United States Bill of Rights
Due largely to the efforts of Representative James Madison, who studied the deficiencies of the Constitution pointed out by anti-federalists and then crafted a series of corrective proposals, Congress approved twelve articles of amendment on September 25, 1789, and submitted them to the states for ratification. Contrary to Madison's proposal that the proposed amendments be incorporated into the main body of the Constitution (at the relevant articles and sections of the document), they were proposed as supplemental additions (codicils) to it. Articles Three through Twelve were ratified as additions to the Constitution on December 15, 1791, and became Amendments One through Ten of the Constitution. Article Two became part of the Constitution on May 5, 1992, as the Twenty-seventh Amendment. Article One is still pending before the states.
