The regency of Duke Ulrich was a time of transition for the Estates, as they authored a government based on collegiate principle, with four nobles acting as regents and two prelates as advisers. The Estates voiced the interests of the towns to the regency, but during the Swabian War this regency became opposed to the wishes of the local burghers, among whom the war was very unpopular. The Estates would continue to vote more men and money to the war, which would end in defeat for the Swabian League. The Estates would continue to exercise their right to approve taxation to the Duchy's frequent wars, a right that would be extremely tested during Ulrich's reign.
