Answer:
Between the 1950s and 1960s.
Step-by-step explanation:
This literary era was known as "Theatre of the Absurd", and it was characterised by a fascination with absurdity in all its forms – philosophical, dramaturgical, existential, emotional. This is a drama form that pushes theatre to extremes, and which asks probing questions about what reality (and unreality) really looks like. Often interpreted as a response to the challenges of living in a 20th-century world that seems devoid of meaning, it is frequently far more nightmarish than funny.
