Answer: Anti-Semitism.
Step-by-step explanation:
Anti-Semitism implies intolerance towards Jews. It is a phenomenon that has been happening since ancient times. The Romans brutally treated the Jews. During the Middle Ages, Jews were considered fraudsters, and they were forbidden to engage in many trades. They were accused of being moneylenders and guilty of the crucifixion of Christ. It was not until the 1960s that the church rejected these accusations. Germany's most extreme anti-Semitism was shown during the Second World War when over 6 million Jews were killed.
