In the [[United States]], a '''state''' is a [[Federated state|constituent]] [[political entity]], of which there are 50. Bound together in a [[political union]], each state holds [[government]]al jurisdiction over a separate and defined geographic territory where it shares its [[sovereignty]] with the [[Federal government of the United States|federal government]]. Due to this [[dual sovereignty|shared sovereignty]], Americans are [[Citizenship of the United States|citizens]] both of the [[federal republic]] and of the [[Domicile (law)#United States|state in which they reside]].<ref>{{Cite web |last=Erler |first=Edward |title=Essays on Amendment XIV: Citizenship |url=http://www.heritage.org/constitution/#!/amendments/14/essays/167/citizenship |url-status=unfit |archive-url=https://web.archive.org/web/20170724095029/http://www.heritage.org/constitution/#!/amendments/14/essays/167/citizenship |archive-date=July 24, 2017 |access-date=January 12, 2016 |publisher=The Heritage Foundation |df=mdy-all}}</ref> State citizenship and residency are flexible, and no government approval is required to [[Freedom of movement under United States law|move between states]], except for persons restricted by certain types of court orders (such as [[paroled]] convicts and children of divorced spouses who share [[child custody]]).

[[State governments of the United States|State governments in the U.S.]] are allocated power by the people (of each respective state) through their individual [[State constitution (United States)|state constitutions]]. All are grounded in [[Republicanism in the United States|republican principles]] (this being required by the federal constitution), and each provides for a government, consisting of three branches, each with [[Separation of powers|separate and independent powers]]: [[Governor (United States)|executive]], [[State legislature (United States)|legislative]], and [[State court (United States)|judicial]].<ref name="faqtoc">{{Cite web |title=Frequently Asked Questions About the Minnesota Legislature |url=http://www.leg.state.mn.us/leg/faq/faqtoc.aspx?subject=1 |url-status=live |archive-url=https://web.archive.org/web/20131021082117/http://www.leg.state.mn.us/leg/faq/faqtoc.aspx?subject=1 |archive-date=October 21, 2013 |access-date=January 12, 2016 |publisher=[[Minnesota State Legislature]] |df=mdy-all}}</ref> States are divided into [[County (United States)|counties]] or county-equivalents, which may be assigned some local governmental authority but are not sovereign. County or county-equivalent structure varies widely by state, and states also create other [[Local government in the United States|local governments]].

States, unlike [[U.S. territories]], possess many powers and rights under the [[United States Constitution]]. States and their citizens are represented in the [[United States Congress]], a [[bicameral]] legislature consisting of the [[United States Senate|Senate]] and the [[United States House of Representatives|House of Representatives]]. Each state is also entitled to select a number of electors (equal to the total number of representatives and senators from that state) to vote in the [[Electoral College (United States)|Electoral College]], the body that directly elects the [[president of the United States]]. Additionally, each state has the opportunity to ratify [[Constitutional amendment#United States|constitutional amendments]], and, with the consent of Congress, two or more states may enter into [[interstate compact]]s with one another. The [[Police power (United States constitutional law)|police power of each state]] is also recognized.

Historically, the tasks of local [[Law enforcement in the United States#State|law enforcement]], [[Education in the United States|public education]], [[Health care in the United States|public health]], intrastate commerce regulation, and local [[Transportation in the United States|transportation]] and [[infrastructure]], in addition to [[Elections in the United States|local, state, and federal elections]], have generally been considered primarily state responsibilities, although all of these now have significant federal funding and regulation as well. Over time, the Constitution has been amended, and the interpretation and application of its provisions have changed. The general tendency has been toward centralization and [[Incorporation (Bill of Rights)|incorporation]], with the federal government playing a much larger role than it once did. There is a continuing debate over [[states' rights]], which concerns the extent and nature of the states' powers and sovereignty in relation to the federal government and the rights of individuals.

The Constitution grants to Congress the authority to [[Admission to the Union|admit new states]] into the Union. Since the establishment of the United States in 1776 by the [[Thirteen Colonies]], the number of states has expanded from the original 13 to 50. Each new state has been admitted on an [[equal footing]] with the existing states.<ref>{{Cite web |title=Doctrine of the Equality of States |url=https://law.justia.com/constitution/us/article-4/15-doctrine-of-the-equality-of-states.html |access-date=September 12, 2019 |website=Justia.com}}</ref> While the Constitution does not explicitly discuss [[secede|secession]] from the Union, the [[United States Supreme Court]], in ''[[Texas v.

