My primary historical interests are Jewish History and Military History, but as with most SCA members I am interested in just about anything Medieval.
My current focus in the area of Jewish History is Medieval Spanish or Sephardic History. Jews whose origins go back to Medieval Spain are referred to as Sephardi while those from Eastern Europe are called Ashkenazi.
