Anti-Semitism is the irrational hatred, prejudice, or discrimination against Jews solely because of their Jewish identity. Anti-Semitism is one of the oldest and most enduring forms of hatred in human history, distinguishing it from other types of prejudice by its unique persistence, global spread, and intensity. anti-Semitism has ancient roots and has manifested throughout history in various forms, including religious, racial, and ethnic prejudices. From the accusations in the Middle Ages that Jews used the blood of Christians in religious rituals to the more modern racial theories that fueled the Holocaust, anti-Semitism adapts to the prevailing culture and continues to persist.
