Definition - What does Sedition mean?

Justipedia explains Sedition
Sedition cases are very rare in the United States. The reason for this is because the First Amendment to the Constitution provides a very wide-reaching protection of free speech. Therefore, American citizens are free to speak out against or criticize the government in most cases without being viewed as seditious. However, if a person actively tries to plan a revolt against the government, and is caught, then they will be tried for sedition.
