From VIIIth to Xth century, an empire known as the Khazarian Kogonate dominated the eastern edge of Europe. At the height of its power it played an important role in the fate of Europe in the middle ages. Khazarian armies stopped the Arabian invasion during the earliest and most destructive part of Arabian conquests of Eastern Europe. An important historical topic is the conversion of Khazars who are not ethnically Jewish from paganism to Judaism. Besides the history of the Khazarian Empire from its formation to its demise, this book also describes the fate of the Khazarian Diaspora and the conversion of other nations to Judaism.
