Wagner's involvement in left-wing politics abruptly ended his welcome in Dresden. Wagner was active among socialist German nationalists there, regularly receiving such guests as the conductor and radical editor August Röckel and the Russian anarchist Mikhail Bakunin. He was also influenced by the ideas of Pierre-Joseph Proudhon and Ludwig Feuerbach. Widespread discontent came to a head in 1849, when the unsuccessful May Uprising in Dresden broke out, in which Wagner played a minor supporting role. Warrants were issued for the revolutionaries' arrest. Wagner had to flee, first visiting Paris and then settling in Zürich where he at first took refuge with a friend, Alexander Müller.
