Probably because MO was a Union state.
it was definitely not a free state.
MO was a border state but BEFORE the Civil War in 1858, Missouri was a slave state considered South. Also note that Maryland and Delaware which remained in the Union were also included in the South on that map because they were also slave states.
It was a border state and I bet Jessie James, Bloody Bill and co would have a problem with you saying that.
Jackson was the Confederate governor of Missouri during the war, and Missouri had representatives seated in the Confederate congress.
The state was occupied by Unionist forces for much of the war, which put in place a puppet government.
Kentucky and Tennessee were also Union states, but they are placed in the South.
Not true. It was occupied by Union forces, but it did, in fact, secede from the union.
Thus a slave state till the end of 1865. Like Kentucky, Delaware and Maryland.
Probably because MO was a Union state.
Huh? No, no, no!!
Missouri was a slave state. It was part of the Missouri Compromise which admitted Maine to the USA at the same time that Missouri was admitted. One free state and one slave state.
When the German immigrants began arriving in Missouri, it caused a lot of stress in the population as German immigrants were totally anti-slavery. They were mostly Lutherans, Catholics and Methodists. President Lincoln called for volunteers to protect the Union properties. The largest part of the Missouri GAR volunteers were German immigrants.
