Right - The 1876 Aiguillette for Aides-De-Camp to the Sultan - was a unique item of rank insignia, Not only used in its conventional sense, as a working symbol of a staff-officer’s authority, it was also granted as an honour to various officers. The Annuaire oriental du commerce, de l'industrie, de l'administration et de la magistrature (Constantinople 1891) held at the Bibliothèque Nationale de France, annually published the full index of the Imperial Ottoman Government and this actually listed, not only the Feriks (or Generals of Division), whom were entitled Aides-de-Camp Honraires, to the Sultan. In the Ottoman Turkish empire the aide-de-camp was considered to be a title of honour; The Annuaire oriental du commerce, (Constantinople 1891), included in this list all the Lieutenants, Captains etc who were also entitled ‘Aides-de-Camp Honraires’.
Among the Aides-de-Camp Honraires, to the Sultan there are some notable foreign officers, such as:
There was a high level of importance associated with the role. It appears as well, that the title raised the status of these officers. Ottoman Turkish military ranks carried a corresponding aristocratic title. In the case of a Lieutenant’s rank this was normally “EFFENDI”. However, in the Annuaire, the named Lieutenants, who are entitled ‘Aides-de-Camp Honraires’, end their names with the aristocratic title of “BEY”, which was normally intended for the MAJOR rank and above.
