Final answer:
The founding ideals for African Americans evolved from the Jim Crow Era to the rise of the Black Power Movement in the mid-1960s.
Step-by-step explanation:
The founding ideals for African Americans evolved from the Jim Crow Era to the rise of the Black Power Movement in the mid-1960s. During the Jim Crow Era, African Americans faced systemic racism, segregation, and disenfranchisement. However, with the rise of the Civil Rights Movement in the 1950s and 1960s, African Americans began to fight for their rights and demand equality.
Factors that helped advance these ideals included grassroots activism, protests, demonstrations, and the influence of leaders like Martin Luther King Jr. and Malcolm X. The Civil Rights Act of 1964 and the Voting Rights Act of 1965 were also significant milestones in advancing African American rights.
However, progress on these ideals was also hindered by resistance from white supremacists, Southern politicians, and the persistence of systemic racism. Violent responses to peaceful protests, such as the murder of civil rights activists like Medgar Evers and the bombing of the 16th Street Baptist Church in Birmingham, Alabama, were tragic examples of the obstacles faced.
