Did the Opita Indians of Arizona sign a treaty?

The Opata Indians, primarily located in present-day Arizona and northern Sonora, Mexico, did not sign a formal treaty with the United States. Their interactions with the U.S. government were generally overshadowed by the treaties made with other tribes and the broader conflicts of the region. The Opata faced significant challenges due to colonization and were eventually displaced, leading to a decline in their distinct cultural identity.
