This paper explores the enduring issue of antisemitism, framed as “the oldest hatred,” through an interdisciplinary lens that integrates legal, political, and historical perspectives. By examining the persistence and evolution of antisemitism in modern society, the study underscores the importance of Holocaust education as a critical tool for understanding and combating prejudice and discrimination. Grounded in the analysis of existing legal frameworks, including those established by the International Holocaust Remembrance Alliance (IHRA) and the European Court of Human Rights, the paper investigates how state policies and linguistic manipulation have historically reinforced antisemitic ideologies. A Polish university academic staff survey reveals educators’ perspectives on Holocaust education’s relevance in contemporary education. The findings highlight the need for a multidimensional approach that fosters critical thinking, societal awareness, and empathy to prevent future atrocities. The study concludes that combining historical awareness, legal knowledge, and ethical engagement in Holocaust education is essential for combating rising antisemitism and fostering a more informed and inclusive society.
