Geography

Borders

The borders of the 13 original states were largely determined by 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 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 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 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.^[30] Occasionally the United States Congress or the United States Supreme Court have settled 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 in 1998.^[48]

Regional grouping

Further information: List of regions of the United States

States may be grouped in regions; there are endless 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.^[49] The Census Bureau region definition is "widely used … for data collection and analysis,"^[50] and is the most commonly used classification system.^[51][52][53] Other multi-state regions are unofficial, and defined by geography or cultural affinity rather than by state lines.

Origins of states' names

The 50 states have taken their names from a wide variety of languages. Twenty-four state names originate from 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 from Latin (mainly Latinized forms of English names), the rest are from English, Spanish and French. Eleven states are named after individual people, including seven named for royalty and one named after an American president. The origins of six state names are unknown or disputed. Several of the states that derive their names from (corrupted) names used for Native peoples, have retained the plural ending of "s".

Commonwealths

Main article: Commonwealth (U.S. state)

Four states – Kentucky, Massachusetts, Pennsylvania, and Virginia – adopted constitutions early in their post-colonial existence identifying themselves as commonwealths, rather than states. These commonwealths are states, but legally, each is a commonwealth because the term is contained in its constitution.^[46] As a result, "commonwealth" is used in all public and other state writings, actions or activities within their bounds.
The term, which refers to a state in which the supreme power is vested in the people, was first used in Virginia during the Interregnum, the 1649–60 period between the reigns of Charles I and Charles II during which parliament's Oliver Cromwell as Lord Protector established a 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. When Virginia adopted its first constitution on June 29, 1776, it was reintroduced.^[47] Pennsylvania followed suit when it drew up a constitution later that year, as did Massachusetts, in 1780, and Kentucky, in 1792.^[46]
The U.S. territories of the Northern Marianas and Puerto Rico are also referred to as commonwealths. This designation does have a legal status different from that of the 50 states. Both of these commonwealths are unincorporated territories of the United States.

Secession from the Union

Main article: Secession in the United States

The Constitution is silent on the issue of the secession of a state from the union. However, its predecessor document, the Articles of Confederation, stated that the United States "shall be perpetual." The question of whether or not individual states held the right to unilateral secession remained a difficult and divisive one until the American Civil War. In 1860 and 1861, eleven southern states seceded, but following their defeat in the American Civil War were brought back into the Union during the Reconstruction Era. The federal government never recognized the secession of any of the rebellious states.^[8][45]
Following the Civil War, the United States Supreme Court, in Texas v. White, 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 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.^[8][45]

Possible new states

Puerto Rico

Main articles: Political status of Puerto Rico and Proposed political status for Puerto Rico

Puerto Rico referred to itself as the "Commonwealth of Puerto Rico" in the English version of its constitution, and as "Estado Libre Asociado" (literally, Associated Free State) in the Spanish version.
As with any non-state territory of the United States, its residents do not have voting representation in the federal government. Puerto Rico has limited representation in the U.S. Congress in the form of a Resident Commissioner, a delegate with limited voting rights in the Committee of the Whole House on the State of the Union, and no voting rights otherwise.^[39]
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.^[40][41]
On December 11, 2012, the Legislative Assembly of Puerto Rico enacted a concurrent resolution requesting the 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.^[42]

Washington, D.C.

Main article: District of Columbia statehood movement

The intention of the 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. The inhabitants of the District do not have full representation in Congress or a sovereign elected government (they were allotted presidential electors by the 23rd amendment, and have a non-voting delegate in Congress).
Some 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.

Others

Various proposals to divide California, usually involving splitting the southern half from the north or the urban coastline from the rest of the state, have been advanced since the 1850s.^[43] Similarly, numerous proposals to divide New York, all of which involve to some degree the separation of New York City from the rest of the state, have been promoted over the past several decades.^[44]
Other possible new states are Guam and the Virgin Islands, both of which are unincorporated organized territories of the United States. Also, either the Northern Mariana Islands or American Samoa, an unorganized, unincorporated territory, could seek statehood.

