Article VI: Federal Supremacy, Debts & Constitutional Oaths
Constitutional text excerpts, statutory breakdowns, and comprehensive legal analysis.
Executive Constitutional Summary
Article VI establishes three important constitutional principles. First, it recognizes the continuing validity of debts and other engagements incurred by the United States under the Articles of Confederation before the new Constitution was adopted. Second, the Supremacy Clause establishes the Constitution, federal laws made in pursuance of the Constitution, and treaties made under federal authority as the supreme Law of the Land, with state judges bound by those rules notwithstanding conflicting state law. Third, Article VI requires federal and state legislators, executives, and judges to take an oath or affirmation supporting the Constitution and expressly prohibits religious tests as qualifications for federal office or public trust.
Constitutional Text Excerpt
"All Debts contracted and Engagements entered into, before the Adoption of this Constitution, shall be as valid against the United States under this Constitution, as under the Confederation. This Constitution, and the Laws of the United States which shall be made in Pursuance thereof; and all Treaties made, or which shall be made, under the Authority of the United States, shall be the supreme Law of the Land; and the Judges in every State shall be bound thereby, any Thing in the Constitution or Laws of any State to the Contrary notwithstanding. The Senators and Representatives before mentioned, and the Members of the several State Legislatures, and all executive and judicial Officers, both of the United States and of the several States, shall be bound by Oath or Affirmation, to support this Constitution; but no religious Test shall ever be required as a Qualification to any Office or public Trust under the United States."

Simplified Explanation & Constitutional Framework
Article VI helps establish the constitutional hierarchy that allows the federal system to operate as one Union. Its first clause prevents the change from the Articles of Confederation to the Constitution from invalidating preexisting national debts and engagements. Its second clause, commonly called the Supremacy Clause, establishes a hierarchy in which the Constitution is supreme and valid federal laws and treaties made under federal authority take precedence over conflicting state law. The Supremacy Clause does not mean that every federal enactment or treaty automatically overrides every state rule; federal law must itself be constitutionally valid, and the scope of preemption depends on constitutional text, federal statutes, treaties, congressional intent, and Supreme Court doctrine. The third clause establishes an oath or affirmation requirement for specified federal and state officeholders and prohibits religious tests for offices and public trusts under the United States. Together, these provisions reinforce constitutional supremacy, continuity of national obligations, and a secular qualification standard for federal office.
Core Constitutional Principles
Continuity of National Obligations
Article VI provides that debts and engagements incurred before adoption of the Constitution remain valid against the United States under the new constitutional government just as they were under the Confederation.
Constitutional Supremacy
The Constitution is the highest form of domestic law. Federal statutes and treaties receive supreme-law status when they are made under the constitutional authority of the United States.
Federal Preemption
When valid federal law conflicts with state law, federal law can displace the state rule under the Supremacy Clause. The particular result depends on constitutional and statutory preemption principles rather than on a blanket rule that all federal law automatically invalidates all state regulation.
State Judges Must Follow Federal Supremacy
Article VI expressly requires judges in every state to be bound by the Constitution, valid federal laws made in pursuance of it, and treaties made under U.S. authority even when state constitutions or statutes point in a different direction.
Constitutional Oaths
Members of Congress, state legislators, and federal and state executive and judicial officers are bound by oath or affirmation to support the Constitution.
No Federal Religious Test
Article VI prohibits requiring a religious test as a qualification for any federal office or public trust under the United States.
The Three Constitutional Clauses of Article VI
Debts and Engagements Clause
The first clause provides that debts and engagements contracted before adoption of the Constitution remain valid against the United States under the new Constitution as they were under the Articles of Confederation.
The provision assured creditors and other parties that the creation of the new constitutional government would not erase the obligations of the United States inherited from the Confederation period.
The clause is principally a continuity provision. It carries preexisting national obligations forward into the constitutional system rather than creating a new general borrowing power.
The Constitution replaced the Articles of Confederation with a stronger federal structure. Article VI made clear that the governmental transition did not nullify debts and engagements undertaken by the prior national government.
The clause is historically important because it supported continuity and confidence in the new federal government. Modern federal borrowing and fiscal authority primarily rest on other constitutional provisions, especially Article I, Section 8.
Supremacy Clause
The Supremacy Clause provides that the Constitution, federal laws made in pursuance of the Constitution, and treaties made under the authority of the United States are the supreme Law of the Land. State judges must be bound by those rules notwithstanding conflicting state constitutional or statutory provisions.
The Constitution occupies the highest position in the federal constitutional hierarchy. Federal statutes and treaties receive supremacy only within the constitutional framework governing their validity and authority.
Article VI does not declare every federal law supreme merely because Congress enacted it. The text qualifies federal laws by referring to laws made "in Pursuance" of the Constitution, reflecting the principle that federal governmental power must be constitutionally authorized.
Treaties made under the authority of the United States are included in the Supremacy Clause. Their operation within U.S. law is subject to the Constitution and the constitutional and statutory framework governing treaties.
State judges are expressly bound by the federal Constitution, valid federal laws made in pursuance of it, and treaties made under U.S. authority, even if state law says otherwise.
When an applicable and constitutionally valid federal rule conflicts with state law, the federal rule can prevail under the Supremacy Clause. This principle is commonly described as federal preemption.
Federal preemption can arise in different forms, including express preemption where Congress explicitly displaces state law, conflict preemption where compliance with both state and federal law is impossible or state law stands as an obstacle to federal objectives, and field preemption in circumstances where federal regulation is understood to occupy an entire regulatory field.
