<P> The Preamble was placed in the Constitution during the last days of the Constitutional Convention by the Committee on Style , which wrote its final draft , with Gouverneur Morris leading the effort . It was not proposed or discussed on the floor of the convention beforehand . The initial wording of the preamble did not refer to the people of the United States , rather , it referred to people of the various states , which was the norm . In earlier documents , including the 1778 Treaty of Alliance with France , the Articles of Confederation , and the 1783 Treaty of Paris recognizing American independence , the word `` people '' was not used , and the phrase the United States was followed immediately by a listing of the states , from north to south . The change was made out of necessity , as the Constitution provided that whenever the popularly elected ratifying conventions of nine states gave their approval , it would go into effect for those nine , irrespective of whether any of the remaining states ratified . </P>
