On December 15, 1791, the Bill of Rights was ratified when Virginia gave its approval. It became Amendments 1-10 of the United States Constitution. From the article:
"The Bill of Rights draws influence and inspiration from the Magna Carta (1215), the English Bill of Rights (1689), and various later efforts in England and America to expand fundamental rights. George Mason’s Virginia Declaration of Rights formed the basis of the amendments that comprise the Bill of Rights.
Mason (1725-92), a native of Fairfax County, Virginia, championed individual liberties throughout his life. In 1776, he drafted the Virginia Declaration of Rights and a large part of Virginia’s state constitution. In 1787, as one of the most vocal members of the Constitutional Convention, Mason expressed great concern that assurances of individual liberties had not been incorporated into the Constitution, and, due to this concern and others, he elected not to sign the document.
The Bill of Rights answered Mason’s greatest concern and the concerns of many ratifying states. As a representative in the First Federal Congress, James Madison ushered seventeen amendments to the Constitution through the House of Representatives. These amendments were subsequently reduced to the twelve amendments passed by Congress and sent to the states on September 25, 1789. The first two proposed amendments, concerning the number of constituents for each representative and the compensation of members of Congress, were not ratified. By December 15, 1791, articles three through twelve were ratified by the required number of states and became known as the Bill of Rights.
The application of the rights enumerated in the first ten amendments to the Constitution frequently fosters contention. The United States Supreme Court is entrusted with the power to void acts of Congress that it finds to be in conflict with the Constitution or specifically with the Bill of Rights when the constitutionality of the acts arises in litigation. Thus, the amendments are frequently reinterpreted in fresh contexts and changing times."
