What is Under termination policy Native American lost?

The Under Termination Policy refers to a period in U.S. history, particularly during the 1950s and 1960s, when the federal government sought to assimilate Native Americans into mainstream American society by terminating the special legal status of tribes and their federal recognition. This policy aimed to end the sovereignty of Native American tribes, leading to the loss of tribal lands, resources, and cultural identity. It resulted in significant social and economic challenges for many Native communities. Over time, this policy was largely discredited, leading to a shift towards tribal self-determination.
