Britannian Imperial Family

The Holy Empire of Britannia is ruled by the Imperial family, descended from the British Royal Family, which holds the highest positions within its government and military. The prince and princesses are ordered by number, which is determined by the status of their mothers, the imperial consorts. For example, Clovis is the Third Prince while Lelouch is (or was formerly) only the Eleventh Prince. The numbering of the Imperial princes and princesses is sorted by gender and possibly order of birth. For example, Euphemia is the Third Princess and Clovis is the Third Prince. The princes and princesses use the same surname prefix as their mother. The female members are entitled to elect a personal guardian called a "Knight," who are given authority and placed directly under their command, with their own unit. Cornelia's Knight is Guilford who, along with her, commands a unit of Knightmare Frames. Suzaku Kururugi also served as personal Knights to Euphemia and Lelouch after the latter became emperor. It can be assumed that there are more members in the imperial family as there is a gap between the Third and Eleventh Princes.
