Who are the most inbred royal families to ever exist? When operating under the notion of divine rule, the temptation to keep things in the family has been great historically speaking. This has its problems as you might imagine, giving rise to some of the more bizarre illnesses and maladies we associate with royals.
Ancient Egypt
One of the most inbred royal families was one of the first. The dynasties of Ancient Egypt were ruled by divine mandate. As such, it wasn’t exactly guaranteed that a commoner wife would bear the next heir.
Issues that Afflicted Pharaohs
The most intact tomb found also gives hints about the issues plaguing these royal families. Tutankhamun died at 19 but wasn’t a model of health. Tutankhamun had bone necrosis in addition to a possible clubfoot. An overbite also has helped historians tie him to to Thutmosid royal family.
Ancient China
China has a long history of fractured kingdoms. However, the concept of Heqin, or marriage alliances, has been universal throughout history. As you might imagine, this helped to create some of the most inbred royal families to exist.
Health Problems for the Emperors
The typical afflictions like the Habsburg Jaw weren’t to be seen with the emperors of China. However, many of the emperors were infertile, like Quang Tu. Try as Quang Tru might with a queen, two consorts, and a harem of thousands, there was no heir to be found.
The Silla Kingdom
Silla predates most of the famous dynasties of Korea’s past. The Joseon is perhaps the best known, but it isn’t known as one of the most inbred royal families. Silla was contemporary to nations like Rome, and it had many of the same issues.
Incest and Its Effects
Not much is written about the Silla and some of the maladies we associate with inbreeding. However, you can look at someone like Adalla of Silla, the eighth ruler of the kingdom. He had a relatively short reign and was succeeded by a completely different dynasty. Incest can lead to sterility, so it isn’t out of the question for Adalla.
Rome
Rome’s time as an empire spawned a few of the most inbred royal families you’ll find. Roman rulers did hop on the divine mandate bandwagon after a time, with certain emperors claiming to be the mortal vessels of gods.
Rare, but Possible
Incest was common throughout the ancient kingdoms of the world. However, it is a bit of a rarity in Ancient Rome. We would most likely see further evidence of things like madness. Rumors persist about infamous rulers like Nero and Caligula, but nothing concrete has been established.
Victorian England
One of the most iconic royal families is oddly one of the most stricken by incest’s effects. Ironically, Queen Victoria’s attempt to intermarry the families of Europe with cousins and siblings ended up creating many issues.
Keeping Hold of the Crown
Victoria and Albert may have likely spread hemophilia throughout all of Europe. Thankfully, no English monarchs seemed to have been born with the affliction. However, Victorian England was one of the most inbred royal families you’ll find. Victoria’s granddaughter suffered from terrible headaches her entire life, and fertility issues plagued her childbearing years.
The Kingdom of Bavaria
Long before Germany’s unification, it was home to some of the most inbred royal families in all of Europe. This likely comes down to its relation to the famous Habsburg dynasty found in the Austro-Hungarian Empire. However, it didn’t do Bavaria any favors.
An Uncomfortably Close Family Tree
King Ludwig II’s time on the Bavarian throne was short, perhaps to the benefit of his subjects. That said, he seemed to be stunted mentally. While he was a great patron of the arts, he was unfit to be king. Sadly, this led to his assassination before his equally inbred brother Otto took the throne.
Kingdom of Hawaii
When you live by divine rule, it starts to muddy the waters. While Hawaiian rulers believed that a brother and sister marrying created a truly divine offspring, modern science refutes that. It ended up creating one of the most inbred royal families you’ll ever see.
Maintaining Rule
Things went swimmingly for the incestuous relationships of Hawaii’s monarchs until the arrival of missionaries in the 19th century. There Nahienaena married her brother, King Kamehameha III, much to the consternation and condemnation of the missionaries. Sadly, it came to a head when Nahienaena gave birth to her child. Genetic defects from centuries of inbreeding led to the child’s early death.
The Romanovs
One of the most inbred royal families saw its twilight in the 20th century. The Romanovs were the ruling dynasty of the Russian Empire for centuries. The final Czar and his family suffered from several genetic defects.
Hemophilia and Other Issues
The most notable issue suffered by the Russian Royal Family was hemophilia. Nicholas II’s sole heir, Alexei, is famous for his affliction. Sadly, effective treatment wasn’t found before the October Revolution.
The Habsburg Dynasty
Rounding out our list of the most inbred royal families is the only one with a genetic defect named for it. The incestuous Habsburg Dynasty ruled over much of Central Europe as well as the Iberian peninsula.
Kings Unfit to Rule
Toward the end of the Habsburg Dynasty, rulers were heavily afflicted with genetic defects. King Charles II of Spain was one such ruler and could barely speak. The poor mad king couldn’t even chew on his own.
