The theatre of the absurd is a dramatic genre that emerged in the mid-20th century, characterized by its focus on existential themes and the absurdity of human existence. This form of theatre often features illogical plots, nonsensical dialogue, and a lack of clear resolution, reflecting the post-war disillusionment and questioning of meaning in life. It emphasizes the breakdown of communication and the futility of human endeavors, aligning with existentialist ideas about the human condition.
