Queen Victoria of Britain, whose descendants have been kings and queens of several countries in Europe, carried the gene for hemophilia, which has turned up repeatedly in royal families since her lifetime. Her great-grandson, the heir to the throne of Russia, suffered from the disease, and his parents fell under the influence of the monk Grigori Rasputin in hopes of a miraculous cure. The resulting chaos in the government of Russia helped bring on the Russian Revolution and the establishment of the Soviet Union.

Etymology

Origin of hemophilia

From New Latin, dating back to 1850–55; see origin at hemo-, -philia

Explanation

Hemophilia is a genetic disorder that makes it hard for a person's blood to clot. People with hemophilia are at risk of bleeding a lot even from minor injuries. The medical term hemophilia comes from the German hämophile, from Greek roots haima, "blood or streams of blood," and philia, which means "to love" but can also have the sense of "tendency to." The earliest recorded case of hemophilia was in the 10th century, but the disorder wasn't understood until the 1800s. Men are much more likely than women to suffer from hemophilia.
