AHC: Get North America to look like this:

[The_Russian]

Ok. So I’m wondering wondering if it’s plausible to get Texas to at least this extent or more with a POD of 1836: https://i.pinimg.com/originals/3a/b1/2b/3ab12be461f5a46800b274a37ccb8b7a.png

The alternate map doesn’t have to be this exactly, but Texas has to contain all of Modern day California, New Mexico, Arizona, and most of Utah, Colorado, and Nevada. Bonus points if you get Texas to be larger.

How would the US and Texas develop if this map happened? How would the west coast and Texas develop specifically?

Well, it probably won't be Texas. OTL Texas had to fight very hard for independence and it was close a few times. To get the whole of northern New Spain/Mexico it needs the rebellion of the whole north which would include some land south of the Rio Grande.
Some sort of Mexican Civil War turned secession backed by the US and probably UK might work.

What I'm thinking is Texas gets backed by a major power, and goes to war with Mexico to annex all it's claims. During the war could California still declare independence and instead join Texas ITTL?

 

[Atamolos]

Pretty unlikely. Modern Texas is economically strong and has a robust population with many large ports, but at the time of independence, Texas had a relatively tiny population and the war for independence left their economy in shambles. They were in so much debt by the time of annexation, that they sold a huge portion of their original territory to the US federal government (which is why the eventual state of Texas was so much smaller than the Republic of Texas)

That map also includes an independent Quebec that includes all of maritime Canada, which implies a POD in the mid-18thC at the latest. It's a monarchy too, which implies the French revolution never happened either. I don't see how that can be remotely possible with a post 1836 POD.

As for just the Texas bit - make the Bear Flag revolt larger and more successful and have Fremont elsewhere at the time so the Californians call on the Republic of Texas for support instead. Whackiness ensues, California merges with Texas in a federal republic and the gold rush comes along on Schedule to solve Texas' economic problems allowing the new state to prosper and assimilate immigrants.

I'm well aware there's enough handwaving in that to leave the author hovering a couple of feet off the floor, but...

I wasn't focusing on Quebec. That is why I said you didn't have to make the alternate map be the exact same.

Anyway, yea for Texas I think what you suggested works. Thanks

In that case, "Texas" will basically be a federation dominated by both Texas and California, with California clearly the dominant partner.

Not necessarily. IOTL, there was almost a monarchical restoration in France after the Franco-Prussian War; it failed because the head of the royal house refused to reign under the tricolor. Or, Quebec could be Bonapartist, or it could be under the British royal house. For that matter, perhaps what happened is the federation of Upper and Lower Canada failed, they got responsible government separately, and someone chose to call them "Principalities" instead of coining the new word "Dominion." (They almost called Canada a Kingdom IOTL, except they were worried about American objections.) The West and the Maritimes, then, would be annexed to their nearest neighbors later.

Regarding Texas... Let's not forget they also have the Mormons in Deseret. How might they be involved?

 

[Galba Otho Vitelius]

Super-Texas is not that difficult. The trick is to either have Mexico win the Mexican-American War outright, curb stomping the Americans as badly as they were curb-stomped IOTL, or, which is more likely, the Mexicans at least crush the Texas rebellion and in the USA the Whigs get their way and the Americans neither attack Mexico or support filibustering expeditions to Texas and California. So Mexico retains all of those states.

Then the mid-nineteenth century Mexican civil war kicks off on schedule. Because of butterflies, the conservatives get their monarchy installed in Mexico City and most of the country. However, the liberals under Juarez are able to maintain an "Estados Unidos Mexicanos" in the nothern tier of states. And with a good deal of handwaving, the border between the Mexican Empire and the United States of Mexico is exactly the IOTL modern border between Mexico and the USA, even reflecting the Gadsen purchase. Since this is getting ridiculous maybe we let the liberals keep what is now Ciudad Juarez. The popular term for the northern Mexico state becomes "Texas" instead of "Northern Mexico", maybe there is a lot of Anglo immigration like there was IOTL.
