Civil Disobedience can be compared to Thoreau's other works on non-fiction, including his well-known work, Walden, which was written shortly before this essay. Other related essays include "Life Without Principle," "Slavery in Massachusetts," "A Plea for Captain John Brown," and "The Service." Works by other transcendentalist American writers, such as those by Ralph Waldo Emerson, Frederic Henry Hedge, Margaret Fuller, and Walt Whitman are also relevant.
