The present study is the first of its kind to deal with Eastern European Karaite historical thought. It focuses on the social functions of Karaite historical narratives concerning the rise of Karaism from the Middle Ages to the nineteenth century. The book also deals with the image of Karaism created by Protestants, and with the perception of Karaism by some leaders of the Haskalah movement, especially the scholars of Hokhmat Israel. In both cases, Karaism was seen as an orientalistic phenomenon whereby the “enlightened” European scholars romanticized the “indigenous” people, while the Karaites (themselves), adopted this romantic images, incorporating it into their own national discourse. Finally, the book sheds new light on several conventional notions that shaped the study of Karaism from the nineteenth century.
