This five-page undergraduate paper examines civil disobedience, defines it as a form of non-violent protest in which concerned citizens deliberately violate a law they consider unjust, and provides examples from American history in which activists have used it to demonstrate the injustice of laws or government policies. The author discusses the advocacy of Henry David Thoreau and Martin Luther King for civil disobedience, and quotes from King’s “Letter from Birmingham Jail” and Thoreau’s famous nineteenth century essay on civil disobedience.
