The latter conclusion by Šišić and Klaić was previously loosely opposed by Rački, who studying old historical records observed that ban could only be someone from one of the twelve Croatian tribes according to Supetar cartulary. This viewpoint is supported by the Chronicle of Duklja; Latin redaction; "Unaquaque in provincia banum ordinavit, id est ducem, ex suis consanguineis fratribus" ( in every province allocated a ban, and they were duke's consanguin brothers); Croatian redaction defines that all bans need to be by origin native and noble.