==Background==

The 13 original states came into existence in July 1776 during the [[American Revolutionary War]] (1775–1783), as the successors of the [[Thirteen Colonies]], upon agreeing to the [[Lee Resolution]]<ref name="LeeReso">{{Cite web |date=June 7, 2018 |title=Delegate Discussions: The Lee Resolution(s) |url=https://declaration.fas.harvard.edu/blog/dd-lee-resolution |access-date=September 11, 2019 |website=The Declaration Resources Project |series=Course of Human Events |publisher=Harvard Faculty of Arts and Sciences |language=en}}</ref> and signing the [[United States Declaration of Independence]].<ref>{{Cite web |date=November 1, 2015 |title=Declaration of Independence: A Transcription |url=https://www.archives.gov/founding-docs/declaration-transcript |access-date=September 11, 2019 |website=National Archives |language=en}}</ref> Prior to these events each [[State (polity)|state]] had been a [[Kingdom of Great Britain|British]] [[British America|colony]];<ref name=LeeReso/> each then joined the first [[Perpetual Union|Union of states]] between 1777 and 1781, upon ratifying the [[Articles of Confederation]], the first U.S. constitution.<ref name="Zimmerman">{{Cite book |last=Zimmerman |first=Joseph F. |url={{GBurl|id=hDQpHzSrI0QC|p=4}} |title=Interstate Cooperation, Second Edition: Compacts and Administrative Agreements |publisher=SUNY Press |year=2012 |isbn=9781438442365 |pages=4–7 |language=en}}</ref><ref>{{Cite book |last=Jensen |first=Merrill |url={{GBurl|id=pFXLAMC1xtUC|p=184}} |title=The Articles of Confederation: An Interpretation of the Social-Constitutional History of the American Revolution, 1774–1781 |publisher=University of Wisconsin Press |year=1959 |isbn=978-0-299-00204-6 |pages=xi, 184}}</ref> Also during this period, the newly independent states developed their own individual [[State constitution (United States)|state constitutions]], among the earliest written constitutions in the world.<ref>{{Cite web |last=Beeman |first=Richard R. |title=The Constitutional Convention of 1787: A Revolution in Government |url=https://constitutioncenter.org/interactive-constitution/white-pages/the-constitutional-convention-of-1787-a-revolution-in-government |archive-url=https://web.archive.org/web/20190911035217/https://constitutioncenter.org/interactive-constitution/white-pages/the-constitutional-convention-of-1787-a-revolution-in-government |archive-date=September 11, 2019 |access-date=September 11, 2019 |publisher=National Constitution Center}}</ref> Although different in detail, these state constitutions shared features that would be important in the American constitutional order: they were [[Republicanism in the United States|republican]] in form, and separated power among three branches, most had bicameral legislatures, and contained statements, or a bill, of rights.<ref>{{Cite web |title=How the First State Constitutions helped build the Federal Constitution |url=https://www.crf-usa.org/images/pdf/gates/First-States-Constitution.pdf |url-status=live |archive-url=https://web.archive.org/web/20160804040953/https://www.crf-usa.org/images/pdf/gates/First-States-Constitution.pdf |archive-date=August 4, 2016 |access-date=September 21, 2019 |publisher=Constitutional Rights Foundation |pages=10–12}}</ref> Later, from 1787 to 1790, each of the states also ratified a new federal frame of government in the [[Constitution of the United States]].<ref>{{Cite web |date=August 15, 2016 |title=Observing Constitution Day |url=https://www.archives.gov/education/lessons/constitution-day/ratification.html |access-date=September 11, 2019 |website=National Archives |language=en}}</ref> In relation to the states, the U.S. Constitution elaborated concepts of [[federalism in the United States|federalism]].<ref>{{Cite web |last=Barnett |first=Randy E. |last2=Gerken |first2=Heather |date=July 6, 2016 |title=Article I, Section 8: Federalism and the overall scope of federal power |url=https://constitutioncenter.org/blog/article-i-section-8-federalism-and-the-overall-scope-of-federal-power/ |url-status=live |archive-url=https://web.archive.org/web/20220131093637/https://constitutioncenter.org/blog/article-i-section-8-federalism-and-the-overall-scope-of-federal-power/ |archive-date=January 31, 2022 |website=National Constitution Center}}</ref>

==Governments==
{{main|State governments of the United States}}
{{Further|Comparison of U.S. state governments}}
{{Political divisions of the United States}}

Under U.S. constitutional law, the 50 individual states and the United States as a whole are each sovereign jurisdictions.<ref name="Radan, 2007, p. 12">[[#Radan|Radan, 2007]], p. 12</ref> The states are ''not'' administrative divisions of the country; the [[Tenth Amendment to the United States Constitution]] reserves to the states or to the people all powers of government not delegated to the federal government.

Consequently, each of the 50 states reserves the right to organize its individual government in any way (within the broad parameters set by the U.S. Constitution and the [[Republican Guarantee]] enforced by Congress) deemed appropriate by its people, and to exercise all powers of government not delegated to the federal government by the Constitution.<ref>{{Cite web |title=10th Amendment US Constitution--Reserved Powers |url=https://www.govinfo.gov/content/pkg/GPO-CONAN-1992/pdf/GPO-CONAN-1992-10-11.pdf |url-status=live |archive-url=https://web.archive.org/web/20201207022205/https://www.govinfo.gov/content/pkg/GPO-CONAN-1992/pdf/GPO-CONAN-1992-10-11.pdf |archive-date=December 7, 2020 |access-date=December 11, 2020 |website=GovInfo}}</ref> A state, unlike the federal government, has un-enumerated [[Police power (United States constitutional law)|police power]], that is, the right to generally make all necessary laws for the welfare of its people.<ref>{{Cite book |last=Lehman |first=Jeffrey |url=https://archive.org/details/westsencyclopedi12lehm |title=West's Encyclopedia of American Law, Volume 8 |last2=Phelps |first2=Shirelle |date=2005 |publisher=Thomson/Gale |isbn=9780787663674 |edition=2 |url-access=registration}}</ref> As a result, while the governments of the various states share many similar features, they often vary greatly with regard to form and substance. No two state governments are identical.

===Constitutions===
The government of each state is structured in accordance with its individual constitution, all of which are written constitutions. Many of these documents are more detailed and more elaborated than their federal counterpart. For example, before its revision in 2022, the [[Constitution of Alabama]], contained 310,296 words, which is more than 40 times as many as the [[Constitution of the United States|U.S. Constitution]].<ref name="S&LG">{{Cite web |title=State and Local Government |url=https://bidenwhitehouse.archives.gov/about-the-white-house/our-government/state-local-government/ |url-status=live |archive-url=https://web.archive.org/web/20181030221842/https://www.whitehouse.gov/about-the-white-house/state-local-government/ |archive-date=October 30, 2018 |access-date=October 30, 2018 |publisher=[[The White House]] |location=Washington, D.C.}}</ref> In practice, each state has adopted a three-branch frame of government: executive, legislative, and judicial (even though doing so has never been required).<ref name="faqtoc"/><ref name=S&LG/>

Early in American history, four state governments differentiated themselves from the others in their first constitutions by choosing to self-identify as [[Commonwealth (U.S. state)|Commonwealth]]s rather than as [[state (polity)|states]]: [[Virginia]], in 1776;<ref name="Hornbook1994">{{Cite book |url=http://www.lva.virginia.gov/faq/va.asp#six |title=The Hornbook of Virginia History |publisher=Virginia Office of Graphic Communications |year=1994 |isbn=978-0-88490-177-8 |editor-last=Salmon |editor-first=Emily J. |edition=4th |location=Richmond, Virginia |page=88 |access-date=March 10, 2016 |editor-last2=Campbell |editor-first2=Edward D.

