Published in 1916 as a cautionary tale, America Fallen imagines a terrifying future in which the United States becomes the next victim of global war. Drawing on the recent devastation of World War I, the story portrays a sudden and catastrophic invasion that overwhelms American defenses. Through vivid descriptions of destroyed cities, military failures, and public panic, the narrative reflects early 20th-century anxieties about national vulnerability and international power. Combining military speculation with political commentary, this work stands as an early example of dystopian and alternate history fiction, urging readers to consider the fragility of peace and the dangers of complacency.
