Congress approved twelve articles of amendment on September 25, 1789, after House and Senate revisions, and submitted them to the state legislatures on October 2, 1789.

Largely through James Madison's efforts, Congress approved twelve articles of amendment on September 25, 1789. The House had taken up Madison's proposal as a full body beginning July 21, 1789, after a procedural battle; revisions condensed twenty amendments to seventeen, forwarded to the Senate on August 24, 1789. The Senate eliminated Madison's proposal to apply parts of the Bill of Rights to the states and condensed the seventeen to twelve, approved September 9, 1789. A House–Senate Conference Committee finalized twelve amendments on September 24, 1789, and the joint resolution was officially submitted to the state legislatures on October 2, 1789.
