There's really no way outside of a POD that goes to the way back that would get the US to accept the Haudenosaunee or any Native tribe/confederation of tribes as a state within the Union. The US was sadly built on white supremacy, and keeping Natives out of their society went along with that (with individuals serving as exceptions, but I'm speaking about this in a more broad manner). At best they were considered primitives that could be educated into 'proper' civilization and even might get absorbed into the greater society of the settlers. But even the 'Civilized Tribes' were stripped of their lands and exiled once they got in the way of white expansion.
The only situation that could really shape out would be they somehow can function as a border state between the US and Canada, or more likely a surviving New France and the British colonies. Thande's TL Look to the West shows another example of the Haudenosaunee becoming protected subjects of the British crown after colonial reform leaves the British Colonies more of a separate empire that's in personal union with Britain. So in that regards it's more of an enhanced reservation/reserve system with their autonomy respected.
As a Mohawk I appreciate all those who really want to try and give us a better deal, but by this point we're fucked and there's really only a little bit of wiggle room to negotiate how fucked we get in the end. Sorry.
Building on the possibility listed here, ISTR another scenario where arriving Germanic settlers from Scandinavia and Continental Europe head west and establish a free state somewhere in the Upper Midwest. Assuming that could work out, maybe they ally with the various tribes not yet under government control (along with escaping refugees) and help give them some "teeth" against Anglo-American annexation? After all, the Germans were known for being more tolerant and fair with Native Americans than the rest of the Europeans arriving (notably, Fredericksburg TX is the site of the signing of one of the only Euro-Native treaties formed that was never broken by either party).
I meant AFTER the American Revolution. Granted that's probably too late for the Iroquois nation itself, but at least it's somewhere that could conceivably stand a chance against being conquered. As for the "unify and ally" thing, it's been brought up that there was no way in hell the Americans would ever respect the Native nations enough not to overrun them. I'm sure there were members of the Founding Fathers that would've been okay with that plan, but I doubt the average homesteader or land-hungry prospector would've given two shits what Ben Franklin or any of those Native-friendly persons would think.
Of course, there's the idea that the Continental Congress agrees to adopt a policy of coexistence with the tribe(s) if a way westward is left open in the process, and cracks down on expansion into the Native lands. It'd need a POD that changes Colonial attitudes towards the Tribes though, perhaps a different/butterflied French & Indian War?
No chance at all. Any treaty they could achieve with the US won't be worth the paper it's written on. Only if the land they lived on was considered a worthless desert that could make no money for the speculants.
2) if they are a state, they CANT restrict white immigration, and would be totally swamped.
Explain Hawaii then. That state has never had a white majority.
My understanding is that Hawaii had more Asian immigration than immigration from whites leaving the state (including everyone who isn't white) to have a majority in the area. A hypothetical Iroquois state in western New York would be far closer and end up being a majority white state, though one with a significant (relatively speaking) native minority, like New Mexico or Montana.
Perhaps, but the natives are a tiny fraction of the population, and have little sway over the state.Explain Hawaii then. That state has never had a white majority.
What you are suggesting might actually be feasible, BUT IN CANADA, NOT THE US. I could see the British making a treaty with all of the Haudanasee giving them the Mesopotamia, the territory between the St. Lawrence River and the Ottawa River, or even including some of the upper Ottawa and Northern as an organized Protectorate within the British Commonwealth. White settlement along Lake Ontario and Erie could simply leapfrog it. Unlike the Americans, when the British made a treaty like that, they generally kept it. And at Confederation in 1869, rather than a Reserve, Haudanasee could Confederate and get a seat in Parliament or two. Maybe some of the Five Nations could be elevated to the Peerage. All the Iroquois would need to migrate across the border to Canada soon after 1781 for this to work, though.
The British/Canadian governments kept treaties better than the US did - but that's not saying much. In addition, while they were much politer than the US, the natives got shafted worse in some ways. Look at the size of Canadian Reserves vs US Reservations.The British generally kept treaties? Maybe in North America, but the Australian Aborigines, the Maori and various Southern Africa tribes (not to mention India) would probably say otherwise and for good reason. And while Canada likes to portray itself as altruistic and such, bear in mind that they never had the same population pressures that the US had due to immigration and high birth rates, especially since most of Canada is a frozen tundra. I don't say this to justify American betrayal of the Native tribes, but Britain was certainly no more of an angel when it comes to dealing with non-white peoples where they settled than America was.
That being said, perhaps a protectorate in the location you mention (specifically the one north of Ottawa) could work out. The thing is to keep what westward expansion there is in Canada located closer to the Great Lakes or along the US-Canadian border.
