This is a complete list of all ratified and unratified 'amendments to the United States Constitution' which have received the approval of the
Congress. The procedure for amending the Constitution is governed by
Article V of the original text. There have been
Proposals for amendments to the United States Constitution for amendments introduced in Congress, but not submitted to the states.
Ratified amendments
There are currently twenty-seven articles of amendment to the United States Constitution. The first ten of these were ratified simultaneously and are known as the "
Bill of Rights".
Notes
# The first ten amendments and the twenty-seventh amendment to the Constitution were proposed as part of a group of ''twelve'' proposed amendments on
September 251791. The first two of these twelve were not ratified immediately. What we know today as the First through Tenth Amendments were actually the third through twelfth items on the list. The second of the proposed amendments eventually became the Twenty-seventh Amendment, its ratification being completed over 200 years later, in 1992. The first proposed amendment, the "
Congressional Apportionment Amendment", has yet to be ratified.
#
June 151804, is the date the Twelfth Amendment was ratified by the
New Hampshire legislature. However, the New Hampshire Governor vetoed the ratification on
June 201804. It is widely believed that a state's governor lacks the power to approve or veto a ratification made by that state's legislature. (See ''
Hollingsworth v. Virginia'' (
1798).) If the veto was effective, then the amendment nevertheless became part of the Constitution on
July 271804, when it was ratified by
Tennessee.
#
July 91868, is the date the Fourteenth Amendment received its 28th ratification, accounting for 3/4ths of the states in the Union at the time. However, prior to that date,
Ohio and
New Jersey had "withdrawn" their earlier ratifications of the amendment. Such withdrawals are generally held to be ineffective. If the withdrawals ''were'' effective, then the amendment nevertheless became part of the Constitution on
July 131868, when
Georgia ratified it.
#
February 31870, is the date the Fifteenth Amendment received its 28th ratification, accounting for 3/4ths of the states in the Union at the time. However, prior to that date,
New York had "withdrawn" its earlier ratification of the amendment. Such withdrawals are generally held to be ineffective. If one assumes that the withdrawal ''was'' effective, then the amendment nevertheless became part of the Constitution on
February 171870, when
Nebraska ratified it.
Unratified proposed amendments
Before an amendment can take effect, it must be proposed to the states by a two-thirds vote of both houses of Congress, and ratified by three-quarters of the states. (''See''
Article Five of the United States Constitution.) Six amendments proposed by Congress have failed to be ratified by the appropriate number of states' legislatures. Four of these amendments are still technically pending before state lawmakers—the other two have expired by their own terms.
