A U.S. territory becomes a state by moving through four steps: residents ask Congress for statehood, Congress passes an enabling act authorizing a constitutional convention, the territory drafts and ratifies a state constitution, and Congress then passes an act of admission that the president signs and announces by proclamation. That is how most of the 37 states added since the original thirteen joined the Union, and it is the answer to how does a state become a state under current practice. The Constitution does not lock in every detail of the sequence, which is why some states have taken very different routes, but the four-step path is the recognizable norm.
Where the Power to Admit States Comes From
Article IV, Section 3 of the Constitution says “New States may be admitted by the Congress into this Union.”1Library of Congress. Constitution Annotated Article IV Section 3 That single sentence gives Congress broad discretion over when a territory becomes a state and on what terms.
The same section sets two limits. A new state cannot be carved out of an existing state, and states cannot be merged or partly merged, unless the affected state legislatures and Congress all consent.2Legal Information Institute. Overview of Admissions (New States) Clause Elsewhere, Article IV requires the federal government to guarantee every state a republican form of government, so Congress reviews a proposed state constitution to confirm it establishes government through elected representatives.3Library of Congress. Constitution Annotated Article IV Section 4
Step One: Residents Petition Congress
The process starts with the territory itself. Residents signal that they want statehood, usually through a referendum or a petition to Congress. There is no constitutional requirement to hit a specific population number, but the Northwest Ordinance of 1787 set a benchmark of 60,000 free inhabitants before territories in the Northwest could apply, and that figure influenced expectations well beyond its original scope.4U.S. National Archives. Northwest Ordinance (1787)
Congress is not obligated to respond. A territory can meet every informal benchmark and still wait years, or decades, if there is no political will to move a bill forward.
Step Two: Congress Passes an Enabling Act
When Congress decides a territory is ready, it passes an enabling act. This is the legislation that authorizes residents to hold a constitutional convention and organize a state government. An enabling act generally spells out the state’s proposed boundaries, sets conditions the new constitution must meet, and lays out a timeline for the convention.
Indiana’s 1816 enabling act authorized residents to “form for themselves a constitution and state government” and specified when and where convention delegates would meet.5IN.gov. The Enabling Act 1816 The 1889 enabling act handled four territories at once, letting North Dakota, South Dakota, Montana, and Washington draft constitutions on parallel tracks.6U.S. Senate. Enabling Act of 1889
Step Three: The Territory Drafts and Ratifies a Constitution
After the enabling act passes, the territory elects delegates to a constitutional convention. Those delegates draft a proposed state constitution, and the territory’s voters then approve or reject it. Congress wants evidence that the people themselves, not only convention delegates, back the framework for the new government.
The cycle can move quickly. For the Dakota territories in 1889, the enabling act passed in February and ratification elections took place by October, about seven months later.
Step Four: Congress Admits the State and the President Proclaims It
The ratified constitution goes back to Congress for review. If both chambers approve, they pass a joint resolution or act of admission by simple majority. The president signs the resolution and issues a proclamation declaring the new state part of the Union. Hawaii’s enabling act, for example, said the state “shall be deemed admitted into the Union” when the president proclaimed the results of the required elections.7Department of the Interior. An Act to Provide for the Admission of the State of Hawaii into the Union Hawaii’s admission in 1959 was the most recent.
The presidential role is narrower than the congressional one, but it is not purely ceremonial. The veto power under Article I, Section 7 applies to a statehood bill like any other, and Congress would need a two-thirds vote in both chambers to override.8The American Presidency Project. Presidential Vetoes Presidents have also used informal pressure. Lincoln conditioned his signature on West Virginia’s admission bill on the state’s constitution including a provision to gradually abolish slavery.
What Congress Actually Weighs
The Constitution does not list qualifications for statehood, so Congress evaluates each case on its own. Several factors show up consistently:
- Population large enough to sustain a state government and justify congressional representation. The 60,000-person benchmark from the Northwest Ordinance served as a historical floor.4U.S. National Archives. Northwest Ordinance (1787)
- Economic viability, meaning the proposed state can fund its own operations.
- A republican form of government in the proposed constitution, consistent with the guarantee clause.3Library of Congress. Constitution Annotated Article IV Section 4
- Clear evidence residents want statehood, usually a referendum result.
Politics matters as much as any of these formal factors. Statehood decisions have historically turned on debates over slavery, partisan balance in the Senate, and regional power. Admission of free and slave states in pairs during the antebellum period is the clearest example. The dynamic has not disappeared; it just wears different clothes now.
Some States Skipped the Standard Path
The four-step process is the norm, not a rule. Six states joined the Union without ever being organized as federal territories: Vermont, Kentucky, Maine, Texas, California, and West Virginia.9Congress.gov. Admission of States to the Union: A Historical Reference Guide Texas came in through a joint resolution of annexation in 1845 after an annexation treaty failed in the Senate, entering as the 28th state on December 29 of that year without a territorial phase.10Texas State Library and Archives Commission. Annexation Process: 1836-1845 A Summary Timeline West Virginia was created from Virginia’s western counties in 1863 after a pro-Union “Restored Government” of Virginia consented to the split during the Civil War, and the Supreme Court later inferred Congress’s consent from the admission legislation itself.11Library of Congress. Virginia v. West Virginia, 78 U.S. 39 (1871) These are exceptions, not templates, but they show how much flexibility Congress has when it decides to use it.
What Changes on the Day of Admission
A new state enters the Union with the same constitutional powers and sovereignty as every existing state. The Supreme Court has held that “every new state is entitled to exercise all the powers of government which belong to the original states of the Union.” This equal footing doctrine limits what Congress can demand as a price of admission. It can attach conditions in an enabling act that would be valid federal legislation regardless of statehood, such as land-rights protections or civil-liberties guarantees, but it cannot extract concessions that leave the new state permanently weaker than its peers.12Legal Information Institute. U.S. Constitution Annotated Article IV Section 3 Clause 1 – Equal Footing Doctrine
Territories Seeking Admission Today
No state has been admitted since Hawaii, but two active movements are working through some version of the process now.
In Puerto Rico’s 2020 plebiscite, 52.5% of voters favored immediate admission as a state.13Congress.gov. Political Status of Puerto Rico: Brief Background and Recent Developments Statehood bills have been filed repeatedly, but none has passed both chambers. The island has roughly 3.2 million U.S. citizens who cannot vote in presidential elections and are represented in the House only by a non-voting delegate.
Washington, D.C. residents voted 86% in favor of statehood in 2016. The House passed the Washington, D.C. Admission Act (H.R. 51) in 2020 and again in 2021, the first times either chamber had approved D.C. statehood legislation, though the Senate did not act on it either time. The bill would shrink the federal district to a small area around the Capitol, White House, and National Mall, converting the residential areas into a new state. Opponents cite Article I, Section 8, which establishes a federal district; proponents point out that Congress already resized the district once, returning land to Virginia in 1846.
Both cases run into the same underlying reality: statehood is a political decision, and no referendum result or population figure forces Congress to act. New senators and House members carry partisan consequences, and those consequences drive the debate more than any constitutional checklist.
