Last reviewed: 2026-08-28Topic: History of U.S. Gun Laws
Quick answer

The Second Amendment was ratified with the Bill of Rights in 1791. Its text connects a “well regulated Militia” with “the right of the people to keep and bear Arms,” and its legal meaning has evolved through later constitutional interpretation.

Modern gun-law litigation begins with twenty-seven words adopted at the founding, but understanding those words requires the ratification debates and later constitutional history.

Why it matters: The Second Amendment was ratified with the Bill of Rights in 1791. Its text connects a “well regulated Militia” with “the right of the people to keep and bear Arms,” and its legal meaning has evolved through later constitutional interpretation.

From English and colonial antecedents to the Bill of Rights

Constitution Annotated traces historical discussions in part to the English Bill of Rights of 1689, colonial militia practice and state ratification proposals seeking protection against disarmament and standing armies.

Madison’s proposed language

James Madison introduced an early version in the First Congress. The final text was revised before ratification as part of the Bill of Rights on December 15, 1791.

The Supreme Court did not immediately define the right

For much of U.S. history, the Supreme Court had little Second Amendment jurisprudence. Nineteenth-century cases treated the Amendment as a limit on the federal government, not the states.

Why 1791 remains central after Bruen

Modern Second Amendment doctrine looks to text and historical tradition, making founding-era sources important to contemporary litigation even though courts also examine later historical evidence.

Where this fits in the larger timeline

This event is part of the History of Gun Laws in America series. Federal firearm law developed incrementally through constitutional amendments, taxation and commerce statutes, criminal prohibitions, background-check legislation and modern Second Amendment decisions.
