1. All In The Family

Inbreeding was a common practice among ancient royals. This is an obvious taboo today. But, before people knew the scientific ramifications, it was seen as a way to keep and consolidate power within a ruling family. For example, Cleopatra had only two great-great-grandparents. The average person has sixteen!

Ptolemy V and Cleopatra I were her great-grandparents but were related to literally everyone else in her family tree. Gross, we know. Although not considered “beautiful,” Cleopatra isn’t recorded to have any traits characteristic of inbreeding. Nowadays, royal families avoid this practice for obvious reasons. However, many royals in different countries are still distantly related because of this practice.
