There are so many royal families in Europe. Are they related by blood?

Most royal families in Europe are related by blood, because in ancient times, they needed royal marriage and affiliation to form. Queen Victoria of England gave birth to many children, most of whom became relatives and kings of other royal families in Europe. Queen Victoria is also known as the "grandmother of Europe"

In fact, they want to keep their noble blood, so they try to keep their purity. Even intermarriage between countries will only exist between the royal family and the royal family. For example, the European royal family we see today, Queen Elizabeth II, King Carl 16 of Sweden, Queen Margrethe II of Denmark and King Juan Carlos I of Spain are all descendants of Queen Victoria.

In other words, let's take Greece for example. The father of the Greek prince is Greek, but his mother is French, his grandfather is Danish, his grandmother is Russian, and the other grandmother is descended from the Spanish royal family. Look at this complicated blood relationship, and you will know that they are all members of the royal family of their respective countries. From19th century to the beginning of 20th century, all the royal families in Europe were related. Queen Victoria has nine children, all of whom are members of the royal families of some other countries. The most interesting thing is that Kaiser Wilhelm II and Tsar Nicholas II are cousins, and they are related to Edward VII of England as an uncle. But they fought for their lives in the First World War.

But the marriage of their close relatives made their offspring suffer from a disease called hemophilia. People at that time didn't know the importance of blood relationship, so they also called hemophilia "royal disease". In short, there are so many royal families in Europe and they are related by blood.
