By the tenth century, the term Ashkenaz was used to refer to Germany (Siddur Rav Amram Gaon). This may be because, as we have seen, Gomer, the father of Ashkenaz, was associated with '[[Magogite Nation|Germania]].' But according to this, the 'Reginia' mentioned in Josephus may have been the Rennus or Rhine area. There are numerous other sources that relate Ashkenaz to the Ashkuza mentioned in ancient writings, or to the Scythians from whom descends the term Scot. The nobility of a large nation in Scythia known as the Khazars is documented as having converted to Judaism and migrated west into central Europe.
