The Horatians and the Curiatians (German: Die Horatier und die Kuriatier) is a Lehrstück ("Schulstück" in the collected plays) by the German dramatist Bertolt Brecht written in collaboration with Margarete Steffin in 1933–34.
Commissioned by the Red Army, the play was printed in Moscow in 1936 but never performed until 1958, two years after Brecht's death.
Two letters (from August 29, 1935 and shortly thereafter) to Hanns Eisler document Brecht's frustration over the attempted long distance collaboration with the composer, also in exile.
[1] Thus, the work was initially published without a musical score.
In 1954, Brecht invited composer Kurt Schwaen to set the play to music.
