Tracing the Roots of Jewishness.

The article presents a study on the genealogy of the Jews. It also cites the three groupings of Jews made by historians, namely, the Middle Eastern or Oriental Jews, the Sephardic Jews of Spain and Portugal, and the Ashkenazi Jews of Europe. The origin of the Jews is discussed by writer Arthur Koestler in his book, "The Thirteenth Tribe," while historian Shlomo Sand's opinion is contained in his book, "The Invention of the Jewish People."
