After West Virginia became a state, there were disagreements among Union and Confederate supporters, and often among Union supporters themselves. Some, like West Virginia's first governor, Arthur Boreman, were called Unconditional Unionists. They supported freeing enslaved people and giving the federal government more power. Others, known as Conservative Unionists, disagreed because they thought the government was too controlling and didn’t want slavery to end. In a compromise, West Virginia became the last slave state to enter the Union, with a provision that enslaved people would gradually be emancipated.
