Astate of theUnited States is one of the 50constituent entities that shares itssovereignty with thefederal government.Americans arecitizens of both thefederal republic and of the state in which theyreside, due to the shared sovereignty between each state and the federal government.[1]Kentucky,Massachusetts,Pennsylvania, andVirginia use thetermcommonwealth rather thanstate in their full official names.
States are the primarysubdivisions of the United States. They possess all powers not granted to the federal government nor prohibited to them by theConstitution of the United States. In general,state governments have the power to regulate issues of local concern, such as regulating intrastate commerce, runningelections, creatinglocal governments, public school policy, and non-federal road construction and maintenance. Each state has its ownconstitution grounded inrepublican principles, andgovernment consisting ofexecutive,legislative, andjudicial branches.[2]
All states and their residents are represented in the federalCongress, abicameral legislature consisting of theSenate and theHouse of Representatives. Each state is represented by two senators, and at least one representative, while the size of a state's House delegation depends on its total population, as determined by the most recent constitutionally mandated decennialcensus.[3] Additionally, each state is entitled to select a number of electors to vote in theElectoral College, the body that elects thePresident of the United States andVice President of the United States, equal to the total of representatives and senators in Congress from that state.[4]
Article IV, Section 3, Clause 1 of the Constitution grants to Congress the authority toadmit new states into theUnion. Since the establishment of the United States in 1776, the number of states has expanded fromthe original 13 to 50. Each new state has been admitted on anequal footing with the existing states.[5]
The following table is a list of all 50 states and their respective dates of statehood. The first 13 became states in July 1776 upon agreeing to theUnited States Declaration of Independence, and each joined the first Union of states between 1777 and 1781, upon ratifying theArticles of Confederation, its first constitution.[6] (A separate table is included below showingAoC ratification dates.) These states are presented in the order in which eachratified the 1787 Constitution and joined the others in the new (and current) federal government. The date of admission listed for each subsequent state is the official date set by Act of Congress.[a]
