The impact I am looking for is post-1900, but, this thread is more appropriate for the pre-1900 because I believe the PoD would probably have to come well before 1900 for this to happen.
The challenge is to have an Amerindian group in the US or Canada become analogous to the Chechens in Russia, and remain so into the 20th century.
By analogous, I mean have a sustained violent separatist organization that sparks major US or Canadian military operations, perhaps they even win independence for a period.
Even when not possessing independence this group and its core territory should be largely ungovernable and make life extra dangerous for communities up to a few hundred miles around the groups core territory.
