Moses and Monotheism is a book written in 1939 by Sigmund Freud. The book consists of three essays and is an extension of Freud’s work on psychoanalytic theory as a means of generating hypotheses about historical events. Freud hypothesizes that Moses was not Hebrew, but actually born into Ancient Egyptian nobility and was probably a follower of Akhenaten, an ancient Egyptian monotheist.
It shocked many of its readers because of Freud's suggestion that Moses was actually born an Egyptian, rather than merely raised as an Egyptian.
