Final answer:
The Montgomery bus boycott was successful due to the commitment of African American bus riders, the support from the community and leaders like Martin Luther King Jr., and the legal victory in Browder v. Gayle.
Step-by-step explanation:
The Montgomery bus boycott was a political and social protest campaign against racial segregation on the public transit system in Montgomery, Alabama. The boycott lasted for 381 days and was successful due to a combination of factors. One important factor was the commitment of the majority of bus riders, who were African Americans, to the boycott. They chose to carpool, walk, or use African American-owned taxis instead of riding the buses.
Additionally, the boycott received support from the African American community and leaders like Martin Luther King Jr., who emerged as a charismatic leader of the Civil Rights movement. The nonviolent nature of the boycott and the unity of the protesters also contributed to its success.
Furthermore, the legal victory in Browder v. Gayle, a Supreme Court decision that declared segregated buses unconstitutional, played a crucial role in ending the boycott and desegregating the buses.
