Rufus King (1755-1827) was one of the Founding Fathers. He served briefly in the American Revolution, practiced law in Massachusetts, and became a member of the Massachusetts General Court from 1783 to 1785.
King was a delegate to the Continental Congress (1784-87) who helped draft the Ordinance of 1787 for the settlement of the Northwest Territory, and was chiefly responsible for the provision excluding slavery from that region. He was a member of the Massachusetts delegation to the 1787 Constitutional Convention and helped to secure Massachusetts's ratification of the Constitution. A strong supporter of Alexander Hamilton, King became a Federalist Senator from New York.
