The Constitution of the United States is the supreme law of the United States. It superseded the Articles of Confederation, the nation's first constitution, on March 4, 1789. Originally including seven articles, the Constitution delineates the frame of the federal government. The Constitution's first three articles embody the doctrine of the separation of powers, in which the federal government is divided into three branches: the legislative, consisting of the bicameral Congress ; the executive, consisting of the president and subordinate officers ; and the judicial, consisting of the Supreme Court and other federal courts. Article IV, Article V, and Article VI embody concepts of federalism, describing the rights and responsibilities of state governments, the states in relationship to the federal government, and the shared process of constitutional amendment. Article VII establishes the procedure subsequently used by the 13 states to ratify it. The Constitution of the United States is the oldest and longest-standing written and codified national constitution in force in the world.
Article Five of the United States Constitution describes the procedure for altering the Constitution. Under Article Five, the process to alter the Constitution consists of proposing an amendment or amendments, and subsequent ratification.
The Thirteenth Amendment to the United States Constitution abolished slavery and involuntary servitude, except as punishment for a crime. The amendment was passed by the Senate on April 8, 1864, by the House of Representatives on January 31, 1865, and ratified by the required 27 of the then 36 states on December 6, 1865, and proclaimed on December 18. It was the first of the three Reconstruction Amendments adopted following the American Civil War.
The Fifteenth Amendment to the United States Constitution prohibits the federal government and each state from denying or abridging a citizen's right to vote "on account of race, color, or previous condition of servitude." It was ratified on February 3, 1870, as the third and last of the Reconstruction Amendments.
The Nineteenth Amendment to the United States Constitution prohibits the United States and its states from denying the right to vote to citizens of the United States on the basis of sex, in effect recognizing the right of women to vote. The amendment was the culmination of a decades-long movement for women's suffrage in the United States, at both the state and national levels, and was part of the worldwide movement towards women's suffrage and part of the wider women's rights movement. The first women's suffrage amendment was introduced in Congress in 1878. However, a suffrage amendment did not pass the House of Representatives until May 21, 1919, which was quickly followed by the Senate, on June 4, 1919. It was then submitted to the states for ratification, achieving the requisite 36 ratifications to secure adoption, and thereby went into effect, on August 18, 1920. The Nineteenth Amendment's adoption was certified on August 26, 1920.
The Equal Rights Amendment (ERA) is a proposed amendment to the United States Constitution that would, if added, explicitly prohibit sex discrimination. It was written by Alice Paul and Crystal Eastman and first introduced in Congress in December 1923. With the rise of the women's movement in the United States during the 1960s, the ERA garnered increasing support, and, after being reintroduced by Representative Martha Griffiths in 1971, it was approved by the U.S. House of Representatives that year, and by the U.S. Senate in 1972, thus submitting the ERA to the state legislatures for ratification, as provided by Article V of the U.S. Constitution. The amendment's ratification in the states remains disputed to today, and it remains unratified.
The Twenty-third Amendment to the United States Constitution extends the right to participate in presidential elections to the District of Columbia. The amendment grants to the district electors in the Electoral College, as though it were a state, though the district can never have more electors than the least-populous state. How the electors are appointed is to be determined by Congress. The Twenty-third Amendment was proposed by the 86th Congress on June 16, 1960; it was ratified by the requisite number of states on March 29, 1961.
The Twenty-fourth Amendment of the United States Constitution prohibits both Congress and the states from requiring the payment of a poll tax or any other tax to vote in federal elections. The amendment was proposed by Congress to the states on August 27, 1962, and was ratified by the states on January 23, 1964.
The Twenty-seventh Amendment to the United States Constitution states that any law that increases or decreases the salary of members of Congress may take effect only after the next election of the House of Representatives has occurred. It is the most recently adopted amendment but was one of the first proposed.
A constitutional amendment is a modification of the constitution of a polity, organization or other type of entity. Amendments are often interwoven into the relevant sections of an existing constitution, directly altering the text. Conversely, they can be appended to the constitution as supplemental additions, thus changing the frame of government without altering the existing text of the document.
The District of Columbia's at-large congressional district is a congressional district encompassing all of Washington, D.C., the capital city of the United States. Article One of the United States Constitution instructs that only "States" may be represented in the United States Congress. Because the District of Columbia does not meet that criterion, the member elected from the at-large district is not permitted to participate in votes on the floor of the House. Instead, constituents of the seat elect a non-voting delegate to the chamber. Though the delegate lacks full voting privileges, they are permitted to sit on, cast votes in, and chair congressional committees and subcommittees. The delegate may also join party caucuses, introduce legislation, and hire staff to assist with constituent services.
The District of Columbia statehood movement is a political movement that advocates making the District of Columbia a U.S. state, to provide the residents of the District of Columbia with voting representation in the Congress and complete control over local affairs.
The Corwin Amendment is a proposed amendment to the United States Constitution that has never been adopted, but owing to the absence of a ratification deadline, could theoretically still be adopted by the state legislatures. It would have shielded slavery within the states from the federal constitutional amendment process and from abolition or interference by Congress.
Voting rights of citizens in the District of Columbia differ from the rights of citizens in the 50 U.S. states. The United States Constitution grants each state voting representation in both houses of the United States Congress. It defines the federal district as being outside of any state, and does not grant it any voting representation in Congress. The Constitution grants Congress exclusive jurisdiction over the District in "all cases whatsoever".
The Congressional Apportionment Amendment is a proposed amendment to the United States Constitution that addresses the number of seats in the House of Representatives. It was proposed by Congress on September 25, 1789, but was never ratified by the requisite number of state legislatures. As Congress did not set a time limit for its ratification, the Congressional Apportionment Amendment is still pending before the states. As of 2024, it is one of six unratified amendments.
A referendum on statehood for the District of Columbia was held on November 8, 2016. It was the first referendum on statehood to be held in the district. The District of Columbia was created following the passage of the Residence Act on July 9, 1790, which approved the creation of a national capital, the City of Washington on the Potomac River.
The Washington, D.C., Admission Act, often referred to simply as the D.C. Admission Act, is a bill introduced during the 116th United States Congress. The bill would grant Washington, D.C., admission into the Union as a state. The bill was originally introduced in the 116th Congress on January 3, 2019, and was reintroduced on January 4, 2021, and January 9, 2023, in the 117th and 118th Congresses. The United States House of Representatives passed it on April 22, 2021.
The Equality Amendment is a proposed Amendment to the U.S. Constitution by legal scholars Kimberlé Crenshaw and Catharine MacKinnon. It was first proposed in December 2019 in the Yale Law Journal. This proposal is an updated version of the Equal Rights Amendment written by Alice Paul from the National Women's Party, which was first proposed in 1923 and has not been ratified. This is different from the 2021 Equality Act, which has been proposed in Congress to prohibit discrimination based on biological sex, gender identity or sexual orientation.
