Final answer:
The statement is true. Throughout American history, Native Americans have created political and social movements to advocate for their rights, protest unfair treatment, and preserve their cultures and sovereignty.
Step-by-step explanation:
True, since the founding of the American republic, Native Americans have formed formal political and social movements to protest their mistreatment. For instance, the National Congress of American Indians was founded in 1944 and the American Indian Movement (AIM) in 1968. Renowned social campaigns, such as the protest against the Dakota Access Pipeline in 2016 by the Standing Rock Sioux and other groups, aimed to protect Native lands and cultures. Historical figures such as Helen Hunt Jackson and advocates like Sarah Winnemucca and Charles Eastman worked to raise awareness of the injustices suffered by Native Americans. Important legislative milestones include the Indian Citizenship Act of 1924 and the Indian Civil Rights Act of 1968, both of which sought to recognize and protect the rights of Native Americans.
