Feud
At the Holy Roman Empire's Reichstag at Worms in 1495 the right of waging feuds was abolished. The Imperial Reform proclaimed an "eternal public peace" (Ewiger Landfriede) to put an end to the abounding feuds and the anarchy of the robber barons and it defined a new standing imperial army to enforce that peace. However, it took a few more decades until the new regulation was universally accepted. In 1506, for example, knight Jan Kopidlansky killed somebody in Prague and the Town Councillors sentenced him to death and had him executed. Brother Jiri Kopidlansky revenged himself by continuing atrocities.
