Check out the text and our analysis of the Constitution's fundamental statement of the principles of freedom of religion, freedom of speech, and freedom of the press.

We've got a learning guide devoted to Congress' first major restriction on First Amendment rights to freedom of the press. The act was repealed in 1801.

Here's the World War I-era clampdown on press freedom in time of war.

This act criminalized speech made in favor of "overthrowing or destroying the government [...] by force or violence," and was mostly used to prosecute American communists during the Cold War era.

This was a landmark 1919 Supreme Court case that ruled that speech that presented a "clear and present danger" to national security was not protected by the First Amendment.

This 1964 Supreme Court decision made it harder to sue for libel, as it required evidence of "actual malice" in publishing information with "reckless disregard for the truth" to establish liability in libel cases involving public figures.

This 1957 Supreme Court case made it more difficult to suppress publications on the basis of obscenity in their content. It established that material could only be deemed obscene if "the dominant theme of the material, taken as a whole, appeals to the prurient interest."

This 1972 Supreme Court case granted state and local governments the authority to regulate objectionable publications according to their own "community standards" of decency.

This 1969 Supreme Court decision ruled that public school students do have First Amendment rights to freedom of expression in school.

This 1986 Supreme Court decision upheld the authority of schools to restrict students' ability to make "offensively lewd and indecent" speech disruptive to the educational mission.

The 2007 Supreme Court descision in Morse v. Frederick affirmed that school officials had a right to punish a student who displayed an offensive banner—"Bong Hits 4 Jesus"—just off school grounds during a school-sponsored activity.

This controversial 1988 Supreme Court decision established that most high-school newspapers do not have full rights to freedom of the press under the First Amendment.

This 2007 decision of the Seventh Circuit Court ruled, for the first time, that college newspapers could be subjected to the same restrictions on freedom of the press as high schools under the Hazelwood standard. The Supreme Court refused to hear the case, meaning that Hosty applies to student journalists in Illinois, Indiana, and Wisconsin, but not elsewhere in the country.
