  • Almost all of Europe’s royal families are related.
  • These families share a common ancestor: King George II, who was the King of Great Britain and Ireland from 1727 until 1760.
  • Here is how the royal families of Spain, Monaco, the UK, the Netherlands, Sweden, and more are related.

The royal families of Europe are vast and diverse, with each family possessing different titles and powers.

But one thing they do have in common is a shared ancestor.

While the family trees are complicated, and there are many ways that Europe’s royals are all related to each other, one of the simplest is to look at King George II, who was the King of Great Britain and Ireland from 1727 until 1760.

George’s ancestors now head Europe’s royal families, as his children and grandchildren married royals from around the continent.

This means that royals in Britain, the Netherlands, Luxembourg, Sweden, Norway, Denmark, Spain, and Monaco are all distantly related to each other.

Here is an interactive family tree of Europe’s royal families. Each generation is represented by a small circle, each color represents a different family, a solid line represents a blood relation, and a broken line shows a marriage.