Consequently, while these four are states like the other states, each is formally a commonwealth because the term is contained in its constitution.<ref>{{Cite web |date=2016 |title=Why is Massachusetts a Commonwealth? |url=http://www.mass.gov/anf/research-and-tech/legal-and-legislative-resources/why-is-massachusetts-a-commonwealth.html |url-status=live |archive-url=https://web.archive.org/web/20160315111108/http://www.mass.gov/anf/research-and-tech/legal-and-legislative-resources/why-is-massachusetts-a-commonwealth.html |archive-date=March 15, 2016 |access-date=March 10, 2016 |website=Mass.gov |publisher=Commonwealth of Massachusetts}}</ref> The term, ''commonwealth'', which refers to ''a state in which the supreme power is vested in the people'', was first used in [[Colony of Virginia|Virginia]] during the [[Interregnum (England)|Interregnum]], the 1649–60 period between the reigns of [[Charles I of England|Charles I]] and [[Charles II of England|Charles II]] during which parliament's [[Oliver Cromwell]] as [[Lord Protector]] established a [[Republicanism|republican]] government known as the [[Commonwealth of England]]. Virginia became a royal colony again in 1660, and the word was dropped from the full title; it went unused until reintroduced in 1776.<ref name=Hornbook1994/>

====Executive====
{{Further|Governor (United States)}}
In each state, the chief executive is called the governor, who serves as both [[head of state]] and [[head of government]]. All governors are chosen by statewide [[direct election]]. The governor may approve or [[Veto power in the United States|veto]] bills passed by the state legislature, as well as recommend and work for the passage of bills, usually supported by their political party. In 44 states, governors have [[Line-item veto in the United States|line item veto]] power.<ref name="NCSLveto">{{Cite web |title=Separation of Powers--Executive Veto Powers |url=http://www.ncsl.org/research/about-state-legislatures/separation-of-powers-executive-veto-powers.aspx |url-status=live |archive-url=https://web.archive.org/web/20180228001648/http://www.ncsl.org/research/about-state-legislatures/separation-of-powers-executive-veto-powers.aspx |archive-date=February 28, 2018 |access-date=March 12, 2018 |publisher=National Conference of State Legislatures |df=mdy-all}}</ref> Most states have a [[plural executive]], meaning that the governor is not the only government official in the state responsible for its [[executive (government)|executive branch]]. In these states, executive power is distributed amongst other officials,<ref>{{Cite web |last=Regalado |first=Daniel M. |title=The Texas Plural Executive |url=https://courses.lumenlearning.com/odessa-texasgovernment/chapter/plural-executive/ |url-status=live |archive-url=https://web.archive.org/web/20180314042633/https://courses.lumenlearning.com/odessa-texasgovernment/chapter/plural-executive/ |archive-date=March 14, 2018 |access-date=March 12, 2018 |website=Texas Government (Chapter 4) |publisher=Lumen Learning |df=mdy-all}}</ref> elected by the people independently of the governor—such as the [[Lieutenant governor (United States)|lieutenant governor]], [[State attorney general|attorney general]], [[comptroller#United States|comptroller]], [[Secretary of State (U.S. state government)|secretary of state]], and others.

Elections of officials in the United States are generally for a [[Fixed-term election|fixed term]] of office. The constitutions of 19 states allow for citizens to remove and replace an elected public official before the end of their term of office through a [[recall election]].<ref name="NCSLrecall">{{Cite web |title=Recall of State Officials |url=http://www.ncsl.org/research/elections-and-campaigns/recall-of-state-officials.aspx |url-status=live |archive-url=https://web.archive.org/web/20180331184159/http://www.ncsl.org/research/elections-and-campaigns/recall-of-state-officials.aspx |archive-date=March 31, 2018 |access-date=March 12, 2018 |publisher=National Conference of State Legislatures |df=mdy-all}}</ref> Each state follows its own procedures for recall elections, and sets its own restrictions on how often, and how soon after a [[general election]], they may be held. In all states, the legislatures can remove state executive branch officials, including governors, who have committed serious abuses of their power from office. The process of doing so includes [[Impeachment in the United States|impeachment]] (the bringing of specific charges), and [[Impeachment trial|a trial]], wherein legislators act as a jury.<ref name=NCSLrecall/>

====Legislative====
{{Further|State legislature (United States)}}
The primary responsibilities of state legislatures are to enact state laws and appropriate money for the administration of public policy.<ref name=NCSLveto/> In all states, if the governor vetoes a bill (or a portion of one), it can still become law if the legislature overrides the veto (repasses the bill), which in most states requires a [[Supermajority#Two-thirds, or 66.66... percent|two-thirds vote]] in each chamber.<ref name=NCSLveto/> In 49 of the 50 states the legislature consists of two chambers: a lower house (variously called the House of Representatives, State Assembly, General Assembly or House of Delegates) and a smaller upper house, in all states called the Senate. The exception is the [[unicameral]] [[Nebraska Legislature]], meaning it has only a single chamber.<ref>{{Cite web |title=History of the Nebraska Unicameral: The Birth of a Unicameral |url=https://nebraskalegislature.gov/about/history_unicameral.php |url-status=live |archive-url=https://web.archive.org/web/20180304185859/https://nebraskalegislature.gov/about/history_unicameral.php |archive-date=March 4, 2018 |access-date=March 12, 2018 |publisher=Nebraska Legislature |location=Lincoln, Nebraska |df=mdy-all}}</ref> Most states have a [[Part-time job|part-time]] legislature (traditionally called a [[citizen legislature]]). Ten state legislatures are considered [[Full-time job|full-time]]; these bodies are more similar to the U.S. Congress than are the others.<ref name="NCSLftpt">{{Cite web |title=Full- and Part-time Legislatures |url=http://www.ncsl.org/research/about-state-legislatures/full-and-part-time-legislatures.aspx |url-status=live |archive-url=https://web.archive.org/web/20180307002645/http://www.ncsl.org/research/about-state-legislatures/full-and-part-time-legislatures.aspx |archive-date=March 7, 2018 |access-date=March 12, 2018 |publisher=National Conference of State Legislatures |df=mdy-all}}</ref>

Members of each state's legislature are chosen by direct election. In ''[[Baker v. Carr]]'' (1962) and ''[[Reynolds v. Sims]]'' (1964), the U.S. Supreme Court held that all states are required to elect their legislatures in such a way as to afford each citizen the same degree of representation (the [[one person, one vote]] standard). In practice, most states elect legislators from [[single-member district]]s, each of which has approximately the same population. Some states, such as Maryland and Vermont, divide the state into single- and multi-member districts. In this case, multi-member districts must have proportionately larger populations, e.g., a district electing two representatives must have approximately twice the population of a district electing just one. The [[Electoral system|voting systems]] used across the nation are: [[first-past-the-post]] in single-member districts, and [[multiple non-transferable vote]] in multi-member districts.

