The Bill of Rights, the first 10 amendments to the U.S. Constitution, was ratified on December 15, 1791.

This pivotal moment came after Congress approved the amendments on September 25, 1789, sending them to the states for ratification, where Virginia's approval as the 11th state sealed the deal three-quarters of the way through. James Madison championed these protections for individual liberties amid debates between Federalists and Anti-Federalists, ensuring freedoms like speech and religion were enshrined early in the nation's history.

Timeline Breakdown

Here's a clear sequence of key events leading to approval:

  1. June 1789 : Madison introduces proposed amendments in Congress.
  2. September 25, 1789 : Congress approves 12 amendments (10 of which became the Bill of Rights) and sends them to states.
  1. December 15, 1791 : Virginia ratifies, hitting the three-fourths threshold for official adoption.

Approval vs. Ratification

  • Congressional Approval : September 25, 1789—formal passage before state submission.
  • State Ratification : December 15, 1791—the date it became law, as three-fourths of states agreed.

This distinction matters: "Approved" often points to Congress's action, but full effectiveness required ratification.

Lasting Impact

Even in March 2026, the Bill of Rights shapes debates on free speech and privacy, with its 235th anniversary approaching next year. Some states like Massachusetts ratified symbolically in 1939.

"By December 15, 1791, three-fourths of the states had ratified 10 of these, now known as the 'Bill of Rights.'"

TL;DR: Ratified December 15, 1791; Congress approved September 25, 1789.