The Supremacy Clause does not mean that every federal policy preference automatically invalidates state law. Courts must first determine whether Congress or the Constitution validly occupies or preempts the relevant subject.
The Clause establishes federal supremacy within the constitutional system while leaving substantial areas of regulatory authority to the states. Federalism therefore continues even though valid federal law takes priority over conflicting state law.
Oaths, Affirmations, and Religious Test Prohibition
Clause 3 requires specified federal and state officeholders to be bound by oath or affirmation to support the Constitution. It then expressly prohibits a religious test as a qualification for any federal office or public trust.
The constitutional text covers Senators and Representatives, members of state legislatures, and all executive and judicial officers of both the United States and the states.
The Constitution allows an officeholder to make an oath or an affirmation. The requirement is therefore not limited to persons whose religious beliefs permit or require a traditional oath.
The oath or affirmation requirement creates a formal constitutional commitment by public officials to support the Constitution rather than placing loyalty solely in a particular government official, political party, or state institution.
Article VI provides that no religious Test may ever be required as a qualification for any Office or public Trust under the United States.
The Religious Test Clause was significant in rejecting the use of religious qualifications for federal public office. Colonial and European governments had historically used religious tests as conditions of eligibility for public office.
The express prohibition applies to qualifications for federal office or public trust under the United States. The Fourteenth Amendment and later constitutional doctrine have substantially changed the relationship between the federal Constitution and state requirements as well.
The Religious Test Clause and the First Amendment serve related but distinct constitutional purposes. Article VI prohibits religious qualifications for federal office, while the First Amendment separately restricts governmental establishment of religion and protects free exercise of religion.
Supremacy Clause Legal Framework
Constitutional Supremacy
The Constitution is supreme because all governmental authority ultimately operates under it. Federal and state officials are bound by constitutional requirements.
Valid Federal Statutes
Federal statutes that are constitutionally authorized can take priority over inconsistent state law.
Federal Treaties
Treaties made under U.S. authority are included within the federal supremacy framework, subject to the Constitution and the treaty-making provisions elsewhere in the constitutional system.
State Constitutions Subordinate
Article VI expressly states that federal supremacy applies notwithstanding anything in a state constitution or state law to the contrary.
State Judicial Duty
State judges must apply supreme federal law when deciding cases within their jurisdiction.
Federal Preemption Doctrine & Categories
Federal preemption is the displacement of state law by controlling federal law. It derives from the Supremacy Clause and may occur when federal law and state law conflict or when Congress has otherwise constitutionally displaced state regulation.
Congress can expressly state that federal law displaces specified state laws or regulations.
Conflict preemption can arise when it is impossible to comply with both federal and state requirements or when state law creates an obstacle to the accomplishment of federal objectives.
Field preemption can arise when federal regulation is sufficiently comprehensive that courts determine Congress intended to occupy an entire regulatory field.
Supreme Court doctrine has recognized that preemption analysis can differ depending on the statutory text, congressional intent, the federal interest involved, and the traditional state role in the subject being regulated.
A state law is not preempted merely because it differs from a federal rule. A court generally must identify a valid constitutional or statutory basis for federal displacement.
Federal-State Constitutional Relationship
States retain substantial legislative and regulatory authority over matters not displaced by federal constitutional authority or valid federal law.
When valid federal law and state law cannot operate consistently, the federal rule takes priority under the Supremacy Clause.
State courts cannot disregard controlling federal constitutional provisions, valid federal statutes, or applicable treaties merely because state law conflicts with them.
Federal supremacy assumes the federal rule is constitutionally valid. Article VI does not authorize Congress to exercise powers the Constitution does not give it.
Article VI establishes federal priority where federal authority validly operates, but it does not eliminate the constitutional division of powers between the United States and the states.
Constitutional Oaths & Affirmations
No Religious Test Prohibition
Structural Connections Across the Constitution
Congress receives important legislative and fiscal powers under Article I. Federal laws enacted under those valid powers can receive supremacy under Article VI.
The President participates in the creation and enforcement of federal law and in the treaty-making process that can produce rules covered by Article VI.
Federal courts interpret and apply the Constitution, federal laws, and treaties, while Article VI specifically binds state judges to supreme federal law.
The Tenth Amendment reserves powers not delegated to the United States or prohibited to the states. Article VI’s supremacy principle applies when valid federal authority exists, while the Tenth Amendment helps identify the boundary of that authority.
The First Amendment’s Religion Clauses complement Article VI’s ban on religious tests for federal office.
The Fourteenth Amendment imposes significant constitutional restrictions directly on states, adding another layer to the federal-state constitutional relationship described in Article VI.
Foundational Historical Context & Milestones
Articles of Confederation
The first clause of Article VI expressly continued preexisting debts and engagements from the Confederation period into the constitutional government.
Weakness of the Confederation
The Supremacy Clause helped establish a stronger national constitutional structure than the Articles of Confederation by making valid federal law superior to conflicting state law.
Religious Qualifications
The prohibition on religious tests represented a significant departure from historical systems in which religious affiliation or profession could be required for public office.

Why Article VI Matters Today
Article VI provides a foundation for the Constitution’s national legal order. Without a rule establishing the priority of the Constitution and valid federal law, conflicting state rules could undermine nationally authorized federal action. The article also ensures continuity of national financial obligations during the transition from the Articles of Confederation to the Constitution and requires public officials at both the federal and state levels to support the constitutional system. Its religious-test prohibition also establishes an important principle that federal public office cannot constitutionally be conditioned on a required religious belief or profession. Article VI therefore connects federal supremacy, federalism, continuity of government, and constitutional qualifications in a single provision.
