West Virginia
West Virginia was once a part of Virginia. At the beginning of the American Civil War, Virginia and the other southern states seceded from the United States, which means they chose to not be a part of it anymore. Slaves were fewer in the west than in other parts, and those in West Virginia who were against slavery were not objecting on moral grounds. They saw it as bad for free labor. While slavery was an issue in other parts of Virginia, in the western counties the issues were taxation and being governed from a state capital that was far away. The people in Western Virginia had far more in common with their neighboring states of Pennsylvania and Ohio than with the Commonwealth of Virginia. So this was an area of Union support.
