Plz i give mark ! list the border states. why do you think these states did not join the confederacy even though they precticed slavery?

The border states during the Civil War were the slave states that didn't leave the Union. These states included Delaware, Kentucky, Maryland, and Missouri. West Virginia, which separated from Virginia during the war, was also considered a border state... Not everyone in the border states supported the Union. In some cases, like Missouri and West Virginia, the support for each side was fairly evenly split. Thousands of soldiers from the border states headed south and joined the Confederate Army. There was also politicians in these states who fought hard for secession. Even if they didn't want secession, many of the people of the border states thought the war against the Confederacy was wrong. They felt that the states should be able to leave the country if they wanted to.
