In this paper, I will try to seek answers to the following questions: (1) Why, in Die Grundlagen der Arithmetik, did Frege believe that the solution to the Julius Caesar problem must be found ? (2) Why didn't Frege deal with the Julius Caesar problem in Grundgesezte der Arithmetik, in spite of the fact that he was well aware of the difficulties involved with it in the context of Grundgesezte? In exploring these questions, I will investigate the various contexts in which the Julius Caesar problem arises.
