About 200 years ago the Cherokee Indians were one tribe, or "Indian Nation" that lived in the southeast part of what is now the United States. During the 1830's and 1840's, the period covered by the Indian Removal Act, (1) many Cherokees were moved west to a territory that is now the State of Oklahoma. A number remained in the southeast and gathered in North Carolina where they purchased land and continued to live. (2) Others went into the Appalachian Mountains to escape being moved west and many of their descendants may still live there now.
