The Oneida Indians (who had only recently adopted the remaining Mohican Indians into their nation) allied themselves with the 14 colonies against the British and the other Iriquois tribes.
The Circle was broken, the council fires covered, and it was the end of the Iriquoian coprosperity sphere.
The Oneida/Mohican group WON. Then, the State of New York, in connivance with tens of thousands of illegal aliens, stole their land.
What they did was declare the Oneida to be "white people", and since "white people" couldn't own Indian land in New York, they took their land away from them.
A remnant of the Oneida identified under the "Munsee Band" (composed mostly of Stockbridge from Massachusetts, and Mohican from Hudson River communities, e.g. Schodack) live on the shores of Lake Winnebago. They operate a casino or two between there and Green Bay, WI.
Another band of Oneida managed to create Turning Stone Casino/Resort at Verona, NY. They are using the revenues to repurchase the lands stolen from them by the State of New York.
After two centuries of being treated quite brutally by their American allies, the Oneida/Mohican are finally in a position to get back their heritage.
You are correct. We're the losers now, because all of these casinos are opening up.
