Oh gourd

Missouri was as split during the federal period as it was in the ACW, that is a given. 40 odd years after statehood, little had changed yet the majority of MO slavery was way down south in Dixie, as it were. That leaves most of the states demographic little different than several other western states (Illinois, fer instance).
My points have been targeted to those very northern communities that contributed to and were mustered in by Confederate forces. Even the St Louis/Camp Jackson events leading to civilian bloodshed had more to do with military intervention than racial equality. I believe I mentioned standing militia in my initial post to this thread. I would be repeating myself in pointing out that by the time of the ACW, there was comparatively little slavery in the state and that even the politicians and military of the state were no less moderate in stance than Lincoln himself.
Union control of the state having little or nothing to do with slavery when ushering in martial law controlling the state while very northern non slavery homeowners and merchants gathering in Confederate musters borne out of those local militia. Price and the boys a figurehead of that. A part of that loyalty to those seniors remembered back to the Mexican War.
Kentucky and Virginia the other two major split states as far as musters went and again, more raised against push come to shove amongst many that never had and never would own slaves. A reactionary muster, clamoring and waving a don't tread on me attitude.
To finish as I began this post, the slavery powder keg as volatile before 1820 as it was in 1860. MO was more a matter of Union logistics controlling transportation than fighting to free slaves.
