Well, these days all the major European royal families have had major infusions of new blood, what with all the married-ins. In fact, have there even been any cousinly marriages in this generation?
I don’t think so? Not close cousins anyway. The last major royal cousin marriage I can think of offhand was QE2 and Philip who were both second cousins and third cousins. After that I think the reigning European families went for fresh blood, much better for the children. Among the non reigning families I think there’s still cousin marriage going on, certainly with Gabriella Habsburg and Henri Bourbon Parma*, who are both second and third cousins. But even amongst the children of the corn Imre had the sense, or some sort of survival instinct, to marry fresh blood.
*they married in 2020 but they had a child together first.
