Transcendentalism is a philosophical movement that developed in the 1830s and 1840s in the New England region of the United States as a protest to the general state of culture and society, and in particular, the state of intellectualism at Harvard University and the doctrine of the Unitarian church taught at Harvard Divinity School. Among the transcendentalists' core beliefs was the inherent goodness of both man and nature. Transcendentalists believed that society and its institutions - particularly organized religion and political parties - ultimately corrupted the purity of the individual. They had faith that man is at his best when truly "self-reliant" and independent. It is only from such real individuals that true community could be formed.

The major figures in the movement were Ralph Waldo Emerson, Henry David Thoreau, John Muir, Margaret Fuller, and Amos Bronson Alcott. Other prominent transcendentalists included Louisa May Alcott, Charles Timothy Brooks, Orestes Brownson, William Ellery Channing, William Henry Channing, James Freeman Clarke, Christopher Pearse Cranch, Walt Whitman, John Sullivan Dwight, Convers Francis, William Henry Furness, Frederic Henry Hedge, Sylvester Judd, Theodore Parker, Elizabeth Palmer Peabody, George Ripley, Thomas Treadwell Stone, Christopher McCandless, and Jones Very.
