Realistic Independent Confederate States

[Wakie77]

You end up with a very fractured America which has huge waves in history.

Texas would quickly become an independent Republic.  New York City would pull out of the Union.  As time goes on various states would pull out of the bigger unions over various divides.  I gotta believe you would have an independent Mormon Utah under theocratic rule.  The quality of life for blacks in the South is even worse as some states move towards emancipation and others don't.  Technology makes owning slaves a losing proposition so you likely get all kinds of atrocities.

Westward expansion is slowed as the construction of railroads across national borders slows it down.  Inevitably you would have some wars between American states.  Women's suffrage would cause some states to break off.  WWI goes on longer but has the same outcome.  The evolution of Communism in Europe may take root in some of the North American states.

American involvement in WWII is less significant as many states stay out.  The Empire of Japan dominates the Pacific.  The Nazi's dominate Western Europe but end up locked in a brutal war of attrition with the USSR which grinds into the 1950s.

The end result can only be
1- The war grinds to a halt with a Cold War between the Soviet Union and  Nazi Europe.
OR
2 - The Soviets eventually win the war of attrition and dominate Europe and push their influence into the America's with the only major resistance coming from forces backed by the Japanese.
OR
3 - The Nazi's develop the Atom Bomb and use it to defeat the Soviets.  This means a Nazi empire throughout Europe and much of the former Soviet Union.

If you want more I can probably write a book but I doubt anyone here would really buy it.
