The "Border States" were slave states.
The border between slave and free states east of the Mississippi River was largely defined by the Mason-Dixon Line and the Ohio River. This division was established during the early 19th century as states entered the Union. The exception to this border was Missouri, which was a slave state located north of the Ohio River, complicating the geographical and political landscape of slavery in the United States.
The Union in the American Civil War represented the free states (meaning slave-free states) plus five border slave states in the north of America. The Confederate States of America (the Confederacy) comprised the eleven southern slave states which had seceded from the United States of America.

The Union states that bordered seceding states included both free and slave states. For instance, Pennsylvania and Ohio were free states that bordered the slave states of Virginia and Kentucky. Additionally, Missouri, which was a border state with divided loyalties, had Union and Confederate sympathizers but was also adjacent to free states like Illinois and Iowa. Thus, the border regions were complex, reflecting a mix of free and slave state dynamics.
