Antisemitic tropes, also known as antisemitic canards or antisemitic libels, are antisemitic allegations about Jews as an ethnicity or Judaism as a religion.
Since the 2nd century, malicious allegations of Jewish guilt have become a recurring motif in antisemitic tropes, which take the form of libels, stereotypes or conspiracy theories. They typically present Jews as cruel, powerful or controlling, some of which also feature the denial or trivialization of historical atrocities against Jews. These tropes have led to pogroms, genocides, persecutions and systemic racism for Jews throughout history. Antisemitic tropes mainly evolved in monotheistic societies, whose religions were derived from Judaism, many of which were traceable to Christianity's early days. These tropes were mirrored by 7th-century Quranic claims that Jews were "visited with wrath from Allah" due to their supposed practice of usury and disbelief in his revelations. In medieval Europe, antisemitic tropes were expanded in scope to justify mass persecutions and expulsions of Jews. Particularly, Jews were repeatedly massacred over accusations of causing epidemics and "ritually consuming" Christian babies' blood.
