Virginia's friction with Britain increased during the late Colonial period with the instigation of the Stamp Act and Townshend Acts. Following the Boston Tea Party, Virginia's governor dissolved the House of Burgesses to prevent it from becoming an antigovernment forum. Members of the body reassembled at Raleigh Tavern to call for a convention of all the colonies. The First Continental Congress met in Philadelphia with a Virginian, Peyton Randolph, presiding. The state's principal military contribution to the Revolution was provision of men and supplies to the army. In May 1781, Gen. Cornwallis entered Virginia from the south for an unsuccessful campaign against Lafayette, which ended with the British surrender at Yorktown. Virginia ratified the U.S. Constitution in 1788.
