Racial segregation [SEP] Nazi Germany
German praise for America's system of institutional racism, which was previously found in Adolf Hitler's "Mein Kampf", was continuous throughout the early 1930s, and radical Nazi lawyers were advocates of the use of American models. Race based U.S. citizenship laws and anti-miscegenation laws directly inspired the two principal Nuremberg Laws—the Citizenship Law and the Blood Law. The ban on interracial marriage (anti-miscegenation) prohibited sexual relations and marriages between people classified as "Aryan" and "non-Aryan". Such relationships were called "Rassenschande" (race defilement). At first the laws were aimed primarily at Jews but were later extended to "Gypsies, Negroes and their bastard offspring".
