No, U.S. states cannot secede from the Union on their own. The Supreme Court settled the question in 1869 when it ruled that the Constitution created a permanent nation and that no state has the power to walk away from it by unilateral action. The only exits the Court left open are revolution or the collective agreement of the other states, neither of which is a legal process a state legislature can trigger by itself.
What the Constitution Says About Leaving
The Constitution contains no clause allowing a state to secede and no clause explicitly forbidding it. That silence has fueled arguments on both sides for two centuries, but it is less ambiguous than it first appears.
The Articles of Confederation, which governed the country before the Constitution, described the union as “perpetual.” Article XIII stated that “the Articles of this confederation shall be inviolably observed by every state, and the union shall be perpetual.”1National Archives. Articles of Confederation (1777) The framers replaced that document with one whose Preamble announces the goal of forming “a more perfect Union,” language that builds on the permanence already established rather than introducing an escape hatch.2Library of Congress. U.S. Constitution – The Preamble
The Constitution also creates a detailed process for admitting new states but says nothing about how one might leave. The framers argued over every clause. The absence of any exit mechanism was not an oversight.
The Tenth Amendment Argument
Secession supporters sometimes point to the Tenth Amendment, which reserves to the states, or the people, all powers not delegated to the federal government or prohibited to the states. The argument runs: because the Constitution never explicitly gave the federal government the power to prevent secession, that power belongs to the states. The Supreme Court addressed exactly this logic and rejected it. The Constitution does not need to specifically prohibit secession if the entire structure of the document creates a permanent union.
Texas v. White: The Binding Ruling
The case that turned the Civil War’s practical result into constitutional law was Texas v. White, decided in 1869. Chief Justice Salmon Chase, writing for the majority, held that Texas had never left the Union because it was legally impossible to do so. The Union, Chase wrote, predated the Constitution. It began with the Articles of Confederation’s “perpetual” commitment and was strengthened, not weakened, by the new Constitution. The relationship between a state and the Union was “indissoluble,” and the Constitution “in all its provisions, looks to an indestructible Union, composed of indestructible States.”3Justia Law. Texas v. White
The Court ruled that Texas’s secession ordinance and all the Confederate-era legislation that flowed from it were “absolutely null” and “utterly without operation in law.” Texas had never stopped being a state. Its relationship to the Union had been disrupted, not severed. The reasoning applied equally to every other state that had attempted to secede.
The opinion did leave one narrow door open. Chase acknowledged that the bond between a state and the Union could potentially be broken “through revolution, or through consent of the States.”3Justia Law. Texas v. White Neither is a unilateral state action. Revolution means overthrowing the existing order entirely. Consent of the states means the rest of the nation agreeing to let one member go.
The Fourteenth Amendment’s Guardrails
The Fourteenth Amendment, ratified in 1868 (one year before Texas v. White), added constitutional provisions that directly penalize rebellion.
Section 3 bars anyone from holding federal or state office if they previously swore an oath to support the Constitution and then “engaged in insurrection or rebellion against the same, or given aid or comfort to the enemies thereof.”4Library of Congress. Fourteenth Amendment Section 3 Only a two-thirds vote of both chambers of Congress can lift that disqualification. State officials who led or supported a secession effort would be constitutionally barred from holding office again.
Section 4 declares the public debt of the United States “shall not be questioned” and prohibits the United States or any state from paying “any debt or obligation incurred in aid of insurrection or rebellion against the United States.”5National Archives. 14th Amendment to the U.S. Constitution: Civil Rights (1868) A seceding state’s government debt would be void under federal law. The amendment was written in the shadow of the Civil War, but its text is not limited to that era.
Federal Criminal Penalties
Federal criminal law treats an actual attempt at secession as it treats any rebellion. Two statutes are directly relevant.
Under 18 U.S.C. § 2383, anyone who participates in, assists, or encourages a rebellion against the authority of the United States faces up to ten years in federal prison. Conviction also permanently disqualifies the person from holding any federal office.6Office of the Law Revision Counsel. 18 USC 2383 Rebellion or Insurrection
Seditious conspiracy under 18 U.S.C. § 2384 carries harsher consequences. If two or more people conspire to overthrow the U.S. government, oppose its authority by force, or seize federal property, each faces up to twenty years in prison.7Office of the Law Revision Counsel. 18 U.S. Code 2384 – Seditious Conspiracy State officials who organized a secession effort and ordered the seizure of federal installations would fit within the statute. The Justice Department secured seditious conspiracy convictions as recently as 2023.
