Royalty[edit]

Europe[edit]

The royal couples listed below are but a sampling of the innumerable marriages that have occurred between cousins, of varying degrees, from royal or noble houses. Such royal intermarriages have been common, as it has generally been deemed inappropriate for royals to marry commoners.

Due to the constitutional interest that has attached to royals' marital status, as well as the fact that genealogical records for royal houses tend to be more readily available than those for commoners, their bloodlines are generally better known than those of commoners.
