What the Bill of Rights is and why December 15 matters
The Bill of Rights refers to the first ten amendments to the United States Constitution, and those ten amendments were ratified on December 15, 1791, a date now observed as bill of rights day in the United States. The National Archives preserves a transcription of the Bill of Rights that records the amendments and the ratification date, which helps fix the historical milestone in primary documents National Archives transcription.
The amendments in the Bill of Rights were proposed by the First Congress after the Constitution was adopted, when lawmakers moved to supply protections that many delegates and state ratifying conventions had requested. For researchers seeking the record of the congressional proposal and the formal texts, the Library of Congress offers primary documents that trace the legislative steps that led to the ten amendments becoming law Library of Congress primary documents.
How the ratification process worked: a step-by-step timeline
On September 25, 1789, the First Congress proposed a set of amendments to the Constitution, sending twelve proposed changes to the states for ratification. The record of the congressional proposal and the specific dates is available in early congressional records and summaries of the proposal process Congress.gov ratification records. See our first ten amendments resource.
After the proposal, each state considered the amendments according to its own procedures. Over the following months and years, states sent official ratification documents back to the federal government. Ten of the twelve proposed amendments received the necessary approvals from the states and thus became the group known as the Bill of Rights by December 15, 1791. That sequence, from proposal to the recording of sufficient ratifications, stretched across a span of about 26 months, illustrating how early amendments moved through state processes before becoming part of the constitutional record Library of Congress primary documents.
The formal timeline matters because it separates the dates of proposal from the dates of ratification, and it shows how amendments can take time to secure state consent. Scholars and teachers commonly refer to this interval as the Bill of Rights timeline 1789-1791 to emphasize that proposal and ratification were distinct steps in the constitutional process. For a state by state listing of ratification dates and the timing of approvals that led to the December 1791 conclusion, the Congress.gov compilation provides detailed entries and dates for each relevant action Congress.gov ratification records.
Understanding the mechanics is also practical. Ratification required a threshold of state approvals under Article V of the Constitution as interpreted at the time, and clerks recorded the official ratification notices. The record-keeping practices of the period are preserved in archival transcriptions and early congressional documents, which researchers use to confirm exactly when the ten amendments met the requirements to be recognized as part of the Constitution National Archives transcription.
James Madison’s role in drafting and advocating the amendments
Stay informed and get updates from Michael Carbonara
Consult the Library of Congress and National Archives transcriptions to read the drafts and debates that show how Madison framed the amendments and how Congress recorded them.
James Madison is widely credited as the principal drafter and congressional advocate for the amendments that became the Bill of Rights. For an accessible account of Madison’s work drafting proposals and pressing for amendments, Encyclopaedia Britannica provides a concise discussion of his role in the First Congress Encyclopaedia Britannica on Madison.
Madison first brought forward a list of proposed amendments in the First Congress after discussing the need for certain protections during the state ratification debates. He refined the language and argued for a set of changes that would address concerns about individual liberties and the scope of federal power. The Library of Congress collection of primary documents includes Madison’s drafts and congressional records that show how he moved the amendments through committee and floor discussion Library of Congress primary documents. For a guided collection see Bill of Rights: Primary Documents guide.
Madison’s advocacy was pragmatic. He sought amendments that would secure broader support for the new government and respond to objections raised during the constitutional ratification process. Historians often note that Madison’s role combined drafting skill with legislative work in committee and on the House floor as the proposed amendments went to the states for ratification Encyclopaedia Britannica on Madison.
The two originally unratified amendments and the later 27th Amendment
When Congress sent the twelve proposed amendments to the states in 1789, two did not receive sufficient ratifications by December 1791. The ten that were ratified became the Bill of Rights, while two remained outstanding because they lacked the necessary state approvals at that time. For a concise record of which proposals were ratified and which were not, consult the early congressional documentation that lists the proposals and state actions Congress.gov ratification records.
One of the two unratified proposals addressed congressional compensation and did not achieve the needed approvals in the 1791 period. That same proposal later took a very long path before it was eventually ratified more than two centuries later in 1992 as the 27th Amendment. The National Constitution Center summarizes the history of the two outstanding proposals and the unusual late ratification of the compensation amendment National Constitution Center history of the 27th Amendment.
The delayed ratification of the congressional compensation amendment is treated as a separate historical episode from the 1791 ratification of the first ten amendments. Its long arc underscores that an amendment’s path to adoption can vary, and that the mere existence of a proposal in 1789 did not guarantee near term ratification National Constitution Center history of the 27th Amendment.
How Bill of Rights Day is observed today
December 15 is commonly observed as Bill of Rights Day to mark the anniversary of the ten amendments’ ratification, and many museums, archives, and educational institutions use the date for programs and displays that highlight the historical record and the texts themselves. Coverage and examples of programming around the date are described in summaries of observance practices History.com overview of Bill of Rights Day. The National Archives also offers materials online National Archives transcription.
Observances vary widely. Some institutions hold public readings or exhibit original or facsimile documents, while others organize classroom sessions or community events aimed at explaining the amendments and their historical context. The National Archives and similar institutions often place transcriptions and digitized materials on view or online to coincide with December 15 National Archives transcription.

Common misunderstandings and questions about the ratification date
A frequent error is to conflate the Constitution’s adoption with the Bill of Rights ratification. The Constitution was completed in 1787, while the Bill of Rights amendments were proposed in 1789 and ratified by the states in 1791, so the two events are separate and have different dates; primary transcriptions make that distinction clear National Archives transcription.
Another common misunderstanding is the idea that the Bill of Rights was part of the original constitutional text presented at the Philadelphia convention. In fact, the amendments were developed after the Constitution was submitted to the states, and the First Congress took the lead in proposing the changes that would later be ratified by the states Library of Congress primary documents. See our constitutional rights page.
For readers asking when was the Bill of Rights ratified, the clear documentary answer is December 15, 1791, recorded in archival transcriptions and congressional records.

Practical examples: classroom activities and museum programming for Bill of Rights Day
Teachers and civic educators can use December 15 as a concrete anchor for short activities that bring primary texts to life. One straightforward exercise is a document comparison where students read the National Archives transcription of an amendment, then compare it to a modern summary to discuss wording and interpretation National Archives transcription, and materials from the Bill of Rights Institute Bill of Rights Institute primary sources.
A second activity is a timeline workshop that has students place key dates on a classroom timeline, including the congressional proposal on September 25, 1789, and the December 15, 1791 ratification milestone. This helps clarify the Bill of Rights timeline 1789-1791 and shows how amendments moved from proposal to ratification across states Library of Congress primary documents.
