Another unfun fact, that's why Oklahoma has a panhandle. Texas wanted to enter the Union as a slave state, but it wasn't allowed below a certain line of latitude. So Texas gave up some of its territory to ensure it could enter as a slave state, and a portion of that territory became the panhandle.

Another unfun fact, Oregon wasn't a slave state, because their black exclusion laws defined that slavery and involuntary servitude shall be forever prohibited in Oregon and than any "negro or mulatto" residing in the state for more than six months would receive 39 lashes.

It was amended a few months later due to the lashes being seen as "excessive" so that instead the punishment was to "publicly hire out" the individual for the "shortest term of service" after which they would need to be removed within 6 months.

It really set the template for the sort of "just slavery with extra steps" that became the 13th amendment and post-emancipation US.

Mormon history is so exceedingly bloody and fucked up that is actually kind of amazing how thoroughly they've been able to reverse that completely and convince outsiders that they're just peaceful, pleasant people.
