In what year was the Bill of Rights added to the Constitution?

The Bill of Rights, which comprises the first ten amendments to the United States Constitution, was ratified in 1791. This collection of amendments was designed to protect individual liberties and rights against potential government overreach. The process began in 1789 when James Madison introduced a set of amendments in response to calls from several states for greater constitutional protection of personal freedoms. After being proposed by Congress, the amendments were sent to the states for ratification, and by December 15, 1791, the required number of states had ratified the amendments, officially adding the Bill of Rights to the Constitution. The timeline reflects a significant commitment to civil liberties that continues to shape American legal and political discourse.
