About Governor Thomas Sim Lee

Thomas Sim Lee (October 29, 1745 – November 9, 1819) was an American planter and statesman of Frederick County, Maryland. Although not a signatory to the Declaration of Independence, the Articles of Confederation or the US Constitution, he was an important participant in the process of their creation. Thomas Sim Lee was the second Governor of Maryland, serving twice, from 1779 to 1783 and again from 1792 to 1794. Thomas Sim Lee also served as a delegate of Maryland in the Congress of the Confederation in 1783 and was a member of the house of delegates in 1787. He worked closely with many of the Founding fathers and played an important part in the birth of his state and the nation.

Thomas Sim Lee was born in 1745 in Upper Marlboro, Maryland. He was the son of Thomas (d. 1749) and Christiana (Sim) Lee and descended from the "Blenheim" branch of the Lee family of Virginia. Richard Lee I was his great-great-grandfather. His education was attained in the private schools of his native state. On October 27, 1771, Thomas Sim Lee married Mary Digges (1745–1805), whose father was a prominent Maryland landowner. They had eight children;

  • Ignatius Lee (b. 1772)
  • Thomas Lee (1774–1826)
  • William Lee (1775–1845)
  • Eliza Lee (born c. 1777)
  • Archibald Lee (1778–1781)
  • Archibald Lee (1781–1839)
  • Mary Christian Lee (born c. 1783)
  • John Lee (1788–1871)

During the Revolutionary War, he backed the patriot cause, and organized a local militia in which he served as colonel. Lee entered politics in 1777, serving as a member of the Maryland Legislature, a position he held two years. The Maryland Legislature elected Lee governor in 1779. He was reelected in 1780 and 1781. During his first tenure, issues regarding the war effort were dealt with. He won wide praise for his logistical abilities as governor. Lee consistently procured fresh troops and supplies for the Continental Army. George Washington was Lee's friend, and learning of the plan to pin down Cornwallis, Lee exerted all his energies to support the American troops. After completing his term, Lee left office on November 22, 1782. He then served in the Continental Congress in 1783 and 1784, and was a member of the State convention that ratified the U.S. Constitution in 1788. In 1792, Lee was again elected governor of Maryland. He was reelected to a second term in 1793, and to a third term in 1794. During his final tenure, the state militia was established, and the Whiskey rebellion was suppressed. Lee left office on November 14, 1794. Later that same year, he declined a seat in the U.S. Senate. He also declined a third tenure as governor in 1798.

Thomas Sim Lee was one of the participants of the Annapolis Convention in the mid 1770s, which produced a constitution for Maryland and transformed the colony into a state. On July 26, 1775 he was one of the signatories of the Declaration of the Association of the Freemen of Maryland, an influential statement in the Revolutionary War.

Governor of Maryland, Thomas Sim Lee, signed the Act on Feb. 2, 1781 whereby the Maryland Legislature ratified the Articles of Confederation and Perpetual Union. As Maryland was the 13th and final state to ratify the Articles, the act established the requisite unanimous consent for the formation of a Perpetual Union of the states.

Prior to this event, Maryland had held out and refused to ratify the Articles until every state had ceded its western land claims. After Governor Thomas Jefferson signed the Act of the Virginia legislature on January 2, 1781 to grant these concessions the way forward for Maryland was cleared. On this second day of February, a Friday, as the last piece of business during the afternoon Session, "among engrossed Bills" was "signed and sealed by the Governor, in the Senate Chamber, in the presence of the members of both Act to empower the delegates of this state in Congress to subscribe and ratify the articles of confederation." The Senate then adjourned "to the first Monday in August next". The formal signing of the Articles by the Maryland delegates took place in Philadelphia at noon time on March 1, 1781. With these events, the Articles entered into force and the United States came into being as a united and sovereign nation.

In his post-governor career, Thomas Sim Lee represented Maryland as a delegate to the Continental Congress in 1783 and 1784. He also was a member of the house of delegates in 1787. He declined the opportunity to serve in the convention that drafted the Constitution of the United States, but served in the state convention that ratified the Constitution in 1788. Lee voted for Washington's second term as a Federalist presidential elector.

Governor Lee's wife, Mary Digges Lee, responded to the need of the Revolutionary War troops from Maryland by rallying the women of Maryland to raise money in support of the war effort. She then established a correspondence with General George Washington, asking how these resources could be put to best use. General Washington responded suggesting that the money raised be put toward the purchase of much-needed shirts and black neck clothes for the troops in the Southern army. He expressed gratitude to Mrs. Lee for the "patriotic exertions of the ladies of Maryland in favor of the army".

The couple was very active in patriotic activities during the Revolutionary War. They were also very committed to their religious and community ties. They founded the St. Mary's Roman Catholic Church in Petersville, Maryland.

After retiring from political life in 1794, Governor Lee focused his attention on his estate, Needwood, in Frederick County, Maryland, where he owned some two hundred slaves.

Lee set up a winter home in Georgetown, near the nation's capital. Federalists frequented the home, which became a meeting place for them.

Thomas Sim Lee was on the Board of directors of the Patowmack Canal, which was intended by George Washington to connect the Tidewater near Georgetown with Cumberland. The project, which started in 1785, was completed in 1802.

Mary Digges Lee died on January 25, 1805 at the age of 60 years old. Thomas Sim Lee remained a widower in Needwood until his death on November 9, 1819 at the age of 74 years old. He was first buried at Melwood Park, his wife's family home. In 1888 he and the Melwood Diggeses graves were moved to Mt. Carmel Roman Catholic Cemetery near Upper Marlboro, Maryland to a common grave.

A bronze plaque commemorating his life has been placed on a house he built in 1790 on 3001-3009 M Street (on the corner of M Street and 30th Street) in the Georgetown section of Washington D.C.. The site is now referred to as the Thomas Sim Lee Corner.
