The First Amendment to the US Constitution is one of the most important parts of the Bill of Rights. The First Amendment guarantees the right to free speech.
Thanks to the First Amendment, citizens of the United States have a right to speak freely, practice whatever religion they choose, and freely publish their opinions, among other rights. Along with the nine other amendments that make up the Bill of Rights, the First Amendment was adopted in 1791. For many US citizens, the First Amendment represents an important part of what it means to be an American.
