Even though self-critical dealing with the past has not been an official criterion for joining the EU, the founding of the Task Force for International Cooperation on Holocaust Education, Remembrance, and Research and the Holocaust conference in Stockholm at the beginning of 2000 seem to have generated informal standards of confronting and exhibiting the Holocaust in the context of “Europeanization of Memory.” Comparative analysis shows that post-Communist museums dealing with the World War II period perform in the context of those informal standards. Both the Jasenovac Memorial Museum in Croatia and the Museum of the Slovak National Uprising in Banská Bystrica were founded in the Communist era and played an important role in supporting the founding myths of the two countries. Both were subjected to historical revisionism during the 1990s. In the current exhibitions from 2004/2006, both memorial museums stress being part of Europe and refer, to “international standards” of musealization, while the Jasenovac memorial claims to focus on “the individual victim.” But stressing the European dimension of resistance and the Holocaust obscures such key aspects as the civil war and the responsibility of the respective collaborating regime.
