Virginia Ratifies the US Constitution and is the 10th State Admitted to the Union

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 in 1846 the Virginian area was retroceded. Virginia is sometimes called "Mother of States" because of its role in being carved into several mid-western states
