Rufus King

Rufus King (1755–1827) was a Founding Father, constitutional framer, Federalist statesman, and one of the earliest and most persistent American opponents of slavery's expansion. A Harvard-educated lawyer who served in the Continental Congress, the Constitutional Convention, the U.S. Senate, and as Minister to Great Britain, King bridged the revolutionary generation and the early republic — carrying the original intent of the framers into the governance of the new nation for nearly four decades. His anti-slavery speeches during the Missouri Crisis of 1819–1820 represent some of the most forceful constitutional arguments against the extension of slavery delivered by any member of the founding generation.

Definitions

Federalist Party: The political faction, led by Alexander Hamilton and John Adams, that advocated for a strong central government, sound national finance, and close commercial ties with Great Britain. King was one of its most prominent members and its last presidential nominee (1816).

Committee of Style: A five-member committee at the Constitutional Convention (including Gouverneur Morris, Alexander Hamilton, William Samuel Johnson, James Madison, and Rufus King) charged with arranging and polishing the final text of the Constitution.

Committee on Postponed Matters: A Constitutional Convention committee that resolved unfinished and contentious issues, including the method of presidential election and treaty powers.

Northwest Ordinance (1787): Legislation governing the Northwest Territory that established a pathway to statehood, guaranteed civil liberties, and prohibited slavery north of the Ohio River — incorporating language King had introduced in the Continental Congress in 1785.

Three-Fifths Compromise: The constitutional provision (Article I, Section 2) counting three-fifths of enslaved persons for purposes of representation and taxation. King accepted it as a necessary concession in 1787 but later called it one of the "greatest blemishes" on the Constitution.

Missouri Compromise (1820): The legislative agreement admitting Missouri as a slave state and Maine as a free state while prohibiting slavery in territories north of 36°30′. King led the opposition to this compromise in the Senate.

Minister Plenipotentiary: The highest-ranking diplomatic envoy of the United States to a foreign court; King served in this capacity to the Court of St. James's (Great Britain) twice (1796–1803, 1825–1826).
