America’s literary history started with the influx of immigrants from various backgrounds and cultures. These diverse groups brought their own unique traditions and narratives, which initially shaped the early literary landscape. However, for a considerable period, American literature was heavily influenced by European cultural currents. It wasn't until after the Declaration of Independence that Americans began to recognize the need for a distinct and nationally representative literature. This realization sparked a growth in American literary expression, which reached its peak during the Civil War era. The conflict acted as a catalyst, pushing American literature into a flourishing phase.During this period, Romanticism emerged as a prominent literary movement, emphasizing individualism and intuition. Figures like Ralph Waldo Emerson, a key proponent of Transcendentalism, played a crucial role in shaping American thought and literature. This era was marked by an explosion of creative works, much like the blooming of flowers in spring. Diverse forms of writing, ranging from poetry to prose, flourished, enriching American literature and contributing to the development of High Romanticism.However, the Civil War also brought about social upheaval, leading to a shift in literary themes. Writers began to focus more on local life, critical realism, and the darker aspects of society. This period saw an increase in works that delved into the realities of everyday life and the societal issues of the time. After the First World War, a sense of disillusionment and confusion permeated American society. This context gave rise to Modern American literature, characterized by a more experimental and fragmented approach to storytelling.My paper explores these periods in chronological order to provide a comprehensive overview of American literature's development. By tracing the evolution from early immigrant influences to the complex themes of Modernism, I aim to highlight the dynamic nature of American literary expression and its enduring impact on cultural identity.Keywords: National Literature, Romanticism, Transcendentalism, Local Color, Realism, Modern Literature
