The Theatre of the Absurd emerged in the 1950s as a response to World War II's horrors and existential philosophy. Playwrights like Beckett and Ionesco expressed life's meaninglessness through unconventional plays lacking clear plots or character development. This movement challenged traditional theatre forms, using circular dialogue and minimal sets to highlight human existence's futility. Influenced by avant-garde art and existentialist thinkers, absurdist plays continue to resonate with audiences grappling with life's uncertainties.
