In Germany itself, the Ahnenpass and the Nuremberg Laws classified people as being of the Jewish race if they were descended from three or four grandparents enrolled in Jewish congregations. A person with one or two grandparents enrolled in a Jewish congregation could be classified as "Mischling", a crossbreed, of "mixed blood", if they were not a member of a Jewish congregation at the time the Nuremberg Laws were enacted. Only people with at least two of their grandparents of "German blood" could be German Reich's citizens, other Germans dropped into the new second class group of citizens, the so-called state citizens. If a person, with grandparents of the same religious combination, was enrolled as a member of a Jewish congregation in 1935 or would join later, they switched from the discriminatory class of Mischlinge into that of Geltungsjude, "Jew by legal validity", despite of not fulfilling the no less law-defined discriminating criterion of descending from three or four Jewish grandparents. Whereas every Mischling could anytime drop into the class of Geltungsjude by joining a Jewish congregation, the Nuremberg Laws provided for the unchanged classification of any Geltungsjude, regardless if she or he tried to evade harm by seceding from the Jewish congregation after 1935, considering such secessions as being of no effect as to the discrimination. Let alone people with three or four Jewish grandparents who themselves could never alter their law-defined racial categorisation as Jews. After 1935, any Mischling with two Jewish grandparents colloquially called a half-Jew, who married anybody who was classified as a Jew would drop into the discriminated class which was called Geltungsjude. Mischlinge with one Jewish grandparent were usually forbidden from marrying anybody with any Jewish grandparents. The Mischling Test was introduced in order to identify Europeans with Jewish blood and those who were tested were considered "Jews of the first or second degree."
