Academic fencing (German akademisches Fechten) or Mensur is the traditional kind of fencing practiced by some student corporations (Studentenverbindungen) in Germany, Austria, Switzerland, and to a minor extent in Flanders, Latvia, Lithuania, and Poland. It is a traditional, strictly regulated épée / rapier fight between two male members of different fraternities with sharp weapons. The German technical term Mensur (from Latin, dimension) in the 16th century referred to the specified distance between each of the fencers.
