Introduced in 1789, this is James Madison’s original proposal for the amendments that would later become the Bill of Rights. While Madison had originally been opposed to the inclusion of a Bill of Rights, several political developments had convinced him it would be necessary to include one to prevent a second constitutional convention, which some Antifederalists were calling for. In this proposal, Madison includes 19 proposed amendments, 7 of which Congress rejected. Though language in several clauses is different from the wording Congress eventually adopted, some of the language Madison uses is explicitly codified in the Bill of Rights, such as in the Third, Fifth, and Tenth Amendments.
