Judenzählung
Judenzählung ([ˈjuːdn̩ˌtsɛːlʊŋ], German for "Jew census / counting") was a measure instituted by the Imperial German Army's Oberste Heeresleitung (OHL) in October 1916, during the upheaval of World War I. Designed to confirm accusations of the lack of patriotism among German Jews, the census disproved the charges, but its results were not made public. However, its figures were published in an antisemitic brochure.
