Amendment I (the First Amendment) of the United States Constitution is part of the United States Bill of Rights. It states:
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the government for a redress of grievances.
Thus, it prevents the United States Congress from passing any law which:
- establishes a religion
- restricts religious freedom
- restricts free speech
- restricts the freedom of the press
- restricts the right of the people to demonstrate against the government
