Whitman and Dickinson were two pioneering American poets who broke from traditional poetic forms. Whitman wrote in free verse without rhyme or strict structures. His poems explored themes of equality and democracy. Dickinson structured her poems with unique rhyme schemes and meters but kept them short. She explored themes of nature, death, and the human condition through precise language and imagery. Both poets expressed transcendentalist ideas through their modern poetic styles during the mid-19th century period of American literature.
