Rassenschande (German: [ˈʁasn̩ˌʃandə], lit. "race disgrace") or Blutschande (German: [ˈbluːtˌʃandə] (listen) "blood disgrace") was an anti-miscegenation concept in Nazi German racial policy, pertaining to sexual relations between Aryans and non-Aryans. It was put into practice by policies like the Aryan certificate requirement,[1] and later the Nuremberg Laws, adopted unanimously by the Reichstag on 15 September 1935. Initially, these laws referred predominantly to relations between Germans and non-Aryans.
