The document summarizes the key provisions and origins of the First Amendment to the US Constitution. It protects freedom of religion, speech, press, assembly, and the right to petition the government. It originated from government attempts to censor free expression in England and the colonies. Notable cases like John Peter Zenger's trial established truth as a defense against seditious libel. Over time, the First Amendment has been interpreted to protect various forms of expression from government infringement through a system of judicial review and balancing tests.
