This topic is product of reading almost(still lack a lot) of the Magnum Opus called Decades of Darkness and some enquiry about the USA....
We have a lot(the second Cliche of AH, First are the nazis) of the Confedearacy/Old Southern victory/surviving scenario, leaving the rest of *USA like the succesor(when in some way, the Southern area was when a lot of the first politician of the USA come from), but...
What if are the northern areas(like every upper virginia) who disapointed of the federal politics pro-south(add more agricultural/protecionist/pro slave here like the POD), decide to form another federal state in North America(New England if smaller, North American Federation, etc).
Again my scenario is very basic(lack of time for more detail), but again what will be the effect,... the Rump Slave South *United States of America(who still keep the name), again the North Federation like???, how will be their effect in the continent(the expasionism, canada, etc), effect in geopolitics(it's happen after the congress of Vienna), and etc
that is my enquire
