Technically speaking, it's a tourist region in southeastern Montana that includes the Little Bighorn Battlefield National Monument. Here's what you'll find at its CusterCountry.com website:
Take in Custer Country
Custer Country is the home of 2 Indian Nations--the Crow and the Cheyenne. A proud and colorful history lives throughout our region and is expressed through celebrations, Pow Wows, and Crow Fair. Also, every year in June, at Little Bighorn Days in Hardin, visitors come from all over the world to watch the Reenactment of Custer's Last Stand. Action, color, shooting and the best bareback riding you've ever seen await you at this event. Finally, be certain that you save some time to visit the breathtaking art centers and museums to fully absorb the rich Indian cultural heritage.
Visit Custer Country, Montana, where losers go to die.
The site doesn't say much more about Indians. Its other main tabs barely mention them. This is most of what you get about the region's history.
The information isn't wrong, but it's been scrubbed clean of any controversy. Everything is "colorful" or something similarly upbeat. Nothing bad happened here except "Custer's last battle," after which I guess he retired to his estate.
What does the site omit? Well, Custer led a massacre of the Southern Cheyenne on the Washita River. He violated treaties by leading a gold-hunting expedition into the Black Hills. And at Little Bighorn he tried to kill thousands of Indians who wanted to live peacefully on their ancestral land.
At least the site doesn't call him a hero. But the name "Custer Country" seems an insult to the local tribes. He didn't live there or have any right of possession. All he did was visit once and foolishly get himself killed.
The land belonged and should belong to the Indians. It's Indian Country, not Custer Country. It would be like calling the 13 original colonies "King George III Country." Or calling Atlanta "William Tecumseh Sherman Country"--you know, because he marched through and destroyed it on the way to the sea.
Whitewashing Indian country
Custer Country has been incorporated since 1984, so I'm sure the Crow and Cheyenne have made their peace with it. But it's a typical example of how the winners write the history. Of how white Americans encode their version of events into the cultural landscape.
The implication of the name is clear. The land wasn't the Indians' to keep, it was Custer's to take. That he failed is a detail the US Army soon rectified.
Now the Indians are guests or tenants in the white man's land, not the other way around. Children grow up seeing and hearing Custer's name come first. The region features Custer, cowboys, dinosaurs, and...oh, yeah, some Indians too.

P.S. Someone noted the irony of this effort beginning in 1984. Yes, the date must've inspired them. War = Peace. Freedom = Slavery. Indian Country = Custer Country.
