June 16 is the big battle day in AFM Oerlinghausen. This is exactly what it sounds like: fighting. The history of humanity is characterized by physical conflicts. On battle day, visitors start a journey through the history of the duel. Which weapons did the first humans fight with? And better asked why? Among other things, the Hamburg group Ludus Nemesis brings Roman Gladiature on this day and reflects on what fascinated the audience at such a blood spectacle at that time so much. The Bielefeld club Drey Wunder shows how people fought in the Middle Ages. At that time, battles were even held as part of legal proceedings. Regional martial arts clubs show that today's society is more about sports or about protection against violence.
