What Are Border States?

Picture the map of the United States in 1861. But the Union didn’t just split into a clean North‑South divide. There were six states—Delaware, Kentucky, Maryland, Missouri, West Virginia, and Pennsylvania—that had a foot in both worlds. They were called border states because they bordered the slave‑holding South while remaining part of the Union And that's really what it comes down to..

They had slave‑holding economies like the Deep South, but they also had industrial towns, free‑labor cities, and a mix of pro‑Union and pro‑Confederate sympathies.
