I have been waiting for a good British America discussion for awhile, so this thread makes my day.
In a timeline where the British keep America, let's say the Albany Plan or the Galloway plan goes through, what are the biggest cities in British America in 2021? I'm imagining all the land the United States has today, plus Canada, plus like Bermuda and the Bahamas and Jamaica. I have a timeline imagined for the acquisition of all of this land, which involves the British beating Napoleon and taking the Louisiana Territory, and the British being able to take Mexico. Easily. Maybe get even more land. But anyway that's not the point. The point is which cities will be big in this timeline? I imagine similar to OTL if you would combine USA and Canada, but I don't know.
- The Albany/Galloway plan are unlikely because it's unifying the colonies against Britain, whereas if the colonies remain entities, Britain can play New York off against Virginia.
- And the alternate history scenario just becomes an United States within the British sphere.
Working with this scenario.
- New York (Financial center), Philadelphia (Political Capital), a Great Lakes city (Industrial/Transport hub), Vancouver (it has a better port location than Seattle), Los Angeles or San Francisco (Pacific Port city)
Napoleon is butterflied as whatever allows Britain to hold the 13 Colonies would affect France. Such as ARW averted, means French Revolution delayed or prevented. Or ARW ending before French involvement. Or somehow Britain winning ARW once international involvement, which I don't know what effects that would have on Napoleon's rise to power.
Spain will most likely be in control of the Louisiana territory, so whatever war replaces the ARW in the 1770-1800 period could see that land being seized by British colonists, however where the border is drawn is hard to determine. Eventually Britain would span coast to coast, either through war with Mexico or purchase of land.
British America would look very different to otl US and Canada, this is because these countries developed separately. For example, no ARW, means no mass migration of English loyalists to Nova Scotia, thus no New Brunswick. Or Ontario being more industrialised because of access to the US market. Americans would expand west, and this would draw people from expanding north, thus leaving Canadian territories less populated. The North-South dynamic in the US would be averted, because of the different system of governance within the Albany/Galloway plan, and because the North has Newfoundland, Nova Scotia, Quebec and Ontario.
Externally British America would look territorially similar to OTL US & Canada, but internally everything is different from OTL US & Canada.
