The Commonwealth of Virginia is a U.S. state on the Atlantic Coast of the Southern United States. Nicknamed the "Old Dominion" and sometimes the "Mother of Presidents" due to Virginia being the birthplace of eight U.S. presidents. The geography and climate are shaped by the Blue Ridge Mountains and the Chesapeake Bay. The climate becomes increasingly warmer farther south and east. The capital of the Commonwealth is Richmond and Virginia Beach is the most populous city. Virginia is bordered by Maryland and Washington, D.C. to the north and east; by the Atlantic Ocean to the east; by North Carolina and Tennessee to the south; by Kentucky to the west; and by West Virginia to the north and west.
