Herzogtum Franken
The most influential of Louis's councillors were Hatto I and Solomon III (bishop of Constance). It was these two who assured that the royal court decided in favour of the Conradines against the Babenbergers in the matter of the Duchy of Franconia. They appointed Louis's nephew, Conrad as a duke. In 903 the Raffelstetten Customs Regulations were promulgated under Louis' reign, the first customs regulations in the East Frankish part of Europe.
