The focus of this paper is to examine Karl Marx’s (1818-1883) reason for writing “On the Jewish Question” (“Zur Judenfrage,” 1843). The position taken is the following: 1) Karl Marx was angry at something; 2) the anger was caused by Marx’s seeming helplessness in the face of the power of the Prussian state; 3) “On the Jewish Question,” while using seemingly accepted anti-Semitic language, was an attack on the Christian state which had forced itself upon the family of Marx.
