If you select an adult from the first list, then you will only see children in the second, because if both parties were adults, it would be a marriage and not a betrothal.
