List of proposed amendments to the United States Constitution


Hundreds of proposed amendments to the United States Constitution are introduced during each session of the United States Congress. From 1789 through January 3, 2017, approximately 11,699 measures have been proposed to amend the United States Constitution. Collectively, members of the House and Senate typically propose around 200 amendments during each two-year term of Congress. Most however, never get out of the Congressional committees in which they were proposed, and only a fraction of those that do receive enough support to win Congressional approval to actually go through the constitutional ratification process. Some proposed amendments are introduced over and over again in different sessions of Congress. It is also common for a number of identical resolutions to be offered on issues that have widespread public and congressional support.
Since 1789, Congress has sent 33 constitutional amendments to the states for ratification. Of these, 27 have been ratified. The framers of the Constitution, recognizing the difference between regular legislation and constitutional matters, intended that it be difficult to change the Constitution; but not so difficult as to render it an inflexible instrument of government, as the amendment mechanism in the Articles of Confederation, which required a unanimous vote of thirteen states for ratification, had proven to be. Therefore, a less stringent process for amending the Constitution was established in Article V.

Amending process

Amending the United States Constitution is a two-step process. Proposals to amend it must be properly adopted and ratified before becoming operative. A proposed amendment may be adopted and sent to the states for ratification by either:
The latter procedure has never been used. To become part of the Constitution, an adopted amendment must be ratified by either:
The decision of which ratification method will be used for any given amendment is Congress' alone to make, as is the decision to set a ratification deadline. Only for the 21st amendment was the latter procedure invoked and followed. Upon being properly ratified, an amendment becomes an operative addition to the Constitution.
