Derived from the Gothic bandwō 'sign, token', The term was used already in the 6th century, mentioned by Procopius, as a term for a battle standard, and soon came to be applied to the unit bearing such a standard itself. From the reign of Nikephoros I (802–811) it was the name for a subdistrict of the Byzantine thema.
