In recent years, there has been a significant increase in Holocaust museums established worldwide, prompting numerous studies examining how they portray the Holocaust. Some researchers have emphasized the dominant roles of Yad Vashem and the United States Holocaust Memorial Museum in creating a canon and universalizing the Holocaust narrative. Others have highlighted the variations in Holocaust commemoration around the world. Additional studies have explored various aspects, including pedagogy and education, politics and nationalism, museum design and architecture, ethics, survivor testimonies, and more. This podcast delves into ongoing research funded by the Gerda Henkel Stiftung, investigating the role nationalism plays in shaping Holocaust narratives across seven countries within the European Union and beyond. The study, titled "When Nationalism Fails: A Comparative Study of Holocaust Museums," specifically focuses on Nazi collaboration, examining whether and how Holocaust museum exhibits address this subject and if nationalism affects the portrayal. As the research is still underway, this podcast serves as an initial platform for discussing the research rather than presenting its findings.
