This document provides a history of libel law in the United States, beginning with seditious libel laws in the 1700s that criminalized criticism of the government. It discusses important court cases like the trial of John Peter Zenger in 1735 and the Sedition Act of 1798. In 1964, the Supreme Court case Times v. Sullivan established that public officials must prove "actual malice" to win a libel suit, protecting free debate. The standard was later extended to public figures as well. This established the modern framework for libel that balances free speech with protection from false statements.