In 2013, there were a total of 7,383 legislators in the 50 state legislative bodies. They earned from $0 annually (New Mexico) to $90,526 (California). There were various per diem and mileage compensation.<ref>{{Cite news |last=Wilson |first=Reid |date=August 23, 2013 |title=How much are your legislators paid? |url=https://www.washingtonpost.com/blogs/govbeat/wp/2013/08/23/how-much-are-your-legislators-paid/ |url-access=registration |url-status=live |archive-url=https://web.archive.org/web/20130825171248/http://www.washingtonpost.com/blogs/govbeat/wp/2013/08/23/how-much-are-your-legislators-paid/ |archive-date=August 25, 2013 |access-date=August 26, 2013 |work=Washington Post |location=Washington, DC |pages=A2}}</ref>

====Judicial====
{{Further|State court (United States)}}
States can also organize their judicial systems differently from the [[United States federal courts|federal judiciary]], as long as they protect the federal constitutional right of their citizens to procedural [[due process]]. Most have a trial-level court, generally called a [[district court]], [[Superior court#United States|superior court]] or [[Circuit Court|circuit court]], a first-level [[Court of Appeals|appellate court]], generally called a court of appeal (or appeals), and a [[State supreme court|supreme court]]. Oklahoma and Texas have separate highest courts for criminal appeals. Uniquely, in New York State, the trial court is called the [[New York Supreme Court|Supreme Court]]; appeals go up first to the [[New York Supreme Court, Appellate Division|Supreme Court's Appellate Division]], and from there to its highest court, the [[New York Court of Appeals]].

State court systems exercise broad, plenary, and [[general jurisdiction]], in contrast to the federal courts, which are courts of limited jurisdiction. The overwhelming majority of criminal and civil cases in the United States are heard in state courts. Each year, roughly 30 million new cases are filed in state courts and the total number of judges across all state courts is about 30,000—for comparison, 1 million new cases are filed each year in federal courts, which have about 1,700 judges.<ref>{{Cite web |title=Federal vs. State Courts - Key Differences |url=https://litigation.findlaw.com/legal-system/federal-vs-state-courts-key-differences.html |url-status=live |archive-url=https://web.archive.org/web/20180514215512/https://litigation.findlaw.com/legal-system/federal-vs-state-courts-key-differences.html |archive-date=May 14, 2018 |access-date=May 14, 2018 |website=FindLaw |language=en-US}}</ref>

Most states base their legal system on English [[common law]] (with substantial statutory changes and incorporation of certain civil law innovations), with the notable exception of Louisiana, a former [[Louisiana (New France)|French colony]], which draws large parts of its legal system from French [[Civil law (legal system)|civil law]].

Only a few states choose to have the judges on the state's courts serve for life terms. In most states, the judges, including the justices of the highest court in the state, are either elected or appointed for terms of a limited number of years and are usually eligible for re-election or reappointment.

===Unitarism===

All states are [[unitary state]]s, not federations or aggregates of [[Local government in the United States|local governments]]. Local governments within them are created by and exist by virtue of state law, and local governments within each state are subject to the central authority of that particular state. State governments commonly delegate some authority to local units and channel policy decisions down to them for implementation.<ref>{{Cite web |title=Unitary system |url=https://www.britannica.com/topic/unitary-system |url-status=live |archive-url=https://web.archive.org/web/20161009084356/https://www.britannica.com/topic/unitary-system |archive-date=October 9, 2016 |access-date=August 13, 2016 |publisher=Encyclopædia Britannica, Inc.}}</ref> In a few states, local units of government are permitted a degree of [[home rule]] over various matters. The prevailing legal theory of state preeminence over local governments, referred to as [[John Forrest Dillon#Dillon's Rule|Dillon's Rule]], holds that,
{{Blockquote| A municipal corporation possesses and can exercise the following powers and no others: First, those granted in express words; second, those necessarily implied or necessarily incident to the powers expressly granted; third, those absolutely essential to the declared objects and purposes of the corporation—not simply convenient but indispensable; fourth, any fair doubt as to the existence of power is resolved by the courts against the corporation—against the existence of the powers.<ref>{{Cite journal |last=Dean |first=Kenneth d. |date=1976 |title=The Dillon Rule -- A limit on Local Government Powers |url=http://scholarship.law.missouri.edu/cgi/viewcontent.cgi?article=2323&context=mlr |url-status=live |journal=Missouri Law Review |volume=41 |issue=4 |page=548 |archive-url=https://web.archive.org/web/20161009115655/http://scholarship.law.missouri.edu/cgi/viewcontent.cgi?article=2323&context=mlr |archive-date=October 9, 2016 |access-date=August 13, 2016 |df=mdy-all}}</ref>}}

Each state defines for itself what powers it will allow local governments. Generally, four categories of power may be given to local jurisdictions:
{{Blockquote|
* Structural – power to choose the form of government, charter and enact charter revisions,
* Functional – power to exercise local self-government in a broad or limited manner,
* Fiscal – authority to determine revenue sources, set tax rates, borrow funds and other related financial activities,
* Personnel – authority to set employment rules, remuneration rates, employment conditions and collective bargaining.<ref>{{Cite web |title=Local Government Authority |url=http://www.nlc.org/build-skills-and-networks/resources/cities-101/city-powers/local-government-authority |url-status=dead |archive-url=https://web.archive.org/web/20160804131854/http://www.nlc.org/build-skills-and-networks/resources/cities-101/city-powers/local-government-authority |archive-date=August 4, 2016 |access-date=August 13, 2016 |publisher=[[National League of Cities]] |df=mdy-all}}</ref>}}

Each state admitted to the Union by Congress since 1789 has entered it on an [[equal footing]] with the original states in all respects.<ref name="4.3.1">{{Cite web |last=Forte |first=David F. |title=Essays on Article IV: New States Clause |url=http://www.heritage.org/constitution/#!/articles/4/essays/125/new-states-clause |url-status=unfit |archive-url=https://web.archive.org/web/20170724095029/http://www.heritage.org/constitution/#!/articles/4/essays/125/new-states-clause |archive-date=July 24, 2017 |access-date=January 12, 2016 |website=The Heritage Guide to the Constitution |publisher=The Heritage Foundation}}</ref> With the growth of [[states' rights]] advocacy during the [[antebellum period]], the Supreme Court asserted, in ''Lessee of Pollard v.

