The term "Aryan" in this context was used in a sense widely accepted in scientific racism of the time, which assumed a Caucasian race which was sub-divided into Semitic, Hamitic and Aryan (Japhetic) subraces, the latter corresponding to the Indo-European language family. Nevertheless, the de facto primary objective was to create extensive profiling based on racial data.
The investigation for lineage was not obligatory as it was a major undertaking to research the original documents for birth and marriage. Many Nazi followers had already begun to research their lineage even before law required it (soon after the NSDAP took power on 30 January 1933).
One important law which was issued on 7 April 1933 (after the Nazi assumption of power) was called the Law for the Restoration of the Professional Civil Service, and it required all public servants to be of "Aryan" descent. The law, however, did not define the term "Aryan" and a subsequent regulation was issued on 11 April as the first legal attempt by the Third Reich to define who was, and who was not, a Jew. Germans aspiring for the document had to prove they didn't descent either from Jews or Slavs. The Ahnenpaß was given out to citizens of other countries, under the condition that they were of "German blood" and it itself stated that "wherever they might live in the world" Aryans were "e.g. an Englishman or a Swede, a Frenchman or a Czech, a Pole or an Italian".
„Als nicht arisch gilt, wer von nicht arischen, insbesondere jüdischen Eltern oder Großeltern abstammt. Es genügt, wenn ein Elternteil oder ein Großelternteil nicht arisch ist. Dies ist insbesondere dann anzunehmen, wenn ein Elternteil oder ein Großelternteil der jüdischen Religion angehört hat.“
Those are not Aryans who descend from non-Aryan, especially Jewish, parents or grandparents. It is sufficient (grounds for exclusion) for one parent or grandparent to be non-Aryan. This is particularly assumable if a parent or grandparent adhered to the Jewish religion.
The applicable fields were later enlarged under different laws to include lawyers, teachers, medical doctors and finally requiring a proven Aryan lineage even to attend high school or to get married. Usually, the lineage was investigated four generations back. The Ahnenpass cost .60 Reichsmark.
The Ahnenpass was not public record; the document was shown where required and returned to the bearer.
As a result, genealogical research particularly flourished in Germany during the Third Reich. Opposition clergy helped many racially persecuted individuals by providing them with fake passports as a personal document necessary for survival.
In the section "Rassegrundsatz" (i.e. Racial Tenet) in the Ahnenpaß it is stated:
„Dem Denken des Nationalsozialismus entsprechend, jedem anderen Volke volle Gerechtigkeit widerfahren zu lassen, ist dabei niemals von höher- oder minderwertigen, sondern stets nur von fremden Rasseneinschlägen die Rede.“
"In line with national socialist thinking which does full justice to all other peoples, there is never the expression of superior or inferior, but alien racial admixtures."
