Brecht developed the combined theory and practice of his "Epic theatre" by synthesizing and extending the experiments of Erwin Piscator and Vsevolod Meyerhold to explore the theatre as a forum for political ideas and the creation of a critical aesthetics of dialectical materialism.

Epic Theatre proposed that a play should not cause the spectator to identify emotionally with the characters or action before him or her, but should instead provoke rational self-reflection and a critical view of the action on the stage.
Brecht thought that the experience of a climactic catharsis of emotion left an audience complacent.
Instead, he wanted his audiences to adopt a critical perspective in order to recognise social injustice and exploitation and to be moved to go forth from the theatre and effect change in the world outside.
For this purpose, Brecht employed the use of techniques that remind the spectator that the play is a representation of reality and not reality itself.
By highlighting the constructed nature of the theatrical event, Brecht hoped to communicate that the audience's reality was equally constructed and, as such, was changeable.

Brecht's modernist concern with drama-as-a-medium led to his refinement of the "epic form" of the drama.
This dramatic form is related to similar modernist innovations in other arts, including the strategy of divergent chapters in James Joyce's novel Ulysses, Sergei Eisenstein's evolution of a constructivist "montage" in the cinema, and Picasso's introduction of cubist "collage" in the visual arts.

One of Brecht's most important principles was what he called the Verfremdungseffekt (translated as "defamiliarization effect", "distancing effect", or "estrangement effect", and often mistranslated as "alienation effect").
This involved, Brecht wrote, "stripping the event of its self-evident, familiar, obvious quality and creating a sense of astonishment and curiosity about them".
To this end, Brecht employed techniques such as the actor's direct address to the audience, harsh and bright stage lighting, the use of songs to interrupt the action, explanatory placards, the transposition of text to the third person or past tense in rehearsals, and speaking the stage directions out loud.

In contrast to many other avant-garde approaches, however, Brecht had no desire to destroy art as an institution; rather, he hoped to "re-function" the theatre to a new social use.
In this regard he was a vital participant in the aesthetic debates of his era—particularly over the "high art/popular culture" dichotomy—vying with the likes of Theodor W. Adorno, György Lukács, Ernst Bloch, and developing a close friendship with Walter Benjamin.
Brechtian theatre articulated popular themes and forms with avant-garde formal experimentation to create a modernist realism that stood in sharp contrast both to its psychological and socialist varieties. "
Brecht's work is the most important and original in European drama since Ibsen and Strindberg," Raymond Williams argues, while Peter Bürger dubs him "the most important materialist writer of our time."

Brecht was also influenced by Chinese theatre, and used its aesthetic as an argument for Verfremdungseffekt.
Brecht believed, "Traditional Chinese acting also knows the alienation [sic] effect, and applies it most subtly... The [Chinese] performer portrays incidents of utmost passion, but without his delivery becoming heated."
Brecht attended a Chinese opera performance and was introduced to the famous Chinese opera performer Mei Lanfang in 1935.
However, Brecht was sure to distinguish between Epic and Chinese theatre.
He recognized that the Chinese style was not a "transportable piece of technique," and that Epic theatre sought to historicize and address social and political issues.

Brecht used his poetry to criticize European culture, including Nazis, and the German bourgeoisie.
Brecht's poetry is marked by the effects of the First and Second World Wars.