Under [[Article Four of the United States Constitution|Article IV of the Constitution]], which outlines the relationship between the states, each state is required to give [[Full Faith and Credit Clause|full faith and credit]] to the acts of each other's legislatures and courts, which is generally held to include the recognition of most contracts and criminal judgments, and before 1865, slavery status. Pursuant to the [[Extradition Clause]], a state must [[extradition|extradite]] people located there who have fled charges of "treason, felony, or other crimes" in another state if the other state so demands.<ref>{{cite journal |last1=Moses |first1=Ray |last2=Dally |first2=Carl E.F. |title=Interstate Extradition to Answer Criminal Charges |journal=Texas Law Journal |date=1966 |volume=9 |page=166}}</ref>

The full faith and credit expectation does have exceptions, some legal arrangements, such as professional licensure and marriages, may be state-specific, and until recently states have not been found by the courts to be required to honor such arrangements from other states.<ref name="interracial">{{Cite news |last=Adam Liptak |date=March 17, 2004 |title=Bans on Interracial Unions Offer Perspective on Gay Ones |url=https://www.nytimes.com/2004/03/17/us/bans-on-interracial-unions-offer-perspective-on-gay-ones.html?pagewanted=1 |url-status=live |archive-url=https://web.archive.org/web/20170525063730/http://www.nytimes.com/2004/03/17/us/bans-on-interracial-unions-offer-perspective-on-gay-ones.html?pagewanted=1 |archive-date=May 25, 2017 |access-date=February 20, 2017 |work=[[The New York Times]]}}</ref> Such legal acts are nevertheless often recognized state-to-state according to the common practice of [[comity]]. States are prohibited from discriminating against citizens of other states with respect to their [[human rights|basic rights]], under the [[Privileges and Immunities Clause]].

===With the federal government===
{{Further| Federalism in the United States}}
Under Article IV, each state is guaranteed a form of government that is grounded in republican principles, such as the [[consent of the governed]].<ref>{{Cite book |last=Ernest B. Abbott |url={{GBurl|id=crI0pYe2vmMC|p=52}} |title=Homeland Security and Emergency Management: A Legal Guide for State and Local Governments |last2=Otto J. Hetzel |publisher=American Bar Association |year=2010 |isbn=9781604428179 |page=52}}</ref> This guarantee has long been at the forefront of the debate about the rights of citizens vis-à-vis the government. States are also guaranteed protection from invasion, and, upon the application of the state legislature (or executive, if the legislature cannot be convened), from domestic violence. This provision was discussed during the [[1967 Detroit riot]] but was not invoked.
[[File:Map of all U.S. Federal Land.jpg|thumb|right|280px|Ownership of [[federal lands]] in the 50 states]]
The [[Supremacy Clause]] ([[Article Six of the United States Constitution#Supremacy|Article VI, Clause 2]]) establishes that the [[United States Constitution|Constitution]], [[Law of the United States|federal laws]] made pursuant to it, and [[Treaty|treaties]] made under its authority, constitute the supreme law of the land.<ref>{{Cite web |last=[[Cornell University Law School]] |title=Supremacy Clause |url=https://www.law.cornell.edu/wex/supremacy_clause |url-status=live |archive-url=https://web.archive.org/web/20180201142625/https://www.law.cornell.edu/wex/supremacy_clause |archive-date=February 1, 2018 |access-date=February 21, 2018 |publisher=law.cornell.edu}}</ref> It provides that [[State court (United States)|state courts]] are bound by the supreme law; in case of conflict between federal and state law, the federal law must be applied.

[[States' rights]] are understood mainly with reference to the [[Tenth Amendment to the United States Constitution|Tenth Amendment]]. The Constitution delegates some powers to the national government, and it forbids some powers to the states. The Tenth Amendment reserves all other powers to the states, or to the people. Powers of the [[U.S. Congress]] are [[Enumerated powers|enumerated]] in [[Article One of the United States Constitution#Section 8: Powers of Congress|Article I, Section 8]], for example, the power to declare war. Making treaties is one power forbidden to the states, being listed among other such powers in [[Article One of the United States Constitution#Section 10: Limits on the States|Article I, Section 10]].

