West Virginia (IPA: /ˌwɛstvɚˈʒɪnjə/) is a state in the Appalachia / Upland South region of the United States. West Virginia broke away from Virginia during the American Civil War and was admitted to the Union as a separate state on June 20, 1863 (an anniversary now celebrated as West Virginia Day in the state). It is one of only two states formed during the American Civil War (along with Nevada) and is the only state to form by seceding from a Confederate state and one of two states to secede from another state (Kentucky also seceded from Virginia but before the Civil War).
