History
Created on May 15, 1772, by an act of the House of Burgesses from the northern third of Frederick County when it was part of Virginia, Berkeley County went on to become West Virginia's second-oldest county after that state seceded from Virginia in 1863 during the Civil War. At the time of the county's formation, Berkeley County comprised areas that now are part of present-day Jefferson and Morgan counties in West Virginia.
Most historians believe the county was named for Norborne Berkeley, Baron de Botetourt (1718–1770), Colonial Governor of Virginia from 1768 to 1770. West Virginia's Blue Book, for example, indicates Berkeley County was named in his honor. He served as a colonel in England's North Gloucestershire militia in 1761, and represented that division of the county in Parliament until he was made a peer in 1764. Having incurred heavy gambling debts, he solicited a government appointment and in July 1768 was made Governor of Virginia.
