What was the most significant factor in helping the cause of Native Americans?

One of the most significant factors in helping the cause of Native Americans has been the increased awareness and advocacy surrounding their rights and issues, particularly from the mid-20th century onward. Movements such as the American Indian Movement (AIM) and key legal victories in courts brought attention to injustices faced by Native communities. Additionally, public support and the recognition of tribal sovereignty have played crucial roles in advancing their cause. These efforts have contributed to policy changes and greater representation for Native Americans in society.
