The Forty Days of Musa Dagh is a 1933 novel by the Austrian-Jewish author Franz Werfel. Based on the events at Musa Dagh in 1915 during the Armenian genocide in the Ottoman Empire, the book played a role in organizing the Jewish resistance under Nazi rule. It was passed from hand to hand in Jewish ghettos in Nazi-occupied Europe, and it became an example and a symbol for the Jewish underground throughout Europe. The Holocaust scholars Samuel Totten, Paul Bartrop and Steven L. Jacobs underline the importance of the book for many of the ghettos' Jews: "The book was read by many Jews during World War II and was viewed as an allegory of their own situation in the Nazi-established ghettos, and what they might do about it."
