Apparently you don’t know your American history. That is the area given to the tribes who were forced out of the American southeast. Now
Known as The Trail of Tears that forced deportation was and is a stain on the US govt.
This is a map of what was at that time
The ToT was a cruel farce worked on the Cherokee and others, supposedly in concord with a few Indian bigwigs who presumed to have command over the rest. Even most forced deportations are not death marches.
“Christian ethics” took a big nose dive here.
