[Hemophilia - a royal disease].

Haemophilia was an important contributing factor in the fall of the Romanov dynasty, thereby affecting the history of the Russian Empire as well as the history of the world at large. The occurrence of haemophilia in the reigning houses of England, Germany and Spain also influenced the course of events in these countries. The extent which haemophilia affected the history of mankind therefore gives this affliction a prominence not equalled by any other disease.