Among the Article I enumerated powers of Congress is the power to regulate commerce. Since the early 20th century, the Supreme Court's interpretation of this "[[Commerce Clause]]" has, over time, greatly expanded the scope of [[federal power]], at the expense of powers formerly considered purely states' matters. The ''Cambridge Economic History of the United States'' says, "On the whole, especially after the mid-1880s, the Court construed the Commerce Clause in favor of increased federal power."<ref>{{Cite book |last=Stanley Lewis Engerman |url={{GBurl|id=6sDXBGMbrWkC}} |title=The Cambridge economic history of the United States: the colonial era |publisher=Cambridge University Press |year=2000 |isbn=978-0-521-55307-0 |page=[{{GBurl|id=6sDXBGMbrWkC|p=464}} 464]}}</ref> In 1941, the Supreme Court in ''[[United States v. Darby Lumber Co.|U.S. v. Darby]]'' upheld the [[Fair Labor Standards Act of 1938]], holding that Congress had the power under the Commerce Clause to regulate employment conditions.<ref>{{Cite web |title=United States v. Darby, 312 U.S. 100 (1941) |url=https://supreme.justia.com/cases/federal/us/312/100/ |access-date=October 30, 2018 |website=justia.com |publisher=Justia |location=Mountain View, California}}</ref> Then, one year later, in ''[[Wickard v. Filburn]]'', the Court expanded federal power to regulate the economy by holding that federal authority under the commerce clause extends to activities which may appear to be local in nature but in reality effect the entire national economy and are therefore of national concern.<ref>{{Cite book |last=David Shultz |url={{GBurl|id=I_f6Oo9H3YsC}} |title=Encyclopedia of the Supreme Court |publisher=Infobase Publishing |year=2005 |isbn=978-0-8160-5086-4 |page=[{{GBurl|id=I_f6Oo9H3YsC|p=522}} 522]}}</ref> For example, Congress can regulate railway traffic across state lines, but it may also regulate rail traffic solely within a state, based on the reality that intrastate traffic still affects interstate commerce. Through such decisions, argues law professor David F. Forte, "the Court turned the commerce power into the equivalent of a general regulatory power and undid the Framers' original structure of limited and delegated powers." Subsequently, Congress invoked the Commerce Clause to expand federal criminal legislation, as well as for social reforms such as the [[Civil Rights Act of 1964]]. Only within the past couple of decades, through decisions in cases such as those in ''[[United States v. Lopez|U.S. v. Lopez]]'' (1995) and ''[[United States v. Morrison|U.S. v. Morrison]]'' (2000), has the Court tried to limit the Commerce Clause power of Congress.<ref name="A1Essays">{{Cite web |last=Forte |first=David F. |title=Essays on Article I: Commerce among the States |url=https://www.heritage.org/constitution/#!/articles/1/essays/38/commerce-among-the-states |archive-url=https://web.archive.org/web/20120421180046/http://www.heritage.org/constitution#!/articles/1/essays/38/commerce-among-the-states |url-status=unfit |archive-date=April 21, 2012 |access-date=October 30, 2018 |website=Heritage Guide to the Constitution |publisher=Heritage Foundation}}</ref>

Although some objected that this infringes on states' rights, the Supreme Court upheld the practice as a permissible use of the Constitution's Spending Clause in ''[[South Dakota v. Dole]]'' {{ussc|483|203|1987}}.

As prescribed by Article I of the Constitution, which establishes the U.S. Congress, each state is represented in the Senate (irrespective of population size) by two senators, and each is guaranteed at least one representative in the House. Both senators and representatives are chosen in [[Direct election|direct popular elections]] in the various states. (Prior to 1913, senators were elected by state legislatures.) There are presently 100 senators, who are elected [[at-large]] to [[Classes of United States Senators|staggered terms]] of six years, with one-third of them being chosen every two years. Representatives are elected at large or from [[single-member district]]s to terms of two years (not staggered). The size of the House—presently 435 voting members—is set by [[Act of Congress|federal statute]]. Seats in the House are [[United States congressional apportionment|distributed]] among the states in proportion to the most recent constitutionally mandated decennial [[United States Census|census]].<ref>{{Cite web |last=Kristin D.

While the Constitution does set parameters for the election of federal officials, state law, not federal, regulates most aspects of elections in the U.S., including primaries, the eligibility of voters (beyond the basic constitutional definition), the running of each state's electoral college, as well as the running of state and local elections.

Article IV also grants to Congress the authority to admit new states into the Union. Since the establishment of the United States in 1776, the number of states has expanded from [[Thirteen Colonies|the original 13]] to 50. Each new state has been admitted on an equal footing with the existing states.<ref name=EoS/> Article IV also forbids the creation of new states from parts of existing states without the consent of both the affected states and Congress. This caveat was designed to give Eastern states that still had [[State cessions|Western land claims]] (including Georgia, North Carolina, and Virginia) to have a [[veto]] over whether their western counties could become states,<ref name=4.3.1/> and has served this same function since, whenever a [[List of U.S. state partition proposals|proposal to partition]] an existing state or states in order that a region within might either join another state or to create a new state has come before Congress.

Most of the states admitted to the Union after the original 13 were formed from an [[organized incorporated territories of the United States|organized territory]] established and governed by Congress in accord with its [[plenary power]] under Article IV, Section 3, [[Article Four of the United States Constitution#Clause 2: Property Clause|Clause 2]].<ref>{{Cite web |title=Property and Territory: Powers of Congress |url=http://law.justia.com/constitution/us/article-4/25-methods-of-disposing-property.html |url-status=live |archive-url=https://web.archive.org/web/20170525020637/http://law.justia.com/constitution/us/article-4/25-methods-of-disposing-property.html |archive-date=May 25, 2017 |access-date=April 8, 2016 |website=Justia.com}}</ref> The outline for this process was established by the [[Northwest Ordinance]] (1787), which predates the ratification of the Constitution. In some cases, an entire territory has become a state; in others some part of a territory has.

When the people of a territory make their desire for statehood known to the federal government, Congress may pass an [[enabling act]] authorizing the people of that territory to organize a [[constitutional convention (political meeting)|constitutional convention]] to write a state constitution as a step toward admission to the Union. Each act details the mechanism by which the territory will be admitted as a state following ratification of their constitution and election of state officers. Although the use of an enabling act is a traditional historic practice, a number of territories have drafted constitutions for submission to Congress absent an enabling act and were subsequently admitted. Upon acceptance of that constitution and meeting any additional congressional stipulations, Congress has always admitted that territory as a state.

In addition to the original 13, six subsequent states were never an organized territory of the federal government, or part of one, before being admitted to the Union.

