In his 1843 essay "On the Jewish Question", Karl Marx said the god of Judaism is money and accused the Jews of corrupting Christians. In 1850, German composer Richard Wagner published "Das Judenthum in der Musik" ("Jewishness in Music") under a pseudonym in the "Neue Zeitschrift für Musik". The essay began as an attack on Jewish composers, particularly Wagner's contemporaries (and rivals) Felix Mendelssohn and Giacomo Meyerbeer, but expanded to accuse Jewish influences more widely of being a harmful and alien element in German culture.
