Haemophilia figured prominently in the history of European royalty. Queen Victoria passed the mutation to her son Leopold and, through several of her daughters, to various royals across the continent, including the royal families of Spain, Germany and Russia. For this reason it was once popularly called "the royal disease".

Victoria appears to have been a de novo mutation, as her mother, Victoria, was not known to have a family history of the disease. Queen Victoria's father, Edward, was not haemophiliac, and the probability of her mother having had a lover who suffered from haemophilia is minuscule as, in the Nineteenth Century, male haemophiliacs tended to die before they could sire children. Descendants of Victoria's maternal half-sister, Feodora, are not known to have suffered from the disease.

The disease passed on to

It is unknown if Victoria's third or fourth daughters, Helena or Louise were carriers. Louise died without giving birth to any children. Helena had two healthy sons, but also two younger sons who died in early infancy and two daughters who both died childless, so there may have been a possibility that either of the younger sons could have been sufferers or the daughters could have been carriers.

In popular culture

"Tooth and Claw", a Doctor Who story set in Scotland of 1879, mentions "the Royal Disease" at the dénouement of the episode. It suggests that a werewolf bite that Queen Victoria received, rather than a de novo mutation, is responsible for the disorder. (The story ignores the fact that Victoria's son Leopold was born in 1853, and suffered from the disease all through childhood.)th:โรคเฮโมฟีเลียในราชวงศ์ยุโรป
