John Adams, Letter to Richard Henry Lee, November 15, 1775

John Adams on a New Form of Government, 1775

More than a decade before the Constitutional Convention in 1787—and months before the United States declared independence—John Adams wrote a plan for a new form of government for the American colonies. The ideas presented in this letter had a profound influence on the state constitutions of Virginia, New York, Massachusetts, and ultimately, the federal Constitution.
