Was ist? Ubersetzen Sie bitte.
Proof of "aryan ancestry"...or so I think.
During the third Reich every person had to give a complete, documented verification
about all ancestors
(parents, grandparents, great-grandparents, great-great grandparents + all uncles and aunts) over 100 years (
in some cases 150 years) back.
Without it you got no jobs, could not marry etc...well...popping up a jew or a gypsie or another "undesirable" of that time would had proofed fatal too!
This Nachweis was used to classify people after the Nuremburg laws..
