How did World War I influence Modernist literature?

World War I acted as a profound catalyst for Modernist literature, fundamentally altering the movement's trajectory by shattering prewar idealism and exposing the fragility of Western civilization. While early Modernism was characterized by a radical, utopian impulse to "make it new," the unprecedented scale of slaughter and destruction during the war introduced a pervasive sense of disillusionment, fragmentation, and anguish.123

The conflict rendered many traditional literary forms and styles obsolete, as writers felt they could no longer adequately capture the horror of the trenches or the chaos of the modern world. Postwar literature often reflected this "disenchantment," with authors employing experimental techniques—such as stream-of-consciousness, montage, and fragmented imagery—to mirror a fractured reality.2143

Seminal works like T.S. Eliot’s The Waste Land epitomized this shift, presenting a sterile, spiritually empty landscape that required active interpretation from the reader. Similarly, writers like D.H. Lawrence and Ezra Pound used their work to critique the sickness of a civilization that had descended into mass violence, often searching for meaning or rebirth amidst the ruins of the old order.12
