Antisemitism is the world’s most enduring form of hatred, insidiously reinventing itself over the millennia.

Recent years have seen a dangerous resurgence of this hatred worldwide, threatening Jewish communities and undermining social cohesion. To effectively combat this phenomenon, there must first be a commonly agreed upon understanding of what it is. The International Holocaust Remembrance Alliance (IHRA) Working Definition of Antisemitism was devised for this very purpose.

Since the IHRA Working Definition of Antisemitism was adopted by the International Holocaust Remembrance Alliance (IHRA) in 2016, it has become the most widely recognized barometer in the collective effort against Jew-hatred, serving as an essential tool to identify and delineate all contemporary manifestations of this age-old societal scourge. The definition's proven effectiveness is rooted in the mainstream consensus that has coalesced around it worldwide - with a diverse array of international institutions and organizations, national and local governments, NGOs, universities, athletic clubs, and corporations using it as a non-legally binding guiding framework for recognizing modern-day iterations of antisemitism, training and educational programs, policymaking initiatives, and judicial process.

As of January 1, 2026, a total of 1,334 entities worldwide have adopted the IHRA Working Definition of Antisemitism. Among those, 47 national governments have done so, reflecting a growing international consensus that confronting antisemitism requires clear standards for identifying and addressing this enduring hatred.