Congress is under no obligation to admit states, even in those areas whose population expresses a desire for statehood. Such has been the case numerous times during the nation's history. In one instance, [[Mormon pioneers]] in [[Salt Lake City]] sought to establish the state of [[State of Deseret|Deseret]] in 1849. It existed for slightly over two years and was never approved by the [[United States Congress]]. In another, leaders of the [[Five Civilized Tribes]] (Cherokee, Chickasaw, Choctaw, Creek, and Seminole) in [[Indian Territory]] proposed to establish the state of [[State of Sequoyah|Sequoyah]] in 1905, as a means to retain control of their lands.<ref name="museum">{{Cite web |year=2005 |title=Museum of the Red River - The Choctaw |url=http://www.museumoftheredriver.org/choctaw.html |url-status=dead |archive-url=https://web.archive.org/web/20090615223442/http://www.museumoftheredriver.org/choctaw.html |archive-date=June 15, 2009 |access-date=August 4, 2009 |publisher=Museum of the Red River |df=mdy-all}}</ref> The proposed constitution ultimately failed in the U.S. Congress. Instead, the Indian Territory and [[Oklahoma Territory]] were both incorporated into the new state of Oklahoma in 1907. The first instance occurred while the nation still operated under the Articles of Confederation. The [[State of Franklin]] existed for several years, not long after the end of the American Revolution, but was never recognized by the Confederation Congress, which ultimately recognized [[North Carolina]]'s claim of sovereignty over the area. The territory comprising Franklin later became part of the Southwest Territory, and ultimately of the state of Tennessee.

Additionally, the entry of several states into the Union was delayed due to distinctive complicating factors. Among them, [[Michigan Territory]], which petitioned Congress for statehood in 1835, was not admitted to the Union until 1837, due to a [[Toledo War|boundary dispute]] with the adjoining state of Ohio. The [[Republic of Texas]] requested annexation to the United States in 1837, but fears about potential conflict with Mexico delayed the admission of Texas for nine years.<ref>{{Cite book |last=Winders |first=Richard Bruce |url={{GBurl|id=mcc9EciebFYC}} |title=Crisis in the Southwest: the United States, Mexico, and the Struggle over Texas |publisher=Rowman & Littlefield |year=2002 |isbn=978-0-8420-2801-1 |pages=[{{GBurl|id=mcc9EciebFYC|p=82}} 82], [{{GBurl|id=mcc9EciebFYC|p=92}} 92] |access-date=October 30, 2018 |via=[[Google Books]]}}</ref> Statehood for [[Kansas Territory]] was held up for several years (1854–61) due to a series of internal [[Bleeding Kansas|violent conflicts]] involving [[Free-Stater (Kansas)|anti-slavery]] and [[Border Ruffian|pro-slavery]] factions.

As with all U.S. territories, its residents do not have full representation in the United States Congress. Puerto Rico has limited representation in the U.S. House of Representatives in the form of a [[Resident Commissioner of Puerto Rico|Resident Commissioner]], a delegate with limited voting rights in the [[Committee of the Whole (United States House of Representatives)|Committee of the Whole House on the State of the Union]], but no voting rights otherwise.<ref name="rhg">{{Cite web |title=Rules of the House of Representatives |url=http://www.rules.house.gov/ruleprec/110th.pdf |url-status=dead |archive-url=https://web.archive.org/web/20100528025556/http://www.rules.house.gov/ruleprec/110th.pdf |archive-date=May 28, 2010 |access-date=July 25, 2010}}</ref>

===Washington, D.C.===
{{Main|District of Columbia statehood movement}}

The intention of the [[Founding Fathers of the United States|Founding Fathers]] was that the United States capital should be at a neutral site, not giving favor to any existing state; as a result, the District of Columbia was created in 1800 to serve as the [[seat of government]]. As it is not a state, the district does not have representation in the Senate and has a [[Delegate (United States Congress)|non-voting delegate]] in the House; neither does it have a sovereign elected government. Additionally, before [[ratification]] of the [[Twenty-third Amendment to the United States Constitution|23rd Amendment]] in 1961, district citizens did not get the [[Voting rights in the United States|right to vote]] in presidential elections.

The strong majority of residents of the District support statehood of some form for that jurisdiction – either statehood for the whole district or for the inhabited part, with the remainder remaining under [[federal jurisdiction (United States)|federal jurisdiction]]. In November 2016, Washington, D.C. residents voted in a [[District of Columbia statehood referendum, 2016|statehood referendum]] in which 86% of voters supported statehood for Washington, D.C.<ref>{{Cite web |date=November 7, 2016 |title=DC Voters Elect Gray to Council, Approve Statehood Measure |url=http://www.nbcwashington.com/news/local/DC-Election-Statehood-Council-Seats-400275901.html |url-status=live |archive-url=https://web.archive.org/web/20161109221442/http://www.nbcwashington.com/news/local/DC-Election-Statehood-Council-Seats-400275901.html |archive-date=November 9, 2016 |access-date=June 14, 2017 |website=nbcwashington.com}}</ref> For statehood to be achieved, it must be approved by Congress.<ref>{{Cite web |date=November 23, 2018 |title=How Does a Territory Become a State? |url=https://www.puertoricoreport.com/how-does-a-territory-become-a-state/ |access-date=November 27, 2019 |website=www.puertoricoreport.com |publisher=Puerto Rico Report}}</ref>

==Secession from the Union==
{{Main|Secession in the United States}}

The Constitution speaks of "union" several times, but does not explicitly discuss the issue of whether a state can [[secede]] from the Union. Its predecessor, the [[Articles of Confederation]], stated that the union of the United States "shall be [[Perpetual Union|perpetual]]." The question of whether or not individual states held the unilateral right to secession was a passionately debated feature of the nations' political discourse from early in its history and remained a difficult and divisive topic until the [[American Civil War]]. In 1860 and 1861, 11 southern states each declared secession from the United States and joined to form the [[Confederate States of America]] (CSA). Following the defeat of Confederate forces by Union armies in 1865, those states were brought back into the Union during the ensuing [[Reconstruction era]]. The federal government never recognized the sovereignty of the CSA, nor the validity of the [[ordinances of secession]] adopted by the seceding states.<ref name=PavkovićRadan/><ref name="74700TvW">{{Cite web |title=Texas v. White |url=https://www.law.cornell.edu/supremecourt/text/74/700 |url-status=live |archive-url=https://web.archive.org/web/20180313024759/https://www.law.cornell.edu/supremecourt/text/74/700 |archive-date=March 13, 2018 |access-date=March 14, 2018 |publisher=Legal Information Institute |location=Cornell Law School, Ithaca, New York |df=mdy-all}}</ref>

