The Bill of Rights holds critical significance in the United States as it outlines the fundamental rights and protections afforded to citizens. Ratified in 1791, it consists of the first ten amendments to the Constitution, ensuring essential liberties such as freedom of speech, religion, and assembly. The Bill of Rights serves as a safeguard against government overreach, affirming individual rights that cannot be infringed upon by governmental power. Its existence has profoundly influenced American legal frameworks, shaping discussions around civil liberties and supporting ongoing movements advocating for rights protection and social justice.
