Hello,
Unfortunately, this is an overly broad question to answer. There is much more information needed to accurately address your inquiry. Which Nation, tribe and agreement (i.e. Indian Removal Act of 1830 by President Andrew Jackson and the Five Nations)? What era (Presidents Washington, Jefferson and Lincoln opposed)? Past or present (Original lands or Tribal/Trust lands today)? Note: Many thought (i.e. Davy Crockett, etc.) that the Indian Removal Act was unconstitutional but President Jackson eventually forced the Act (Trail of Tears).
Thank you,
Scott
