In the meantime, the "Reichsverfassungskampagne" had not achieved any success regarding acceptance of the Constitution, but had managed to mobilize those elements of the population that were willing to commit violent revolution. In Saxony, this led to the May Uprising in Dresden, in the Bavarian part of the Rhenish Palatinate to the "Pfälzer Aufstand", a rising during which revolutionaries gained the "de facto" governmental power. On 14 May, Leopold, Grand Duke of Baden had to flee the country after a mutiny of the Rastatt garrison. The insurrectionists declared a Baden Republic and formed a revolutionary government headed by the Paulskirche deputy Lorenz Brentano. Together with Baden soldiers that had joined their side, they formed an army under the leadership of the Polish general Mieroslawski.
