Final answer:
Native Americans achieved victories in the 1960s and 1970s through court settlements and legislation that secured their rights and autonomy.
Step-by-step explanation:
In the 1960s and 1970s, Native Americans achieved two significant victories in their struggle for rights and sovereignty. First, they won a variety of court settlements that provided financial compensation and legal autonomy, such as the Taos Indians regaining control of nearly 50,000 acres in New Mexico. Second, Native Americans appealed to Congress, leading to the passage of the Indian Self-Determination and Educational Assistance Act in 1975, which guaranteed tribes the authority to determine how to spend federal aid and administer their own educational programs.
