The First Amendment to the U.S. Constitution protects the freedom of speech, religion and the press. It also protects the right to peaceful protest and to petition the government. The amendment was adopted in 1791 along with nine other amendments that make up the Bill of Rights – a written document protecting civil liberties under U.S. law. The meaning of the First Amendment has been the subject of continuing interpretation and dispute over the years. Landmark Supreme Court cases have dealt with the right of citizens to protest U.S. involvement in foreign wars, flag burning and the publication of classified government documents.
