James Madison introduced 39 proposed amendments to the Constitution before the House of Representatives in 1789; the House approved 17 of these, 12 of which were ultimately approved by Congress. Ten amendments, now known as the Bill of Rights, went on be ratified by the states. One of the proposed amendment, havng to do with Congressional salaries, was ratified in 1992 and is now the 27th Amendment. The twelfth proposed amendment, concerning Congressional apportionment, was ratified by 11 states as of 1792 and is considered still pending—it would now require ratification by 27 more states.
