The First Amendment (Amendment I) to the United States Constitution is part of the Bill of Rights and protects American civil liberties. The amendment prohibits the making of any law pertaining to an establishment of a federal or state religion, impeding the free exercise of religion, abridging the freedom of speech, infringing on the freedom of the press, interfering with the right to peaceably assemble, or prohibiting the petitioning for a governmental redress of grievances.
