Ulrich Graf
Shortly after the First World War, Graf became a member of the German Workers' Party (DAP). Later, the DAP was renamed the National Socialist German Workers' Party (NSDAP; Nazi Party) and taken over by Adolf Hitler. Founded in 1920, the "Sturmabteilung" (SA) was the first of many paramilitary protection squads that worked to protect Nazi officials. These storm troopers, outfitted in brown uniforms, were initially charged with the duty of keeping order at Nazi Party meetings. They soon expanded their role to include disruption of rival political party's functions. Graf was an early member of the SA. In 1921, he became member number 2882 of the Nazi Party.
Nazi Party
In 1920, the Nazi Party officially announced that only persons of "pure Aryan descent [""]" could become party members and if the person had a spouse, the spouse also had to be a "racially pure" Aryan. Party members could not be related either directly or indirectly to a so-called "non-Aryan". Even before it had become legally forbidden by the Nuremberg Laws in 1935, the Nazis banned sexual relations and marriages between party members and Jews. Party members found guilty of "Rassenschande" ("racial defilement") were persecuted heavily, some members were even sentenced to death.
