Answer:
An effect of Great Society programs on Native Americans was that President Lyndon B. Johnson signed the Indian Civil Rights Act in 1968.
Step-by-step explanation:
The then President focussed on helping the Native American Tribes and considered that Indians were one of the vulnerable groups that needed help. This act granted Indians in America equal protection of the law. He addressed the National Congress of American Indians in January, 1964. So, Indian tribes were part of his “war on Poverty” program. The "war on Poverty" was part of Johnson's plan to create a prosperous nation, a place where the significance of the existence of man corresponds to the masterpieces of the effort of man.
