Johann “Rukeli” Trollmann (1907-1944) was a German Sinti boxer. He won the German light heavyweight title, only to have it stripped by the Nazis due to his heritage and "un-German" style. He endured forced sterilization, forced labour, and eventually died in a concentration camp, reportedly beaten to death by a kapo he had once defeated in a boxing match.
As every year on 23 August, the European Day of Remembrance for Victims of Totalitarian Regimes, the ENRS recalls those persecuted in the name of totalitarian and authoritarian ideologies.