The Texas Myth
A persistent claim holds that Texas has a unique, legally recognized right to secede because of the terms of its 1845 annexation. This is wrong. The 1845 congressional resolution admitting Texas included a provision allowing the state to divide itself into as many as five states in the future, with congressional approval. That language says nothing about leaving the United States. It addresses subdivision within the Union, not departure from it. The power to admit new states belongs exclusively to Congress under Article IV, Section 3.8Library of Congress. Article IV Section 3
Texas v. White itself involved Texas, and the Court could hardly have been more explicit that Texas had no right to leave. If any state had a special secession privilege, the Court would have found it there. It found the opposite.
The Two Theoretical Paths
Texas v. White acknowledged two ways a state could separate from the Union. Both require collective action, and both face enormous obstacles.
Constitutional Amendment
The most orderly route would be a constitutional amendment authorizing a state’s departure. Article V requires a proposed amendment to clear one of two hurdles: approval by two-thirds of both the House and Senate, or a call for a constitutional convention by two-thirds of state legislatures (currently 34 of 50). Either way, the amendment must then be ratified by three-fourths of the states, currently 38 of 50.9Constitution Annotated. ArtV.1 Overview of Article V, Amending the Constitution
A state wanting to leave would need 37 other states to agree to let it go. No amendment authorizing secession has ever been seriously proposed, let alone come close to passage. The convention-of-states route has never been used for any amendment in American history, and scholars still debate basic procedural questions about how such a convention would work.10Cornell Law School Legal Information Institute (LII). Proposals by Convention
Consent of the States
The other peaceful option would be a negotiated departure with the consent of Congress and the other states. No procedure for this exists anywhere in law. It would require the country to invent a process from scratch, addressing everything from the departing state’s share of the national debt to the citizenship status of its residents to the fate of federal military installations on its soil.
Revolution
Chase’s mention of “revolution” was not an invitation. It was a statement of political reality: any government can be overthrown by force, but that is by definition extralegal. Revolution does not operate within the constitutional system; it replaces it. A successful revolution would create a new nation through force, not through the exercise of a constitutional right.
What Secession Would Actually Cost Residents
Even if a state somehow navigated one of the theoretical paths, the practical consequences would be severe.
Citizenship and Federal Benefits
Residents of a state that left the Union would face an immediate question about citizenship. The Fourteenth Amendment grants citizenship to anyone “born or naturalized in the United States and subject to the jurisdiction thereof.” A territory that is no longer part of the United States arguably falls outside that jurisdiction for future births, and existing citizens might need to choose between their new country and their old one.
Social Security and Medicare would almost certainly stop for residents who stayed. The Social Security Administration defines “outside the United States” as anywhere other than the 50 states, the District of Columbia, and U.S. territories. Residents of a seceded state would meet that definition. U.S. citizens living abroad can often continue receiving Social Security payments, but Medicare coverage does not extend outside the United States at all.11Social Security Administration. Your Payments While You Are Outside the United States
Federal Property and the National Debt
The federal government owns large amounts of land within many states. In western states the figure can exceed 45 percent of the total land area, and in Nevada the federal government owns roughly 80 percent.12Congress.gov. Federal Land Ownership: Overview and Data Military bases, national parks, federal courthouses, and post offices are all federal property. A departing state would have no legal claim to any of it.
The national debt, which as of 2026 exceeds $36 trillion, adds another problem. A departing state would presumably owe some share, but no legal framework exists for calculating it. Population, GDP, and tax revenue are all possibilities. The question has no answer because nobody has ever needed to answer it. The Fourteenth Amendment’s public debt clause adds a further complication, because the departing state could not simply refuse to pay its portion without triggering a constitutional confrontation with the country it just left.
Modern Secession Movements
Despite the legal impossibility of unilateral secession, the idea never fully goes away. Polling from early 2026 found that roughly 18 percent of Americans said they would like to see their state secede from the United States. In California, about 29 percent of residents expressed support. Movements like the Texas Nationalist Movement and the California Independence Party maintain organized advocacy, though none has produced a viable legal path forward.
Support tends to shift with which party holds the White House, and history tracks the same way. Every generation since the Civil War has produced secession talk from one region or another, and none has come close to a constitutional amendment, a congressional vote, or an actual revolution. The Constitution does not allow unilateral secession, the Supreme Court has said so in the clearest possible terms, and federal criminal law punishes the attempt. The question has been legally settled since 1869.
