The demographic dispersion of Jews is generally described in three categories: Ashkenazi, Sephardi and Mizrahi. While Ashkenazi Jews make up the majority of world Jewry, the Feingold Postcard Collection focuses mainly on Jewish populations living in North Africa, which consisted of a combination of Sephardic and Mizrahi Jews. The term Sephardi designates the diaspora of Jewish people from Spain who migrated to Mediterranean regions, such as France and North Africa. Mizrahi Jews, on the other hand, originated in Persia and diverse locales in the Middle East and moved eastward. Mizrahi Jews were often seen as outsiders by both natives and other sects of Jews because they had dark skin, spoke different languages and had different customs.
