Some notable First Amendment court cases include:

Schenck v. United States, 1919: In this case, the Supreme Court upheld the conviction of Socialist Party activist Charles Schenck after he distributed fliers urging young men to dodge the draft during World War I.

Schenck v. United States helped define limits of freedom of speech, creating the clear and present danger standard, explaining when the government is allowed to limit free speech. In this case, the Supreme Court viewed draft resistant as dangerous to national security.

New York Times Co. v. United States, 1971: This landmark Supreme Court case made it possible for The New York Times and Washington Post newspapers to publish the contents of the Pentagon Papers without risk of government censorship.

The Pentagon Papers were a top-secret Department of Defense study of U.S. political and military involvement in Vietnam from 1945 to 1967. Published portions of the Pentagon Papers revealed that the presidential administrations of Harry Truman, Dwight D. Eisenhower, John F. Kennedy and Lyndon B. Johnson had all misled the public about the degree of U.S. involvement in Vietnam.

Texas v. Johnson, 1990: Gregory Lee Johnson, a youth communist, burned a flag during the 1984 Republican National Convention in Dallas, Texas to protest the Reagan administration.

The Supreme Court reversed a Texas courts decision that Johnson broke the law by desecrating the flag. This Supreme Court Case invalidated statutes in Texas and 47 other states prohibiting flag-burning.
