Wilson Cary Nicholas was an American politician who served in the U.S. Senate from 1799 to 1804 and was the 19th Governor of Virginia from 1814 to 1816.
Nicholas continued to reside in Albemarle County after the war, where he owned and operated a plantation along the James River which he called Mount Warren. He was a member of the Virginia House of Delegates from 1784 to 1785 and 1788 to 1789. He was a delegate to the ratifying convention of 1788, which approved the Federal Constitution. During the deliberations, on June 6, 1788, Nicholas countered Patrick Henry's objection that correcting defects in the new national Constitution by way of the Article V convention would be excessively difficult. Nicholas said, "The conventions which shall be so called will have their deliberations confined to a few points; no local interest to divert their attention; nothing but the necessary alterations. They will have many advantages over the last Convention. No experiments to devise; the general and fundamental regulations being already laid down." From 1794 to 1800, Nicholas served again in the House of Delegates. He was elected as a Democratic-Republican to the US Senate to fill the vacancy caused by the death of Henry Tazewell and served from December 5, 1799, until May 22, 1804, when he resigned to become collector of the port of Norfolk 1804–1807. He was elected to the US House of Representatives in the Tenth and Eleventh Congresses and served from March 4, 1807, until his resignation on November 27, 1809. He was elected Governor of Virginia in 1814 and served until 1816, when he retired from office. Nicholas also served as president of the Richmond branch of the Second Bank of the United States. His speculations in western lands put him in serious debt during the Panic of 1819. Having convinced Thomas Jefferson to endorse two of his notes for $10,000 each, he also plunged Jefferson into debt.
The brothers of Wilson Cary Nicholas included attorneys George Nicholas and John Nicholas. Another brother, Philip Norborne Nicholas served as Virginia's attorney general from 1800 to 1819. Nicholas was married to Margaret Smith of Baltimore. His brother George was married to Margaret's sister, Mary. Margaret and Mary Smith were the sisters of Samuel Smith and Robert Smith. The children of Wilson Cary Nicholas and Margaret Smith Nicholas included Mary Buchanan, Charlotte G., Jane Hollins, John Smith, and Sidney Smith.
