I came up with this thought when learning that the state allowed segregation after emancipation, but what if William Quantrill and the pro-slavery forces emerged victorious in Kansas during the skirmish infamously known as "Bleeding Kansas"? Obviously KS would be admitted to the union as a pro-slavery state. When the American Civil War would come around, do you think a pro-slavery KS would secede or remain in the Union as a Border State?
