The Ahnenpaß (literally, "ancestor pass") documented the Aryan lineage of citizens of Nazi Germany. It was one of the forms of the Aryan certificate (Ariernachweis) and issued by the "Reich Association of Marriage Registrars in Germany" (Reichsverband der Standesbeamten in Deutschland e. V.).
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; the Nazi ideology limited the category Aryan to certain subgroups, while excluding Slavs as non-Aryan. 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 were of Aryan descent. The Ahnenpass could be given out to citizens of other countries, under the condition that they were of "German blood" and it itself stated that Aryans could be located "wherever they might live in the world"  The Reich Legislative Gazette, i.e. the official Reichsgesetzblatt, did not use the phrase "of German blood", but instead used the terminology "German or racially related blood".
Those Poles, Czechs and others from German minorities who held citizenship of other countries were also known as Volksdeutsche. Ethnic(non-German) Poles, Czechs and other Slavs weren't considered Aryans by Nazi Germany A definition of Aryan that included all non-Jewish Europeans was deemed unacceptable by Nazis, and Expert Advisor for Population and Racial Policy included a definition defining Aryan as someone who is "tribally" related to "German blood"
„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 two generations back. The Ahnenpass cost 0.6 Reichsmarks.
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.