Following the war, the United States Supreme Court, in ''[[Texas v. White]]'' (1869), held that states did not have the right to secede and that any act of secession was legally void. Drawing on the "[[Perpetual Union|perpetual]]" union language of the Articles of Confederation, and its succeeding [[Preamble to the United States Constitution|Preamble to the Constitution]], which states that the Constitution intends to "form a more perfect union", and speaks of the people of the United States a single body politic who are the authors of the more perfect union ("We the people"), the Supreme Court found that states did not have a right to secede. The court's reference in the same decision to the possibility of such changes occurring "through revolution, or through consent of the States", essentially means that this decision holds that no state has a right to unilaterally decide to leave the Union.<ref name=PavkovićRadan/><ref name=74700TvW/>

==Name origins==
{{Further|List of state and territory name etymologies of the United States}}
[[File:US State Name Etymologies4.png|thumb|upright=1.25|A map showing the source languages of state names]]

The 50 states have taken their names from a wide variety of languages. Twenty-four state names originate from [[Indigenous languages of the Americas|Native American languages]]. Of these, eight are from [[Algonquian languages]], seven are from [[Siouan languages]], three are from [[Iroquoian languages]], one is from [[Uto-Aztecan languages]] and five others are from other indigenous languages. [[Hawaii]]'s name is derived from the Polynesian [[Hawaiian language]].

Of the remaining names, 22 are from European languages. Seven are from [[Latin]] (mainly [[Latinisation (literature)|Latinized]] forms of English names) and the rest are from English, Spanish and French. Eleven states are [[Eponym|named after individual people]], including seven named for royalty and one named after a [[President of the United States]]. The origins of six state names are unknown or disputed. Several of the states that derive their names from [[ethnonym|names used for Native peoples]] retain the final letter "s" in the indigenous name.

==Geography==
{{main|Geography of the United States}}

===Borders===
The borders of the 13 original states were largely determined by [[British colonization of the Americas|colonial charters]]. Their western boundaries were subsequently modified as the states ceded their western land claims to the Federal government during the 1780s and 1790s. Many state borders beyond those of the original 13 were set by Congress as it created territories, divided them, and over time, created states within them. Territorial and new state lines often followed various geographic features (such as [[List of river borders of U.S. states|rivers]] or mountain range peaks), and were influenced by settlement or transportation patterns. At various times, national borders with territories formerly controlled by other countries ([[British North America]], [[New France]], [[New Spain]] including [[Spanish Florida]], and [[Russian America]]) became institutionalized as the borders of U.S. states. In the West, relatively arbitrary lines following latitude and longitude often prevail due to the sparseness of settlement west of the Mississippi River.

Once established, most state borders have, with few exceptions, been generally stable. Only two states, Missouri ([[Platte Purchase]]) and Nevada grew appreciably after statehood. Several of the original states [[State cessions|ceded land]], over a several-year period, to the Federal government, which in turn became the Northwest Territory, [[Southwest Territory]], and [[Mississippi Territory]]. In 1791, Maryland and Virginia ceded land to create the [[District of Columbia]] (Virginia's portion was [[District of Columbia retrocession|returned]] in 1847). In 1850, Texas ceded a large swath of land to the federal government. Additionally, Massachusetts and Virginia (on two occasions), have lost land, in each instance to form a new state.

There have been numerous other minor adjustments to state boundaries over the years due to improved surveys, resolution of ambiguous or disputed boundary definitions, or minor mutually agreed boundary adjustments for administrative convenience or other purposes.<ref name="StatesShapes">{{Cite book |last=Stein |first=Mark |title=How the States Got Their Shapes |publisher=HarperCollins |year=2008 |isbn=9780061431395 |location=New York |pages=xvi, 334}}</ref> Occasionally, either Congress or the U.S. Supreme Court has had to settle state border disputes. One notable example is the case ''[[New Jersey v. New York]]'', in which [[New Jersey]] won roughly 90% of [[Ellis Island]] from [[New York (state)|New York]] in 1998.<ref>{{Cite news |last=Greenhouse |first=Linda |date=May 27, 1998 |title=The Ellis Island Verdict: The Ruling; High Court Gives New Jersey Most of Ellis Island |url=https://www.nytimes.com/1998/05/27/nyregion/ellis-island-verdict-ruling-high-court-gives-new-jersey-most-ellis-island.html?pagewanted=all&src=pm |url-status=live |archive-url=https://web.archive.org/web/20121115211230/http://www.nytimes.com/1998/05/27/nyregion/ellis-island-verdict-ruling-high-court-gives-new-jersey-most-ellis-island.html?pagewanted=all&src=pm |archive-date=November 15, 2012 |access-date=August 2, 2012 |work=[[The New York Times]] |df=mdy-all}}</ref>

Once a [[Territories of the United States|territory]] is admitted by Congress as a state of the Union, the state must consent to any changes pertaining to the jurisdiction of that state and Congress.<ref>Article IV, Section 3, Constitution of the United States</ref> The only potential violation of this occurred when the legislature of [[Virginia]] declared the [[Confederate States of America|secession of Virginia]] from the United States at the start of the [[American Civil War]] and a newly formed alternative Virginia legislature, recognized by the federal government, consented to have [[West Virginia]] secede from Virginia.

===Regional grouping===
{{Further|List of regions of the United States}}

States may be grouped in regions; there are many variations and possible groupings. Many are defined in law or regulations by the federal government. For example, the United States Census Bureau defines four statistical regions, with nine divisions.<ref>{{Cite web |last=United States Census Bureau, Geography Division |title=Census Regions and Divisions of the United States |url=http://www2.census.gov/geo/pdfs/maps-data/maps/reference/us_regdiv.pdf |url-status=live |archive-url=https://web.archive.org/web/20160304125032/http://www2.census.gov/geo/pdfs/maps-data/maps/reference/us_regdiv.pdf |archive-date=March 4, 2016 |access-date=January 10, 2013}}</ref> The Census Bureau region definition ([[Northeastern United States|Northeast]], [[Midwest]], [[Southern United States|South]], and [[Western United States|West]]) is "widely used ... for data collection and analysis,"<ref name="NEMS">"The National Energy Modeling System: An Overview 2003" (Report #:DOE/EIA-0581, October 2009).
