Nevertheless, treaties and agreements gradually whittled away at this land base, and in the late 1700s, some Cherokees sought refuge from white interference by moving to northwestern Arkansas between the White and Arkansas Rivers.

In 1830 Congress passed the Indian Removal Act, which removed Native Americans west of the Mississippi River.
