West Virginia 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.
A common story told about West Virginia is the folktale about how it got the nickname "West, By God, Virginia". According to the legend, a West Virginia native who was being inducted into the US Army during the First World War (some versions make it as early as the Spanish-American War), was repeatedly asked by his induction officer, "What part of Virginia?" And the soldier, finally getting fed up with the confusion, said "Not Virginia! West Virginia! West, by God, Virginia!". This story, whether true or not, has entered American folklore, and it is not unusual to hear not only West Virginians themselves, but other Americans, refer to the state as "West, By God, Virginia", or often as "West By-God", or sometimes simply as "By-God".
