 As during the late Middle Ages, the bishops of Würzburg used the nominal title of Duke of Franconia during the time of the Imperial Circle.In 1559, the Franconian Circle was given jurisdiction over coinage ("Münzaufsicht") and, in 1572, was the only Circle to issue its own police ordinance.Members of the Franconian Circle included the imperial cities, the prince-bishoprics, the Bailiwick of Franconia of the Teutonic Order and several counties.
