This book was written in 1895 by a Jewish-French socialist writer. This work vividly details the history of anti-Semitism from ancient times to the 19th century. Its narrative and description are essential for any serious interpretation of the eternal question of why the world has hated the Jews. A question that sometimes has taken different form of unspoken prejudice and direct manifestation like the mass killing in the Holocaust. The author raises many serious questions that always have been hidden.
