. "KEOKH records are relevant for the study of anti-Semitic radicalization and the Holocaust in Hungary for two chief reasons: it typically suspected foreigners and its reports on the raid it held tend to list the number of Jews concerned and expelled. In certain cases, so called Ostjuden are mentioned separately in these reports. Second, in 1941, KEOKH initiated and implemented the deportation of Jews from Hungary who could not prove their citizenship to newly occupied Galicia. This Hungarian anti-Jewish action eventually led to the first Nazi mass murder with over 10 000 victims. The collection of confidential papers mostly concern the organization of KEOKH, and files of people controlled by KEOKH."@eng .
