How did African Americans win greater social rights between 1920 and the 1960's?

Between 1920 and the 1960s, African Americans gained greater social rights through a combination of grassroots activism, legal challenges, and the broader Civil Rights Movement. Key events, such as the Montgomery Bus Boycott and the March on Washington, mobilized public support and highlighted racial injustices. Landmark legal victories, including Brown v. Board of Education in 1954, helped dismantle segregation. Additionally, the efforts of organizations like the NAACP and the Southern Christian Leadership Conference (SCLC) played a crucial role in advocating for civil rights legislation.
