The Bill of Rights comprises the first ten amendments to the United States Constitution, ratified on December 15, 1791, when Virginia became the eleventh state to approve them, supplying the three-fourths majority required under Article V. James Madison drafted and introduced the amendments in the First Congress on June 8, 1789, distilling some two hundred proposals submitted by the state ratifying conventions. Congress approved twelve articles on September 25, 1789 and transmitted them to the states; only ten of these were ratified at the time. The Bill of Rights was a direct response to Anti-Federalist demands, voiced by figures such as George Mason and Patrick Henry, that the unamended 1787 Constitution dangerously lacked explicit protections against federal power — a concern that had nearly derailed ratification in Massachusetts, Virginia, and New York.
The ten amendments enumerate specific guarantees. The First Amendment protects freedoms of religion, speech, press, assembly, and petition; the Second secures the right to keep and bear arms; the Third restricts the quartering of soldiers; the Fourth bars unreasonable searches and seizures; the Fifth guarantees due process, grand-jury indictment, and protection against self-incrimination and double jeopardy; the Sixth and Seventh secure jury trial rights; the Eighth prohibits cruel and unusual punishment and excessive bail. The Ninth Amendment clarifies that the enumeration of rights does not deny others retained by the people, and the Tenth reserves undelegated powers to the states or the people, embodying federalism. As originally understood under Barron v. Baltimore (1833), these protections bound only the federal government, not the states.
Two of the twelve articles Congress proposed in 1789 were not ratified in 1791. One, governing congressional apportionment, was never adopted. The other, restricting congressional pay raises from taking effect until an intervening election, lay dormant for two centuries before being ratified as the Twenty-Seventh Amendment on May 7, 1992. The doctrine of selective incorporation, developed through the Due Process Clause of the Fourteenth Amendment (1868) in cases from Gitlow v. New York (1925) through McDonald v. Chicago (2010), progressively applied most Bill of Rights guarantees against the states, transforming their practical reach far beyond the founders' design.
For the FSOT US History section, candidates should master the precise chronology — Madison's 1789 introduction, congressional transmittal of twelve articles, and Virginia's decisive December 15, 1791 ratification — together with the Federalist–Anti-Federalist debate that produced the demand. Examiners frequently test the distinction between the twelve proposed and ten ratified amendments, the delayed Twenty-Seventh Amendment, the original federal-only scope confirmed in Barron v. Baltimore, and subsequent incorporation under the Fourteenth Amendment. Questions may also pair the Bill of Rights with The Federalist No. 84, in which Alexander Hamilton argued a bill of rights was unnecessary and even dangerous — a position the ratification ultimately overrode.
Example
In 1791, Virginia's ratification on December 15 supplied the eleventh state needed to make the Bill of Rights part of the United States Constitution.
