Existentialism and absurdism emerged as powerful literary movements in the mid-20th century, grappling with the human condition in a world shaken by war and uncertainty. These philosophies explored individual existence, freedom, and the search for meaning in an indifferent universe. Key figures like Sartre, Camus, and Beckett shaped these movements through their writings, influencing literature, drama, and philosophy. Their works continue to resonate, offering insights into alienation, authenticity, and the struggle to find purpose in an often absurd world.