The order in which the original 13 states ratified the constitution, then the order in which the others were admitted to the union. (Click to see animation)

Article IV, Section 3, Clause 1 of the U.S. Constitution 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 the original 13 to 50. Each new state has been admitted on an equal footing with the existing states.^[19] It 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 Western land claims (including Georgia, North Carolina, and Virginia), to have a veto over whether their western counties could become states,^[18] and has served this same function since, whenever a 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 have been created from organized territories established and governed by Congress in accord with its plenary power under Article IV, Section 3, Clause 2.^[29] 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 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 upon 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 unorganized territory:

• California, 1850, from land ceded to the United States by Mexico in 1848 under the terms of the Treaty of Guadalupe Hidalgo.^[30][31][32]
• Kentucky, 1792, from Virginia (District of Kentucky: Fayette, Jefferson, and Lincoln counties)^[30][31][33]
• Maine, 1820, from Massachusetts (District of Maine)^[30][31][33]
• Texas, 1845, previously the Republic of Texas^[30][31][34]
• Vermont, 1791, previously the Vermont Republic (also known as the New Hampshire Grants and claimed by New York)^[30][31][35]
• West Virginia, 1863, from Virginia (Trans-Allegheny region counties) during the Civil War^[31][33][36]

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 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 Sequoyah in 1905, as a means to retain control of their lands.^[37] The proposed constitution ultimately failed in the U.S. Congress. Instead, the Indian Territory, along with 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 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 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.^[38] Also, statehood for Kansas Territory was held up for several years (1854–61) due to a series of internal violent conflicts involving anti-slavery and pro-slavery factions.

Relationships

Among states

Each state admitted to the Union by Congress since 1789 has entered it on an equal footing with the original States in all respects.^[18] With the growth of states' rights advocacy during the antebellum period, the Supreme Court asserted, in Lessee of Pollard v. Hagan (1845), that the Constitution mandated admission of new states on the basis of equality.^[19] With the consent of Congress, states may enter into interstate compacts, agreements between two or more states. Compacts are frequently used to manage a shared resource, such as transportation infrastructure or water rights.^[20]
Under Article Four of the United States Constitution, which outlines the relationship between the states, each state is required to give 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. Under the Extradition Clause, a state must extradite people located there who have fled charges of "treason, felony, or other crimes" in another state if the other state so demands. The principle of hot pursuit of a presumed felon and arrest by the law officers of one state in another state are often permitted by a state.^[21]
Regardless of the Full Faith and Credit Clause, 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.^[22] 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 basic rights, under the Privileges and Immunities Clause.

With the federal government

Further information: Federalism in the United States

Every state is guaranteed^[23] a form of government that is grounded in republican principles, such as the consent of the governed.^[24] This guarantee has long been at the fore-front 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.
As with state elections, elections for the federal government are generally administered by each state, and some voting rules and procedures may differ among states.^[25] In the federal Congress, each state is guaranteed two U.S. Senators, and at least one U.S. Representative from that state. The number of U.S. Representatives is limited to 435. These representatives are elected for two-year terms and are apportioned by relative population among the states every ten years. The U.S. Electoral College elects the president every four years and the states select the electors, which for each state's delegation are equal to its number of senators and representatives.
Since the early 20th century, the Supreme Court has interpreted the Commerce Clause of the Constitution of the United States to allow greatly expanded scope of federal power over time, 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."^[26] In Wickard v. Filburn 317 U.S. 111 (1942), 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.^[27]
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. In recent years, the Court has tried to place limits on the Commerce Clause in such cases as United States v. Lopez and United States v. Morrison.^{[clarification needed]}
Another example of congressional power is its spending power – the ability of Congress to impose taxes and distribute the resulting revenue back to the states (subject to conditions set by Congress).^[28] An example of this is the system of federal aid for highways, which include the Interstate Highway System. The system is mandated and largely funded by the federal government, and also serves the interests of the states. By threatening to withhold federal highway funds, Congress has been able to pressure state legislatures to pass a variety of laws.^{[citation needed]} An example is the nationwide legal drinking age of 21, enacted by each state, brought about by the National Minimum Drinking Age Act. 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 483 U.S. 203 (1987).
