Based upon survey research and drawing upon literature by historians and social scientists, this article discusses what Auschwitz means to Poles and how perceptions of it have changed since the 1990s. The article shows that Auschwitz means to nearly all Poles genocide, the Polish martyrdom, and the Jewish Holocaust at the same time. It also identifies and analyzes the processes thereby the number of Poles perceiving Auschwitz as primarily Jewish has increased from minimal to a relative majority and the number of those perceiving Auschwitz as primarily Polish, once being a relative majority, has decreased, albeit still remains fairly high. The article argues that the perception of Auschwitz in Poland has considerably become "Judaized", "de-Polonized", "de-nationalized", and "de-Catholized". It also draws conclusions from the case study of the changing perceptions of Auschwitz for social memory studies.
