The historical document that extended human rights to all citizens in the United States is the Bill of Rights, ratified in 1791 as the first ten amendments to the Constitution. These amendments were designed to protect individual liberties and limit government power, addressing concerns raised during the ratification of the Constitution. Key rights guaranteed include freedom of speech, religion, and assembly, the right to bear arms, as well as protections against unreasonable searches and seizures. The Bill of Rights laid the foundation for civil liberties in the U.S. and has influenced democratic principles worldwide.
