War Eagle, a Yankton Sioux chief in the 1830s, was a friend to the white man. Specifically, to the fur trappers who traded with the Yankton Sioux, Santee Sioux, Winnebago and other Native people at the confluence of the Missouri and Big Sioux rivers just outside Sioux City, in the northwest corner of what is now Iowa. But War Eagle’s hospitality and desire for peace eventually paved the way for white settlers to move in and push Native people out. Today, a monument to War Eagle, or Wambdi Okicize, stands on a bluff overlooking the Big Sioux River where the chief and his daughters were buried more than 150 years ago. It is a sacred place, locals say, from which one can see the expansive prairie that is South Dakota and Nebraska.
