In July 1938 a group of prominent Italian scientists and intellectuals published the "Manifesto of Race," a mixture of racial and ideological antisemitic theories from ancient and modern sources. This treatise formed the basis for the Italian Racial Laws of October 1938. After its enactment Italian Jews lost their basic civil rights, positions in public offices, and their assets. Their books were prohibited: Jewish writers could no longer publish in magazines owned by Aryans. Jewish students who had begun their course of study were permitted to continue, but new Jewish students were barred from entering university. Levi had matriculated a year earlier than scheduled enabling him to take a degree.
