Walt Whitman's poetic style was shaped by a combination of free verse, democratic ideals, and a profound connection to American landscape and culture. Influences included Transcendentalism, reflecting a belief in individualism and the inherent goodness of people and nature. His use of cataloging and inclusive language embraced the diversity of the American experience. Additionally, exposure to Civil War realities deeply informed his writings, leading to a focus on humanity and the complexity of life and death. This distinct blend set him apart as an innovative American poet.
