In Europe, the Holocaust was not a secret. Even though the Nazi government controlled the German press and did not publicize mass shooting operations or the existence of killing centers, many Europeans knew that Jews were being rounded up and shot, or deported and murdered. Many individuals—in Germany and collaborators in the countries that Germany occupied or that were aligned with Germany during World War II—actively participated in the stigmatization, isolation, impoverishment, and violence culminating in the mass murder of six million European Jews.
People helped in their roles as clerks and confiscators of property; as railway and other transportation employees; as managers or participants in round-ups and deportations; as informants; sometimes as perpetrators of violence against Jews on their own initiative; and sometimes as hand-on killers in killing operations, notably in the mass shootings of Jews and others in occupied Soviet territories in which thousands of eastern Europeans participated as auxiliaries and many more witnessed.
Many more people—the onlookers who witnessed persecution or violence against Jews in Nazi Germany and elsewhere—failed to speak out as their neighbors, classmates, and co-workers were isolated and impoverished—socially and legally, then physically. Only a small minority publicly expressed their disapproval. Other individuals actively assisted the victims by purchasing food or other supplies for households to whom shops were closed; providing false identity papers or warnings about upcoming roundups; storing belongings for those in hiding that could be sold off little by little for food; and sheltering those who evaded capture, a form of help that, if discovered, especially in Nazi Germany and occupied eastern Europe, was punished by arrest and often execution.
