Well first let’s start of with the basics… we all know this part had to do with Hitler and the Jews. But most of all… At the annual party rally held in Nuremberg in 1935, the Nazis announced new laws which institutionalized many of the racial theories prevalent in Nazi ideology. The laws excluded German Jews from Reich citizenship and prohibited them from marrying or having sexual relations with persons of "German or related blood." Ancillary ordinances to the laws disenfranchised Jews and deprived them of most political rights. There is a lot of history associated with it but in order to het the main idea you have to know Hitler, his army, and lastly the Jews that bad Hitler torchered. Hope this helps!
The Nuremberg Laws, as they became known, did not define a "Jew" as someone with particular religious beliefs. Instead, anyone who had three or four Jewish grandparents was defined as a Jew, regardless of whether that individual identified himself or herself as a Jew or belonged to the Jewish religious community. Many Germans who had not practiced Judaism for years found themselves caught in the grip of Nazi terror. Even people with Jewish grandparents who had converted to Christianity were defined as Jews.
For a brief period after Nuremberg, in the weeks before and during the 1936 Olympic Games held in Berlin, the Nazi regime actually moderated its anti-Jewish attacks and even removed some of the signs saying "Jews Unwelcome" from public places. Hitler did not want international criticism of his government to result in the transfer of the Games to another country. Such a loss would have been a serious blow to German prestige.
