Which event is often regarded as a turning point in the Civil Rights Movement?

The Civil Rights Act of 1964 is widely regarded as a landmark piece of legislation that significantly advanced civil rights in the United States. This act aimed to eliminate discrimination based on race, color, religion, sex, or national origin. It represented a culmination of efforts made by activists, protests, and legislative battles and is often seen as a crucial turning point for the Civil Rights Movement because it not only enforced desegregation in public places and schools but also aimed to ensure equal employment opportunities.

The passage of this Act signified a federal commitment to civil rights and laid a legal foundation for further advancements in equality. Its broad scope helped empower civil rights activists and organizations to continue fighting for social justice, thereby accelerating the momentum of the movement.

While the other events mentioned in the choices were significant in their own right, the Civil Rights Act of 1964 stands out because it solidified the achievements of the movement into law, transforming American society and enforcing protections against discrimination in a way that prior events had not.
