John Peter Zenger's trial in 1735 was a landmark case in the history of American journalism and free speech, centered around the question of libel against the colonial government. Zenger, a New York newspaper publisher, was accused of publishing articles that criticized the governor, William Cosby, which led to his arrest and trial. The trial ultimately established the precedent that truth could be used as a defense against charges of libel, laying a foundational principle for freedom of the press as later enshrined in the First Amendment.
