Haemophilia in European royalty

Haemophilia in European royalty has played a significant role in the history of 19th and 20th-century monarchies, largely due to the inheritance of the disease from Queen Victoria of the United Kingdom. The genetic mutation causing haemophilia was passed on through Queen Victoria's daughters, Princess Alice and Princess Beatrice, spreading the condition to various royal houses across Europe, including Spain, Germany, and Russia. Queen Victoria's youngest son, Prince Leopold, Duke of Albany, also suffered from the disease, while her three elder sons did not. This occurrence of haemophilia in the European royal families led to the condition's former nickname, "the royal disease."

Understanding Haemophilia

Haemophilia is a group of hereditary genetic disorders that impair the body's ability to form blood clots, a process needed to stop bleeding. Two of the most common forms of haemophilia are haemophilia A (factor VIII deficiency) and haemophilia B (factor IX deficiency). The type of haemophilia associated with European royalty is the relatively rare haemophilia B.

Transmission in Royal Families

Queen Victoria is believed to have been a carrier of haemophilia B and passed it on to her descendants, which had significant implications for European history. This included the royal families of:

• Spain: Victoria's granddaughter, Princess Victoria Eugenie of Battenberg, married King Alfonso XIII of Spain. Their sons Alfonso and Gonzalo were affected by the disease.
• Germany: Victoria's granddaughter, Princess Victoria of Hesse and by Rhine, passed the haemophilia gene to her son, Prince Friedrich of Hesse and by Rhine, who died from a brain haemorrhage after a fall.
• Russia: The most famous case is that of Tsarevich Alexei, son of Tsar Nicholas II and Tsarina Alexandra (a granddaughter of Queen Victoria). His severe haemophilia was a factor in the fall of the Russian monarchy.

Impact on European History

The presence of haemophilia in European royal families had a significant impact on the politics and historical events of the time. For instance, the condition of Tsarevich Alexei influenced the royal family's relationship with Rasputin, which played a part in the Russian Revolution.
