Governments
Under U.S. constitutional law, the 50 individual states and the United States as a whole are each sovereign jurisdictions.[ Radan, 2007, p. 12] The states are ''not'' administrative divisions of the country; the Tenth Amendment to the United States Constitution
The Tenth Amendment (Amendment X) to the United States Constitution
The Constitution of the United States is the supreme law of the United States of America. This founding document, originally comprising seven articles, delineates th ...
allows states to exercise 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. A state, unlike the federal government, has un-enumerated police power, that is the right to generally make all necessary laws for the welfare of its people. 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. Many of these documents are more detailed and more elaborate than their federal counterpart. The Constitution of Alabama
The Constitution of the State of Alabama is the basic governing document of the U.S. state of Alabama. It was adopted in 1901 and is Alabama's sixth constitution.

'', 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. 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

indirectly elect the President of the United States, president and Vice President of the United States, vice president. When casting ballots in United States presidential election, presidential elections they are voting for Electoral College (United States), presidential electors, who then, using procedures provided in the Twelfth Amendment to the United States Constitution, 12th amendment, elect the president and vice president. There were 538 electors for the most recent presidential election in 2020 United States presidential election, 2020; the allocation of electoral votes was based on the 2010 United States Census, 2010 census. Each state is entitled to a number of electors equal to the total number of representatives and senators from that state; the District of Columbia is entitled to three electors.
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. All elections—federal, state, and local—are administered by the individual states, and some voting rules and procedures may differ among them.
Article Five of the United States Constitution, Article V of the Constitution accords states a key role in the process of amending the U.S. Constitution. Amendments may be proposed either by Congress with a supermajority, two-thirds vote in both the House and the Senate, or by a Convention to propose amendments to the United States Constitution, constitutional convention called for by two-thirds of the state legislatures. To become part of the Constitution, an amendment must be ratified by either—as determined by Congress—the legislatures of three-quarters of the states or state ratifying conventions in three-quarters of the states. The vote in each state (to either ratify or reject a proposed amendment) carries equal weight, regardless of a state's population or length of time in the Union.
With other countries
U.S. states are not sovereign in the Westphalian sovereignty, Westphalian sense in international law which says that each State has sovereignty over its territory and domestic affairs, to the exclusion of all external powers, on the principle of non-interference in another State's domestic affairs, and that each State (no matter how large or small) is equal in international law. Additionally, the 50 U.S. states do not possess international legal sovereignty, meaning that they are not recognized by other sovereign States such as, for example, France, Germany or the United Kingdom.[ The federal government is responsible for international relations, but state and local government leaders do occasionally travel to other countries and form economic and cultural relationships.

Admission into the Union
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.[ 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,[ 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. 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 towards 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. Three were set off from an already existing state, two entered the Union after having been sovereign states, and one was established from Territories of the United States#Formerly unorganized territories, unorganized territory:
* California, 1850, from land Mexican Cession, ceded to the United States by Mexico in 1848 under the terms of the Treaty of Guadalupe Hidalgo.][

. 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. 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. 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. West Virginia's bid for statehood was also delayed over slavery and was settled when it agreed to adopt a gradual abolition plan.
Possible new states
Puerto Rico
Puerto Rico, an Unincorporated territories of the United States, unincorporated U.S. territory, refers to itself as the "Commonwealth (U.S. insular area), Commonwealth of Puerto Rico" in the English version of its Constitution of Puerto Rico, constitution, and as "Estado Libre Asociado" (literally, Associated Free State) in the Spanish version. 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.
A non-binding referendum on statehood, independence, or a new option for an associated territory (different from the current status) was held on November 6, 2012. Sixty one percent (61%) of voters chose the statehood option, while one third of the ballots were submitted blank.
On December 11, 2012, the Legislative Assembly of Puerto Rico enacted a concurrent resolution requesting the President of the United States, President and the Congress of the United States to respond to the referendum of the people of Puerto Rico, held on November 6, 2012, to end its current form of territorial status and to begin the process to admit Puerto Rico as a state.
Another Puerto Rican status referendum, 2017, status referendum was held on June 11, 2017, in which 97% percent of voters chose statehood. Turnout was low, as only 23% of voters went to the polls, with advocates of both continued territorial status and independence urging voters to boycott it.
On June 27, 2018, the H.R. 6246 Act was introduced on the U.S. House with the purpose of responding to, and comply with, the democratic will of the United States citizens residing in Puerto Rico as expressed in the plebiscites held on November 6, 2012, and June 11, 2017, by setting forth the terms for the admission of the territory of Puerto Rico as a state of the Union. The act has 37 original cosponsors between Republicans and Democrats in the U.S. House of Representatives.
On November 3, 2020, Puerto Rico held another 2020 Puerto Rican status referendum, referendum. In the non-binding referendum, Puerto Ricans voted in favor of becoming a state. They also voted for a pro-statehood Governor of Puerto Rico, governor, Pedro Pierluisi.
Washington, D.C.
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. For statehood to be achieved, it must be approved by Congress.
Others
Other possible new states are Guam and the U.S. Virgin Islands, both of which are Territories of the United States#Incorporated and unincorporated territories, unincorporated organized territories of the United States. Also, the Commonwealth of the Northern Mariana Islands, and American Samoa, an unorganized, unincorporated territory, could seek statehood.

from the Union. Its predecessor, the Articles of Confederation
The Articles of Confederation and Perpetual Union was an agreement among the 13 original states of the United States of America
The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America ...
, stated that 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.
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 Preamble to the United States Constitution, Preamble to the Constitution, which states that the Constitution was intended to "form a more perfect union" and speaks of the people of the United States in effect as a single body politic, as well as the language of the Articles of Confederation, the Supreme Court maintained that states did not have a right to secede. However, 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.[

Origins of states' 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 languages, 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 have retained the plural ending of "s".
Geography
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 straight 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. 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.
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. 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
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. 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,"["The National Energy Modeling System: An Overview 2003" (Report #:DOE/EIA-0581, October 2009). United States Department of Energy, Energy Information Administration.] and is the most commonly used classification system.["(M)ost demographic and food consumption data are presented in this four-region format."
