Leaves of Grass is a collection of nearly 400 poems by Walt Whitman. It is known for its celebration of individuality, democracy, nature, and the human body. Whitman's free verse style and unconventional themes were considered controversial in his time, but the collection is now regarded as a landmark in American literature.
Leaves of Grass was an important literary work of the American Renaissance, which emerged in the mid-19th century and marked a shift towards a distinctly American literature. The collection was groundbreaking for its celebration of everyday life and its rejection of traditional poetic forms. Whitman's influence can be seen in the work of later poets and writers, including Allen Ginsberg, Langston Hughes, and Jack Kerouac, among others.
