The U.S. Bill of Rights, ratified in 1791, arose from the historical context of the American Revolution and the debates surrounding the ratification of the Constitution. Concerns about potential government overreach and the protection of individual liberties prompted calls for a formal enumeration of rights. The Federalists, who initially opposed a Bill of Rights, recognized its necessity to secure support from Anti-Federalists who feared a strong central government. The Bill comprises the first ten amendments to the Constitution, safeguarding fundamental rights such as freedom of speech, religion, and the press, and establishing legal protections. These amendments laid the foundation for American civil liberties and continue to influence constitutional law.
