| http://www.w3.org/ns/prov#value | - The European murder rate fell 35-fold from the Middle Ages to the beginning of the 20th century (check out this amazing 2003 paper from Michael Eisner, who dredged up medieval records to estimate European homicide rates in the swords-and-chivalry era, if you don???t believe me).The decline has been especially marked in recent years.
