Passage: The British Parliament's efforts to levy new taxes following the French and Indian War were deeply unpopular in the colonies. In the House of Burgesses, opposition to taxation without representation was led by Patrick Henry and Richard Henry Lee, among others. Virginians began to coordinate their actions with other colonies in 1773, and sent delegates to the Continental Congress the following year. After the House of Burgesses was dissolved by the royal governor in 1774, Virginia's revolutionary leaders continued to govern via the Virginia Conventions. On May 15, 1776, the Convention declared Virginia's independence from the British Empire and adopted George Mason's Virginia Declaration of Rights, which was then included in a new constitution. Another Virginian, Thomas Jefferson, drew upon Mason's work in drafting the national Declaration of Independence.When the American Revolutionary War began, George Washington was selected to head the colonial army. During the war, the capital was moved to Richmond at the urging of Governor Thomas Jefferson, who feared that Williamsburg's coastal location would make it vulnerable to British attack. In 1781, the combined action of Continental and French land and naval forces trapped the British army on the Virginia Peninsula, where troops under George Washington and Comte de Rochambeau defeated British General Cornwallis in the Siege of Yorktown. His surrender on October 19, 1781 led to peace negotiations in Paris and secured the independence of the colonies.Virginians were instrumental in writing the United States Constitution. James Madison drafted the Virginia Plan in 1787 and the Bill of Rights in 1789. Virginia ratified the Constitution on June 25, 1788. The three-fifths compromise ensured that Virginia, with its large number of slaves, initially had the largest bloc in the House of Representatives. Together with the Virginia dynasty of presidents, this gave the Commonwealth national importance. In 1790, both Virginia and Maryland ceded territory to form the new District of Columbia, though the Virginian area was retroceded in 1846. Virginia is called the "Mother of States" because of its role in being carved into states such as Kentucky, which became the 15th state in 1792, and for the numbers of American pioneers born in Virginia.
Question: What is the first name of the person whose work Thomas Jefferson drew upon in drafting the national Declaration of Independence?
