Haemophilia Haemophilia is a disorder which can be identified by the body’s inability to control blood clotting, which leads to frequent haemorrhages, whenever there is a wound. This disorder has come to be known as the “royal disease” given that the most famous case of a female carrier of haemophilia was Queen Victoria of England. Queen Victoria had one haemophiliac son and two carrier daughters. These offspring, after their marriages, transmitted the disorder to various European royals, amongst which is the Spanish royal family.
