The Pinckney Plan was a proposal to the Constitutional Convention made on May 29, 1787, by Charles Pinckney, a delegate to the Convention from South Carolina. The original draft of the plan has been lost; the details contained herein are pieced together from notes to the Convention made by James Wilson that were not discovered until the 20th century. Scholars have had some difficulty determining what was in the Pinckney Plan, in part due to Pinckney himself. On request from John Quincy Adams, who was putting together records from the Convention, Pinckney produced a draft of his plan in 1818 that many scholars, including James Madison, have said is too close to the final draft of the Constitution to be accurate. The accuracy of this draft of his plan is still disputed. Because of the uncertainty regarding what was in the plan and its original contents, the affect it had on the final draft of the Constitution is difficult to ascertain.
