From what can be inferred from the composer’s correspondence and writings, Debussy was indifferent to political debate. It is noteworthy that the names of politicians are virtually absent from his letters, and that none of the major affairs or terrorist episodes that shook French public opinion are the subject of his public or private writings. This chapter describes France’s volatile politics and the impact of the Prussian invasion, the Commune (1871), the Dreyfus affair, the First World War, and other events that shaped the country. Relations with Germany and the catastrophe of the First World War are discussed. Although Debussy was directly affected by some political events, for example his father’s involvement in the Commune, he comes across as fairly apathetic in his few political pronouncements.
