The national ethos was in search of non controversial heroes.
A staunch prop to King and country, Joan of Arc was an acceptable symbol to the monarchists.
As a patriot and the daughter of commoners, she was seen as one prototype of the low-born volunteers (the soldats de l'an II) who had victoriously fought for revolutionary France in 1802 and as such could be claimed by the Republicans.
As a religious martyr, she was also popular in the powerful Catholic community.
De Charmette's Orleanide, today largely forgotten, was another attempt to magnify the national ethos as writers like Virgil (the Aeneid), or Camoens (the Lusiad) had done for Rome and Portugal.
