Frequently Asked Questions

What is a treaty?

A treaty is an agreement between sovereign nations. See American Indian Treaties at the National Archives.


What treaties are included in this database?

You will find treaties and agreements between the United States and tribal nations from 1778-1886. This database is not necessarily comprehensive, rather it includes those published in the 1904 work “Indian Affairs: Laws and Treaties” (Volume II), compiled and edited by Charles J. Kappler.


What makes this database different from others?

There are many resources that include information about treaties in a variety of formats. For example, in 2020, the National Archives released hundreds of digitized treaties and made them available online through their catalog and via the Treaties Explorer database.

Oklahoma State University’s Tribal Treaties Database compliments existing work being undertaken by other academic, non-profit, and governmental agencies. Its underlying structure is created from the transcription of the treaties so that they can be easily searched. Additionally, we have added a newly created comprehensive index to supplement this work.
