The Days of the Commune is a play by the twentieth-century German dramatist Bertolt Brecht. It dramatises the rise and fall of the Paris Commune in 1871. The play is an adaptation of the 1937 play The Defeat by the Norwegian poet and dramatist Nordahl Grieg. Brecht's collaborator Margarete Steffin translated the play into German in 1938 and Brecht began working on his adaptation in 1947. The process was driven by another Brecht collaborator, Ruth Berlau, who had introduced Brecht to Grieg in 1931.
