Another borderline ASB Ameriwank map of mine. Apparently I'm known for liking Ameriwanks, and I've only been here a month and a half. Nice.
Ignore my atrocious territory borders, please.
So the US gets everything south of the St. Lawrence. Thank you, Nova Scotia and half of Quebec for rebelling.
During the Constitutional Convention, Thomas Jefferson witnesses a huge argument between pro-slavery and anti-slavery factions. He sees the future and decides to take a step to avoid it.
He teams up with fellow abolitionist founding fathers (of which there were apparently quite a few) and manages to get slavery abolished in Virginia by 1800. As Virginia was quite the leader at the time, Maryland, Delaware, DC, and future Kentucky all abolish slavery. North Carolina follows narrowly (by one vote it became a free state) which liberates future Tennessee and even Arkansas. Stephen Austin can't convince the Mexican government to let the American Texans to keep their slaves, so Texas is thrown into the free state camp when it joins.
When the Mexican-American War rolls around, support is almost unanimous because the Northerners aren't afraid of slavery and the Southerners see it as a place to expand the peculiar institution to. The Americans push much harder and manage to get modern-day Baja California (and Sur), Sonora, Sinaloa, and parts of Chihuahua along the Rio Conchos.
Anyway, TTL's Wilmot Proviso analogue passes Congress and this is where the Deep South secedes. The US can easily take these six states, though it's a little hampered by a few Mexican revolts out west.
The Civil War is done with in about a year and a half; it extends from 1850 to 1851. Slavery is officially abolished as a more complete Reconstruction takes place.
Anyway, that's the general overview.
I believe this is only Semi-ASB, though I might have used my butterfly net a little too liberally.
Things I'm stuck on: State boundaries, especially in the Great Lakes area, Missouri, and Texas.
A few fun facts about this map: California doesn't include San Diego; it's a truly straight line from the Colorado-Gila junction this time.
The states are probably going to be named what they are OTL, though I might mess around with the Great Lakes a bit. I'm planning on having Nova Scotia give up New Brunswick, which will be given the misnomer 'Acadia'. I don't know about the Quebec areas, however.
List of territories on this map: The Baja Territory, Sonora Territory, New Mexico Territory, Kansas Territory, Minnesota Territory, Iowa Territory, Nebraska Territory, Utah Territory, Indian Territory and Oregon Territory.
