The First Amendment, ratified in 1791, protects five fundamental freedoms: speech, press, religion, assembly, and petition. These rights form the cornerstone of American democracy, safeguarding individual liberties and promoting the free exchange of ideas essential for self-governance. From historical origins to modern challenges, the First Amendment has evolved through landmark court cases and societal changes. While it provides robust protections for expression, there are limitations on certain forms of speech, and courts continue to grapple with applying its principles to new technologies and social issues.
