Vjekoslav Klaić pointed out that the title before 12th century is only among Croats documented, and did not consider a problem that Bajan was a personal name and not a title, as seen in the most accepted derivation of Slavic word (kral/lj, krol). He mentioned both thesis (from Turkic-Persian, and Slavic "bojan, bojarin"), as well the German-Gothic theory derivation from banner and power of ban and King's ban. Gjuro Szabo shared similar Klaić's viewpoint, and emphasized the widespread distribution of a toponym from India to Ireland, and particularly among Slavic lands, and considered it as an impossibility that had derived from a personal name of a poorly known khagan, yet from a prehistoric word "Ban" or "Pan".
