Gregory V
Gregory was a son of Otto I, Duke of Carinthia, a member of the Salian dynasty who was a grandson of Holy Roman Emperor Otto I. Gregory V succeeded John XV as pope when only twenty-four years of age. He was the chaplain of his cousin, Otto III, who presented him as candidate. Gregory V is often counted as the first German pope (or the second if Boniface II, an Ostrogoth, is counted).
