At the time of writing, one consequence of Israel’s response to the massacre that took place in Israel by Hamas on 7 October 2023 is an unprecedented surge in global antisemitism. This massacre was the largest mass murder of Jewish civilians since the Holocaust; its scale, brutality and sadism have led to comparisons with the Holocaust, and to more and deeper sensitivities and controversies in Holocaust Education. In an attempt to address this, the proposed chapter will discuss the relationship between Holocaust Education and Antisemitism Education, and its relevance to Religious Education (RE) in schools. Holocaust Education comprises learning about and from the Holocaust (Cowan and Maitles, Understanding and teaching Holocaust education. Sage, 2017). The former focuses on the historical narrative; the latter focuses on moral issues related to active citizenship. Research findings in England (Foster, Pettigrew and Pearce et al., What do students know and understand about the Holocaust? Evidence from English secondary schools. Centre for Holocaust Education, UCL Institute of Education, 2016, p. 1) were that 68% of students (n = 7952 students) were “unaware of what ‘antisemitism’ meant”. Similarly, during a group interview, following their return from a visit to Auschwitz-Birkenau organised by the Archdiocese of Glasgow, Scotland, each of the four students indicated that they did not understand the term “antisemitism” (Cowan & Maitles, 2017, p. 139). Further, Short’s discussion of the failings of learning from the Holocaust included the lack of reference to “the key role played by Christian antisemitism in preparing the groundwork for the Holocaust” (Short, Learning from genocide? A study in the failure of Holocaust education. Intercultural Education, 16(4), 367-380, 2005; Failing to learn from the Holocaust. In As the Witnesses Fall Silent: 21st Century Holocaust Education in Curriculum, Policy and Practice (pp. 455–468), 2015). Cowan and Maitles (2017, p. 56) further assert that historical antisemitism contributes to understanding present-day antisemitism. The proposed chapter will offer suggestions as to how Holocaust and Antisemitism Education can work closely together, and how RE teachers can contribute to this.
