This chapter addresses the political and intellectual context for Wagner’s revolutionary socialism. The nineteenth century stood in the light and shadow of the French Revolution, emboldened and fated to revisit and to relive many of its questions and practices. Wagner’s life mixed revolutionary theory and practice: in the Dresden uprising of 1849, but also in its ‘Vormärz’ prologue and in its apparently counter-revolutionary aftermath. Wagner experienced revolution on at least three geographical levels, European, German, and Saxon, the third receiving particular attention here. The focus is on Wagner’s most unambiguously revolutionary period, the 1840s and early 1850s, yet these ideas continued to play out in life, thought, and dramatic oeuvre: not only until completion of the Ring in 1874, Wagner’s revolutionary ‘fire cure’ reaching fulfilment in the final conflagration of Götterdämmerung, but in Parsifal and beyond. Earlier themes did not go unchanged; they provided shifting foundations for further dramatic exploration.
