Cuban Butterflies

In this TimeLine (TL) there is one, primary Point Of Divergence (POD) - The selling of Cuba to the United States of America by the Spanish Empire in 1848. This leads to a far more fractured nation in which the Northern States (or 'Free States') are more fearful of the Southern States (or 'Slave States') imposing slavery back onto the USA as a whole. The political ramifications of this hit hard in 1860 and the world changes, forever.
