Anti-Semitism ("hostility toward or discrimination against Jews as a religious or racial group") is notably exposed within Daniel Deronda. This term was coined by Wilhelm Marr, a German agitator (born in Magdeburg, Germany), to "designate the anti-Jewish campaigns under way in central Europe. This would eventually lead to Nazi anti-Semitism (or the Holocaust) because of the racist dimension which targeted Jews. 

In the novel, we see the contrast between Mirah Cohen (the poor Jewish girl) and Gwendolen Harleth (the upper-class woman who marries for money). We also deal with Daniel's internalized anti-semitism which he learns to face in the discovery that he, himself, is Jewish; in the end, he marries Mirah and commits to establishing a Jewish homeland in Palestine.
