Thirty-three amendments to the Constitution of the United States have been proposed by the United States Congress and sent to the states for ratification since the Constitution was put into operation on March 4, 1789. Twenty-seven of those, having been ratified by the requisite number of states, are part of the Constitution. The first ten amendments were adopted and ratified simultaneously and are known collectively as the Bill of Rights. The 13th, 14th, and 15th amendments are collectively known as the Reconstruction Amendments. Six amendments adopted by Congress and sent to the states have not been ratified by the required number of states. Four of those amendments are still pending, one is closed and has failed by its own terms, and one is closed and has failed by the terms of the resolution proposing it. All 27 ratified and six unratified amendments are listed and detailed in the tables below.
